Overview

Honda Accord

Mainstream sedans and coupes represent far more than sensible transportation in today’s marketplace, and incredibly, include amenities that can often meet or surpass features on vehicles $20,000 more expensive. With every launch since its 1976 debut, the Honda Accord Honda Accord has lived up to its reputation as a genuine innovator, successively introducing the automotive mainstream to unexpected levels of technology and performance.

While dependability, quality and reliability define every Honda product, that solid base empowers the company to exceed customer expectations by providing styling, performance, safety, refinement and value that few competitors can match across the board. The all-new eighth-generation 2009 Accord is ready to set an entirely new benchmark for the automotive mainstream with the most dramatic styling, the largest passenger space, and the greatest range of technology in the vehicle’s 32-year history.


Honda Accord

The 2009 Accord comes to market as the most powerful Honda model ever. It has also grown larger to meet the needs of an audience that values hospitality with "equal" front and rear seating comfort for four adults - while also maintaining or improving its fuel economy, lowering its emissions and building on its reputation as a class leader. From a pure performance standpoint, the Accord’s 268-horsepower V-6 engine provides acceleration on par with luxury vehicles from classes outside of the segment.

Dynamically, the Accord engages the driver with a refined and rewarding performance feel, yet ride comfort remains equally impressive for passengers. Furthermore, the level of standard equipment and premium features allow customers to create an environment that matches 21st century expectations. Ultima Ultima tely, the 2009 Accord adds more emotion and style to the model’s smart-to-own foundation in an all-out effort to genuinely deliver on the promise of an "evolution of the best" with one of North America’s favorite cars.

The launch of the 2009 Accord represents three notable firsts for Honda in North America and more than 20 notable firsts for the Accord model range.

The Accord DNA

Honda Accord

The Accord has always occupied an extremely important position within Honda and within the automotive marketplace. It is more than just the company’s flagship passenger car from engineering and sales standpoints. Reliable, safety-oriented and efficient, the Accord is also the most comprehensive expression of Honda’s DNA worldwide. More than anything else, the Honda Accord stands for:

  • Fun-to-Drive - The 2009 Accord model range introduces Honda’s most powerful passenger-car engine in North America, and its double-wishbone front suspension provides a solid feel unlike anything in its class.
  • Durability, quality and reliability (DQR) - Year in and year out, the Accord is consistently a high scorer in initial and long-term quality studies.
  • Safety - With Honda’s Safety for Everyone initiative, every trim level of the 2009 Accord contains an extensive range of safety technologies, from its Advanced Compatibility Engineering™ (ACE™) body structure to its airbag systems and active front seat head restraints.
  • Value - Strong Honda resale value and low maintenance costs help make the Accord historically smart-to-own in the long run as referenced by leading industry resources.
  • Versatility - With a new interior that is 3.3 cu-ft. larger than before, the Accord Sedan offers more roominess and comfort than ever. The Accord Sedan’s expansive interior volume of Environmental - Honda has the highest Corporate Average Fuel Economy (CAFE) ratings in America . The 2009 Accord, with two new 4-cylinder engines and two new V-6 versions, is more fuel-efficient . In addition, automatic transmission Accords meets stringent PZEV (Partial Zero Emission Vehicle) standards in states using that standard.

 

2009 Accord Advancements

Honda Accord

As Honda’s highest-volume seller in the U.S., by necessity Accord strives to deliver exceptional feature content including outstanding driving qualities, a high level of interior comfort and convenience features, consummate DQR, and the benefits of Honda’s Safety for Everyone initiative. By design, the Accord Coupe is free to connect with a select range of customers that place a high value on sporty style and driving excitement. Stylistically as well as dynamically, the Accord Coupe distances itself from the Accord Sedan to satisfy more enthusiastic drivers with a unique set of attributes all its own.

Durability, Quality and Reliability

For many customers the Durability, Quality and Reliability (DQR) of the Honda Accord is what keeps them returning generation after generation. These fine qualities - and the resale or trade-in value they engender for the Accord - become a powerful purchase incentive. Virtually every major company that studies vehicle residual value have shown that the Accord typically has one of the highest residual values in the industry. As an end result, a high residual or resale value makes the true cost of ownership less than many lower-priced competitors.

Honda Accord

Market Position

The Accord has consistently been one of the top five best-selling vehicles in the U.S. for nearly two decades. As Honda’s best-selling vehicle in U.S., Accord is the bedrock of the company. The sedan market in the U.S. is consistently strong, with annual sales in the neighborhood of 2,000,000 units, with Accord accounting for nearly one-fifth of all Midsize vehicles sold. Accord appeals directly to two of the growing segments in the automotive market - young couples and empty nesters. As these people seek sophistication and fun combined with great resale value and quality in their vehicles, Accord meets their needs and desires. At the same time it appeals to the more practical virtues of a great family vehicle.

In contrast, the Accord Coupe has historically appealed to singles, young couples without children and "empty nesters" that want to capture the spirit of driving that a coupe provides. Today’s sports-coupe buyers want even more emphasis on sportiness and that is the reason why the 2009 Accord Coupe so visibly stands apart from the sedan - both visually and in handling performance.

Primary Competitive Set

Honda Accord

Though the Accord Sedan has just over 120 cu-ft. total interior volume and is classified as a Large sedan by the EPA, its prime competition remains in the upper end of the EPA Midsize class. The Midsize sedan segment is one of the most competitive in the entire automotive field with more than 20 unique model lines from manufacturers large and small all vying for customers’ attention. With top-selling products achieving sales figures in the neighborhood of 400,000 units per year, broad appeal is essential to success. Likewise, design, engineering and quality must reach the highest standards. As with products across the auto industry, buyer expectations for Midsize sedans are evolving to favor products with more interior room and personality.

The primary competitors to the 2009 Honda Accord are the Toyota Camry and the Nissan Altima. The Accord Sedan is well positioned to compete with these vehicles with its expansive interior, more daring styling, excellent driving character, overall quality and high levels of safety. Beyond its direct competitors, the Accord Sedan also competes with a secondary set that includes the Nissan Nissan Maxima and Toyota Avalon. The primary competitor for the Accord Coupe is the Nissan Altima Coupe and Toyota Solara.

Exterior

Honda Accord

The Accord Sedan embraces a traditional three-box shape that emphasizes both a dynamic and athletic feel with the sophistication of a timeless sedan form. The design is intended to convey a prestigious presence toward family, friends and business associates in much the same way a good suit can be worn on totally different occasions with a consistent feeling of style and class.

The focal point for creating the exterior began with the belief that a sedan should reflect both American values and embrace values shared worldwide. Truly a global effort, the Accord design theme of "athletic dynamism" brings together contributions from Honda design centers in Italy, Germany, Japan and the United States.

Dimensionally, the Accord Sedan’s overall length of 194.1 inches (4-cylinder models) is 3.0 inches longer than the 2007 model, the width of 72.7 inches is 1.1 inches wider, and the height of 58.1 inches is 0.9 inches taller. Even though the size is larger in every dimension, the vehicle’s torsional rigidity has increased by 20% as a result of advanced body construction that uses 48% high-tensile steel - the most high-tensile steel by volume of any Accord to date. A significant benefit to the advanced body construction is that total vehicle weight increased only by approximately 5% despite the larger size, greater rigidity and added features.

Honda Accord

The Accord Coupe styling radically breaks from the sedan with a uniquely aggressive image. Its long hood, sleek roofline and muscular lines suggest an even more powerful presence and a heightened agility compared to the sedan. Dimensionally, the Accord Coupe’s overall length of 190.9 inches is 3.1 inches longer than 2007 model, its width of 72.8 inches is 1.2 inches wider, and its height of 56.4 inches is 0.6 inches higher. Compared to the 2009 Accord Sedan, the Accord Coupe is 3.2 inches shorter in length, 1.7 inches shorter in height and 0.1-inch wider.

Interior

Honda Accord

Premium quality with a simple, modern and spacious design describes the philosophy behind the Accord’s interior. Rather than adding feature after feature to assault the senses with opulence, a variety of design techniques were used to enhance the feeling of width and space to express premium quality. Considerable attention was paid to interior shaping and detailing just as it was for the exterior, where the traditional three-box sedan form was enhanced by sculpting of the body panels. The exterior concept of using a beveled corner where the front bumper and fender meet is similarly applied to the lower part of the instrument panel to create a spacious feeling while entering the vehicle. Careful attention was paid to the symmetry of the exterior and interior of the vehicle - including sight lines related the dashboard height and the visual presence of the hood to the driver.

Honda Accord

While the interior is larger than the previous-generation Accord, the fundamental reason for increasing its size is grounded in the goal of producing equal seating comfort for front and rear passengers. In other words, the vehicle provides a sense of true hospitality to all of its occupants.

Real differences in usable space can be noticed in the hip-point distance between front and rear passengers (+ 1.0 inch compared to the 2007 model).

Furthermore, the increased hip-point distance and lower floor allows rear occupant knee space to increase by three inches compared to 2007. By Honda’s in-house measurements, the few sedans on the market with more rear knee space include the Mercedes Benz S550, BMW 750i and Lexus LS 460.

The wider interior (+1.5 inches), combined with a more compact lumbar support system (EX and above), allows the front seats to be positioned farther apart to allow for a 2.75 inch wider center console compared to the 2007 Accord. Not only does a wider console provide the obvious enhanced functionality, but it also conveys a sense of openness more commonly found on high-end luxury vehicles.

Honda Accord

A traditional zone approach separates operation-related instruments (top) and information-related instruments (lower). At night, the controls are further separated by color to distinguish between climate controls (aqua green) and audio controls (white). Classically-styled gauges for the speedometer and tachometer are round (instead of being truncated at the bottom). The steering wheel was meticulously fashioned with a shape, size and mass consistent with the finest luxury automobiles.

Overall, the 2009 Accord Sedan has gained 3.3 cubic feet of interior space (120.0 cu-ft. total). Sedan customers traditionally value the comfort and utility of greater interior space, and as a result, the new Accord looks, feels, and simply is bigger. The Accord offers more interior space than its prime competitors in most dimensions. Building on Honda’s already excellent reputation for interior styling (one of the significant strengths of the previous generation Accord), the new Accord has an even more upscale presence.

Powertrain

Honda Accord

All 2009 Accord engines deliver increased horsepower across the board, along with high fuel efficiency and low emissions. The sedan is available with either a 177-horsepower engine (up 11 horsepower) or a 190 horsepower 4-cylinder engine (up 24 horsepower) with a choice of 5-speed manual transmission (standard) or 5-speed automatic transmission (available), or a 268-horsepower V-6 with a 5-speed automatic transmission. The Accord Coupe is offered with a 190-horsepower 4-cylinder engine (up 24 horsepower) or a 268-horsepower V-6 engine (up 24 horsepower) with a choice of 5-speed manual (4-cylinder) 6-speed manual (V-6) or 5-speed automatic transmission (all engines). In total, these powerplants represent the most powerful and advanced technologies of any Accord in history, and are also projected to deliver excellent real-world fuel economy performance.

Honda Accord

Body

With its new larger size and bold, sophisticated styling, the 2009 Honda Accord Sedan aims to become the benchmark in its category. More dynamic and emotional in design than any previous Accord generation, the 2009 Accord Sedan grows more expressive in its sedan style with more a substantial front end with a distinctive 6-sided grille, taller hood line, more aggressively arched fenders, unique upper and lower style lines along the body sides, and a dynamic sweeping roofline with chrome window trim.

Honda Accord

For 2009, the new Accord Coupe dramatically breaks from the Accord Sedan with 100% unique sheet metal, glass and exterior lighting that creates a rakish and aggressive appearance. From its recessed grille, projector-beam halogen headlights and flared wheel arches to its 18-inch wheels - a first for Accord and the biggest ever for a Honda automobile - the Accord Coupe V-6 pushes Accord to new levels of excitement.

2009 Honda Accord Sedan

Design Concept
To stand out among expressive midsize competitors such as the Nissan Altima and Volkswagen Passat, styling for the new Accord had to be more expressive and dynamic. The designers sought to create a new Accord style that is:

  • Powerful
  • Bold
  • Sophisticated
  • Prestigious
  • Distinctive
Honda Accord

The Accord Sedan design is both sharp and strong, with a powerful-looking stance. Starting at the front, the Accord Sedan’s nose is pushed out and raised for dynamic character, and incorporates a strong 6-point grille surrounded by chrome detail, sharp and wide headlights, and well-defined wheel arches that provide a strong stance and muscular tension.

The hood line is taller by more than two inches, and together with the more upright appearance of the grille surface, results in a particularly strong character. The flow of the Accord’s dynamic lines is intentionally reminiscent of the Honda S2000 sports car.

The fender lines are broad, like strongly muscled shoulders, with prominent character lines that sweep along nearly the entire body sides, and wrap across the trunk lid. Besides providing visual distinctiveness, these character lines convey strength and structural depth.

Spacious
For the first time the Accord Sedan is classified as a Large Sedan by the EPA. Its increased size brings passenger volume to 106.0 cu. ft., a 3.3 cu. ft. (3.2%) increase over the 2007 Accord Sedan’s 102.7 cu. ft. of passenger volume. As a result, the new Accord looks, feels, and simply is more spacious - with improved ingress and egress as well.

Honda Accord

In fact, the new Accord is larger in all key exterior (and interior) dimensions. By comparison to the 2007 Accord, it is three inches longer, its wheelbase is up 2.3 inches, its track width is an inch greater, and overall width has increased by over an inch. The 2009 Accord Sedan also comes standard with 16-inch steel wheels with wheel covers, or16- or 17-inch aluminum wheels depending on model. (The Accord Coupe has 17-inch aluminum wheels standard, with 18-inch aluminum wheels available on the Coupe V-6). The 17-inch wheels are the first for a four-cylinder Accord and the Coupe’s available 18-inch wheels are the largest ever for a Honda Coupe.

Headlights
The Accord Sedan uses headlight arrays inside styled clear lenses that subtly protrude from the body contours for enhanced visual presence. Meticulously designed and detailed, the halogen low and high beams, along with the accompanying turn signals, have a sophisticated, technical appearance.

Door Handles

Honda Accord

All Accord V-6 models have stylized chrome-plated exterior door handles. The four-cylinder models have body-color matched door handles. All door handles are soft to the touch underneath to improve operating comfort.

2009 Honda Accord Coupe

With its combination of aggressive styling, dynamic performance and advanced technology, the 2009 Accord Coupe’s design philosophy is aggressive and powerful. Its sophisticated design takes the Accord Coupe further toward exciting, sporty performance than any Accord Coupe in history - and then delivers on that promise. There are no visible exterior body panels, lights, glass, grille or bumpers shared between the Accord Sedan and Accord Coupe - only the door mirrors and door handles are common. Beneath the skin, the underlying chassis construction is the same between the Sedan and Coupe, except that the Coupe wheelbase is 2.3 inches shorter.

Accord Coupe Design Philosophy

Honda Accord

The 2009 Accord Coupe’s exterior styling reflects its fun-to-drive nature. That’s by design, because Honda wanted to expand the segment by creating a more sporty and aggressive car. Thus the Coupe’s goal is to be the sporty leader, not only with its styling but its driving excitement as well.

Exterior features back up the Coupe’s styling and the driving mission. Every Accord Coupe has a deck-lid spoiler and large exhaust tips with 2.25-inch openings. Four-cylinder Accord coupe comes with 17-inch alloy wheels and the Accord Coupe V-6 has standard 18-inch alloy wheels.

Accord Coupe Front Grille
The Accord Coupe has a powerful and sporty-looking 6-point grille, with a unique 3-dimensional bar and mesh design. Beneath the grille is a broad air dam with aggressively sculpted channels to direct airflow and provide visual identity. Widely spaced fog lamps are integrated below the headlights on V-6 models.

Honda Accord

Accord Coupe Profile
Along the side of the Accord Coupe body, strong character lines extend from the front fender nearly to the tail lamps. The roofline is streamlined and flows aerodynamically from the top of the A-pillar to the rear deck. Long doors provide a generous 43-inch opening for easy entry and exit, while an aggressive wedged shape builds a unique identity for the Coupe.

Accord Coupe Projector-Beam Halogen Headlights
The 2009 Honda Accord Coupe is equipped with projector low-beam headlights. Projector headlights provide a distinctive sporty appearance with a bright, focused beam for confident nighttime driving. Flush-mounted clear covers blend in with the Accord Coupe’s front fender lines for a sleek appearance. On the V-6 models, fog lamps are also recessed more deeply into the front bumper than the Sedan’s.

Accord Coupe Tail Lamps
Brake light and tail lamps are unique to the Accord Coupe. As aggressive as the front end and headlights, they promise both performance and attitude, and their compact dimensions contribute a precise look.

Accord Coupe Wheel Design

Honda Accord

The Accord Coupe has standard 17-inch alloy wheels with five pairs of sharply sculpted spokes. The available 18-inch alloy wheels have ten evenly spaced, smoothly contoured spokes.

Shared Body Design Elements

High-Strength Sheet Steel
The body uses 48% high-strength sheet steel for greater stiffness and reduced weight, compared to 39% in the previous-generation Accord. This greater use of this steel (590 and 440 grade) reduces body weight while increasing rigidity, which pays dividends in ride, handling and interior quietness. This also helps the 2009 Accord target the top durability, quality and reliability (DQR) in its class.

Increased Rigidity

Honda Accord

New design techniques and the widespread use of high-strength sheet steel make the 2009 model the stiffest Accord ever, and yields benefits in ride, handling and overall durability. With the most high-strength steel of any Honda car in history, the 2009 Accord is stronger as well as larger, without imposing a significant weight increase. Specific improvements are found in the rear of the vehicle, where 33% greater vertical rigidity directly enhances ride quality and handling.

A summary of Accord’s rigidity improvements compared to its predecessor include:

  • 20% greater torsional rigidity
  • 33% greater rear vertical rigidity
  • 36% greater front horizontal rigidity

 

Frame Rail System

The 2009 Accord is the first vehicle to use Honda’s new unit-body frame rail system. Positioning the stamped steel frame rails above and inside the Accord’s body structure floor - instead of underneath it - creates a nearly flat bottom under the car. The result is greater aerodynamic efficiency for improved fuel mileage, and reduced interior noise that can result from air turbulence underneath the car. The Accord’s new frame rail design does not compromise interior room.

Honda Accord

Advanced Compatibility Engineering (ACE) Body Structure

The Advanced Compatibility Engineering™ (ACE™) body structure is a pioneering Honda unit-body construction technology. Introduced to Accord for the first time in the 2009 model, it maximizes the body’s ability to disperse crash energy in a frontal collision and is designed to deliver top safety ratings. The 2009 Accord Sedan and Coupe are projected to receive a 5 Star frontal impact rating from the National Highway Traffic Safety Administration (NHTSA*) and a "Good" frontal crash safety rating from the Insurance Institute for Highway Safety (IIHS). (Please see Safety tab for more information.)

Bumpers
Front and rear plastic bumper fascias on the V-6 models are uniquely sculpted for enhanced visual appeal. (Please see Safety tab for more information.)

A-Pillars
More slender body A-pillars, constructed of high-strength steel, provide a greater field of view without compromising strength. Based on Honda internal measurements, the new A-pillars allow a greater effective visibility rate (the index for visibility during cornering) than either the Toyota Camry or Nissan Altima.

Noise Reduction Features

Honda Accord

All Accord models use a dual door-seal system to reduce the possibility of wind noise or rain intrusion. To further reduce operating noise, the 200-hp four-cylinder and V-6 Accords feature under-hood noise insulators and acoustic engine covers. Accord Sedan and Coupe V-6 with automatic transmission, and all four-cylinder EX models, also feature a special Active Noise Control (ANC) system. (Please see Interior tab for more information.)

Fuel Tank
Fuel capacity has increased to 18.5 gallons from 17.2 gallons, an increase of 8%. The most ever offered on Accord, the additional fuel capacity helps extend cruising range between fill-ups. Made of polypropylene resin, the tank is located farther forward than in the previous generation Accord, helping to improve mass centralization for better ride and handling, and rear-seat roominess.

Aerodynamics
Reducing audible wind noise was an important Accord engineering goal, particularly high-frequency noise that can be distracting and impede conversation. The flatter bottom of the car, together with careful tailoring of the body shape, window moldings, windshield wipers and outside mirror shapes, all play a part in reducing wind noise.

Honda Accord

Aerodynamic efficiency is likewise improved. The coefficient of drag for the 2009 Accord is just over 0.31 Cd for the Sedan and 0.33 Cd for the Coupe. This compares favorably with the 0.34 Cd figure for the previous generation Accord. In addition, the Accord’s coefficient of lift (Cl), which indicates how much body lift occurs at speed, drops from over 0.20 Cl to just over 0.17 Cl for the Sedan and 0.14 Cl for the Coupe.

Additional under-vehicle aerodynamic aids include a wide chin spoiler that directs air under the front subframe. Additional strakes are positioned ahead of the front and rear wheels, plus two additional deflectors that smooth airflow over the front suspension. An engine under-cover directs airflow under the engine, while two middle under-covers direct air around the edges of the fuel tank.

Moonroof
In addition to being lighter and wider, and offering a greater opening range, the moonroof operation is also improved. To tilt or slide the moonroof the driver or front passenger needs only to fully press the ceiling-mounted switch once (instead of pressing and holding it for several seconds). The moonroof fully opens or closes automatically. However if the operator wishes to only partially open or close the moonroof (such as to achieve partial ventilation), a lighter touch yields fully manual control. The moonroof can also tilt to provide ventilation. A pinch protection feature is built in, helping to ensure that the moonroof will not forcefully close if someone’s hand or arm is positioned in the path of the moonroof. If an obstruction is detected, the moonroof mechanism will reopen the moonroof.

Honda Accord

Power Windows
In addition to an auto up/down driver’s window feature, every 2009 Accord model except the LX Sedan has an auto up/down feature for the front passenger’s window. As with the moonroof, the power windows include a pinch-protection feature. All power side windows and the moonroof may be opened via the keyless remote. In addition, turning the key twice in the driver’s door lock simultaneously closes the windows and moonroof.

Windshield Wipers
The windshield wipers on the 2009 Accord Sedan and Coupe are tucked below the hood line, out of the direct airflow over the hood to reduce turbulence, aerodynamic drag and noise. The arms are unobtrusive to the driver’s field of view, and their clean design allows air to flow past with less turbulence.

Trunk
Large storage volume is a big selling feature for sedan customers. With 14.0 cu. ft. of storage space, the new 2009 Accord Sedan matches the excellent trunk volume of the previous generation. The exterior appearance of the trunk lid is improved by the elimination of the key cylinder. On all 2009 Accord models, the trunk is released via a lever located on the driver’s side floor, or else by the trunk-release button on the remote.

Honda Accord

Some of the target cargo capacities for the 2009 Accord Sedan include up to four typical suitcases or two large suitcases, four golf bags, a stroller or wheelchair, or a large ice chest. The lift-over height is a low 28 inches for the Sedan and 31 inches for the Coupe. The trunk is a generous 46.75 inches long in the Sedan and 46.5 inches long in the Coupe, allowing the storage of some surprisingly long items. Maximum trunk width is likewise impressive at 55.5 inches for both vehicles. In the Coupe, when the rear seat is folded down, the maximum storage length grows to 76.5 in. The Coupe trunk volume is 11.9 cu. ft.

The steel trunk lid has a composite garnish at the bottom rear, which can be replaced after a collision. This lowers repair costs to lend a more favorable profile for the Accord in IIHS repair-cost studies.

Chrome Trim
In keeping with its expressive nature, the 2009 Accord has more chrome-appearance accent pieces. On all V-6 models the door handles are of a chrome appearance vs. painted on the four-cylinder models. In addition, all Accord models except the LX Sedan have chrome-plated muffler tips for a more sporty appearance.

Exterior Colors

Honda Accord

The 2009 Accord offers a dynamic color palette that adds character and boldness to both the Sedan and Coupe. All-new colors for the 2009 Sedan include Mystic Green Pearl, Polished Metal Metallic, Bold Beige Metallic and Basque Red Pearl. White Diamond Pearl is an all-new and exclusive color for the V-6 Sedan. For the 2009 Coupe, Belize Blue Pearl and Polished Metal Metallic are new additions to the color lineup. All the new colors change in appearance depending on sunlight conditions, further amplifying the Accord’s dramatic bodylines.


Interior

The Accord Sedan and Coupe appeal to a wide range of male and female buyers - from couples with no children to empty nesters and retirees. Comfort, quality, style and functionality are important to all of these groups because many have active lifestyles. Some need a vehicle functional enough to serve as a daily commuter, others need a vehicle elegant enough to transport business associates, while other groups seek stylish and comfortable transportation. The 2009 Accord Sedan and Coupe serve all these needs exceptionally well.

Honda Accord

Before designing the 2009 Accord, Honda visited distinct types of people in different parts of the U.S. to observe how they use their vehicles and what features they appreciate and want. High on their list was ease of entry and exit, followed by seating comfort, quality, style and versatile storage capability. Logically, they found that professionals and couples use their vehicles for a range of activities including commuting, client activities, travel with friends, sports and pleasure, while young married couples use them primarily for social and recreational activities.

Beyond Midsize Spacious Interior
The 2009 Accord Sedan is the first Honda car to move to the EPA Large classification from the Midsize category. Now the Accord Sedan offers the largest interior in its class, although customers will still typically compare it to midsize competitors. The Sedan is rated at 106.0 cu-ft. of passenger volume, a 3.2% increase over the 2007 Accord Sedan. Total interior volume (passenger plus cargo volume) measures 120.0 cu. ft.

 

Interior Styling

Honda Accord

The interior is designed to be sophisticated, comfortable and useful - a perfect balance of the rational and emotional. Design goals were a simple and clean style with a premium look that evokes an upscale and elegant feel. Key concepts that designers used in creating the interior include:

  • Simply premium - Stylish and intuitive interface between passengers and technology.
  • Comfortable - Wide spacious feeling with a wide console area.
  • Powerful and Personal - Including the use of bold colors and materials.


Accord Coupe Interior Design

The new Accord Coupe interior retains the premium look of the sedan but is more powerful, personal and sporty in appearance. The Coupe interior has several unique components including the front and rear seats, door panels and rear side panels, along with an exclusive 3-spoke sport steering wheel. Components shared with the Sedan include the instrument panel and center console, some seat components and the upper portion of the front cabin.

Honda Accord

Interior Features

Interior Materials
The 2009 Accord interior exhibits high quality and refinement throughout, even down to the feel of the switchgear, console and door panels. The available leather is softer and more supple than the leather used in the previous Accord models. In addition, the upper portion of the instrument panel (including the SRS lid) is now made with the same material and finish for improved consistent appearance.

Instruments
Two large analog meters, surrounded by silver trim rings, provide a premium sporty appearance. The instruments use white numerals and bright red needles for easy information access at a glance. The 8000-rpm tachometer and 160-mph speedometer are flanked by temperature and fuel gauges. Below the meter array is an LCD odometer display that can show odometer, Trip A or Trip B functions. Maintenance alerts also appear on this display.

Steering Wheel

Honda Accord

The 4-spoke steering wheel on the Accord Sedan (leather wrapped on EX-L and V-6) creates a luxury feeling while the Accord Coupe gets a unique 3-spoke steering wheel (leather wrapped on EX-L and V-6). In another first for Accord, all 2009 Accord models offer steering-wheel mounted audio and cruise-control switches including Mode, Volume and Channel, plus Cruise, Cancel, Set/Decelerate and Resume/Accelerate. In models equipped with the navigation system, the steering wheel also features switches for navigation voice control, and for the driver’s compatible Bluetooth® HandsFreeLink™.

Center Panel
The Accord’s new center panel has been carefully designed for maximum visibility and ease of use. Its large central display is mounted at the top of the center stack for easier visibility, and the switches are mounted lower for easier reach. All components are flush mounted with high-grade materials for an upscale appearance and feel.

Center Console
The center console offers storage including a covered forward box, a covered two-level console with armrest, and new covered holders that accommodate two large cups. The console is nearly three inches wider than that of the previous generation Accord to ensure more storage space for personal belongings. A new spring system improves the operating feel of the cover, which doubles as the center armrest. In addition, the console offers 5.4 liters of storage space (up from 5.2 liters in the previous-generation Accord) and can now store 22 CDs (up from 20 CDs). The armrest slides fore/aft nearly a half inch more for improved comfort for drivers of different heights.

Seats

Honda Accord

The new Accord’s front seats are broader, more comfortable and have supportive side bolsters to help keep the driver and front passenger securely in position during cornering. The rear seat offers substantially more legroom than in the previous generation Accord, and offers a clean, flowing style that mirrors the rest of the interior. Likewise, the Accord’s larger interior volume allows more room between passengers. There is nearly 1.6 inches more room between the driver and front passenger, and over an inch more room between front and rear passengers.

Power Seats
An 8-way power driver’s seat is standard on all models except Accord Sedan LX and Accord Coupe LX-S. Accord V-6 models features a 4-way power passenger’s seat.

Power Driver’s Lumbar Support
A power driver’s lumbar support is standard in EX, EX-L and V-6 models for the first time in Accord history. Switching to electric activation from manual activation offers more than just convenience - the new lumbar support offers nearly a half inch more lumbar support than the previous generation Accord.

Adjustable Steering Column
The tilt range for the steering column (now nearly two inches compared to 1.6 inches in the previous-generation Accord), along with a nearly 0.6-inch greater seat height adjustment range, enhances comfort for a wider array of drivers.

Honda Accord

Rear Seat Entry and Egress
In the coupe, the passenger-side front seat has a one-touch release that folds the seatback and allows the seat to slide forward to make rear-seat ingress and egress simple.

Center Display
The center display provides an important advancement in usability and convenience. Its easy-to-see location at the top of the instrument stack allows the driver to quickly see information. In fact, the new 2009 Accord display requires just 17 degrees of driver eye movement - an improvement over the previous Accord. The LX display shows clock and audio-system information, while the EX’s 3-line display features a digital clock, audio mode, and track and time information for XM, CD and MP3. Dual HVAC temperature readouts and a digital compass are included in Accord EX with Leather.

Underneath the center display are two movable HVAC vents, the emergency flasher switch and a passenger-airbag off light. Below the vents are the HVAC controls. Audi Audi o-system controls are located in a separate row and feature larger switches that are easier to identify at a glance. At the bottom of the stack, LX models have easily accessible volume and tuning knobs. EX models also have an interface dial in this location, flanked by Menu and Cancel switches. The dial is rotated to select among different on-screen items. Pushing the controller selects the highlighted item.

Honda Satellite-Linked Navigation System™ with Voice Activation

Honda Accord

The Honda Satellite-Linked Navigation System™ is available on the EX with Leather (EX-L) and V-6 trim levels. Similar to the system used in the Acura RL, it features improvements that make it the most sophisticated Navi system ever available on a Honda Honda . Upgrades from the 2007 Accord system include a new 8-inch screen and Bluetooth® cell-phone connectivity. It also features a nationwide Zagat Survey™ guide for restaurants, nightlife, hotels and attractions.

In developing the 2009 Accord’s controls, Honda focused on making safe driving the primary task, with the controls designed and positioned logically. As such, the navigation system has been reworked to make it easier to use. In addition to being larger, the display screen is now positioned higher in the instrument panel, recessed more deeply to be better shaded from glare and positioned farther away for more convenient viewing.

The Navigation system’s simplified controls are designed to be used at a glance - or without looking at them at all. The system can be controlled by voice, or by the interface dial with clear tactile feedback that speeds control inputs and reduces the need to look at the screen to confirm the system’s response. With these voice commands and prompts, the driver can control the system, and get feedback and directions without looking away from the road. For voice operation, the driver simply presses the "Talk" button on the steering wheel and says any of a number of preset command phrases. The system also incorporates a hands-free Bluetooth® HandsFreeLink™ phone system that automatically links to the driver’s cell phone address book once a simple setup procedure is performed.

Bluetooth® HandsFreeLink™ Wireless Telephone Interface

Honda Accord

Another first for the 2009 Accord is the new available Bluetooth® HandsFreeLink™ hands-free phone interface. Designed to work with many Bluetooth® enabled mobile phones, the system uses radio frequencies to connect the driver’s cell phone to the Accord’s Wireless Telephone Interface. This allows the driver to make or answer cell-phone calls without taking his or her hands from the steering wheel. The system is compatible with Bluetooth® enabled cell phones that have the Hands Free Profile (HFP).

HandsFreeLink™ is designed for easy use. After the driver completes a one-time "pairing" process to link the cell phone with the Accord, HandsFreeLink™ can communicate wirelessly and securely with the driver’s cell phone when the phone is within about 10 feet of the car. Once the driver enters the car, he or she simply stores the phone in a pocket, briefcase, purse or a storage bin inside the Accord cabin and the call transfers through the Wireless Telephone Interface.

Audio Systems
A pair of audio systems are available in the 2009 Accord Sedan and Coupe. The standard 160-watt system includes an AM/FM receiver with a single CD player and six speakers, plus an MP3/aux-in accessory jack. A large-format display provides system information, and steering-wheel audio controls are standard in all 2009 Accord Sedan and Coupe models. An in-glass antenna pulls in AM and FM signals without the visual or mechanical complexity of a power mast antenna.

Honda Accord

Radio Data System (RDS)
Included in all 2009 Accord models, the Radio Data System (RDS) expands the capability and functionality of the audio system. By continuously receiving and interpreting a 57 kHz FM subcarrier frequency, the Accord radio can automatically display the radio station ID, music track name and artist on stations that provide this information.

Honda Premium Audio System
The Accord’s premium audio system features a 270-watt main amplifier and seven speakers (including the first use of a factory subwoofer in an Accord), and comes standard on all Accord EX-L and V-6 models. Designed to outperform the top competitive sound systems (engineered by Bose in the Nissan Altima and JBL in the Toyota Camry), the Honda Premium Audio System offers serious audio power and clarity.

The four main speakers feature 6.7-inch Kevlar cones for reduced distortion and improved sound reproduction. Twin tweeters, mounted on the A-pillars, use an aluminum dome instead of the traditional soft dome to reduce distortion by some 10 dB. This likewise improves sound quality with clearer high frequencies. Finally the 7.9-inch subwoofer, mounted behind the rear seats, is driven by a devoted 90-watt amplifier to provide powerful, defined low-frequency tones in the 30-50 Hertz range.

Honda Accord

The system offers song-scrolling capability through an interface dial when playing CDs that provide this data. The song title appears on the Information Display, which can show three lines of text. In addition, the system features a 6-disc CD changer. XM Satellite Radio comes standard on Accord EX-L and V-6 models.

Speed-Sensitive Volume Compensation (SVC)
All Accord audio systems incorporate speed-sensitive volume control (SVC). If the driver so chooses, SVC automatically adjusts the volume as the vehicle’s speed increases to counteract the gradual buildup of road and wind noise. Low, medium and high operating modes are available. The system may also be disabled at the driver’s preference.

Auxiliary Input Jack
For the first time, the 2009 Accord comes with an auxiliary input jack (aux-in) that allows the easy connection of personal audio players to the audio system. The aux-in jack is conveniently located in the center console, along with a 12-volt power point that can charge the personal audio player. Plugging a portable audio device into the aux-in jack automatically sets the volume at a preset level; when the device is unplugged, the volume resets to its previous level.

Active Noise Control (ANC)
The 2009 Accord has the latest version of Active Noise Control (ANC) first introduced on the previous-generation Accord Hybrid. Now standard on the 2009 Accord V-6 Sedan and Coupe equipped with automatic transmission, and all 190-horsepower four-cylinder models, ANC significantly reduces certain low-frequency sounds in the interior.

Honda Accord

Dual microphones - one located in the headliner near the overhead console and the other near the rear overhead light module - pick up low-end drivetrain frequency noise entering the cabin. This audio signal is sent to the Active Noise Control electronic processor, which creates and sends a precisely timed "reverse phase" audio signal to a special amplifier. In turn, the amplifier drives the door speakers to cancel the original noise signal.

ANC dramatically reduces the booming sound of the exhaust for passengers in the front as well as rear seats. In the frequency range below 100 Hertz, ANC results in a remarkable 10 dB reduction in noise level.

Power Moonroof
The Accord Sedan and Coupe’s available power moonroof is wider than in the previous generation Accord’s and now incorporates a one-touch open/close feature. (Please see Body & Chassis tab for more information.)

Auto Up/Down Front Windows
Available for the first time in Accord EX models, both the driver and front passenger windows have auto up/down capability. (Please see Body & Chassis tab for more information.)

Honda Accord

Auto-Dimming Mirror
An auto-dimming rearview mirror is standard on Accord EX-L models for the first time. The rearview mirror automatically dims to an anti-glare setting when bright headlamps are detected behind the vehicle.

Door Lock Buttons
In the previous-generation Accord, the inside door-lock button was located at the rear of the front door next to the B-pillar. For convenience, it is now located in within close proximity to the door handle. This both improves the appearance of the doorsill and provides easier operation.

Auto Lock/Unlock
All 2009 Accord models include a customizable Auto Lock/Unlock feature that can add a sense of security for vehicle occupants.

Choices for automatic door locking include:

  • Doors lock when vehicle speed reaches 9 mph.
  • Doors lock when gearshift is moved from Park.
  • Automatic door locking function off.

Choices for automatic door unlocking include:

  • Driver’s door unlocks when engine is turned off.
  • All doors unlock when engine is turned off.
  • Driver’s door unlocks when vehicle stops and the gear shift is moved to Park (automatic transmission models only).
  • All doors unlock when vehicle stops and the gear shift is moved to Park (automatic transmission models only).
  • Automatic door unlocking function off.
Honda Accord

In all cases, the doors are designed to automatically unlock when there is a sufficient shock to the body to deploy the airbags while the ignition is turned on.

Cargo Carrying Versatility
A full range of convenient storage options exist for the driver and passengers in both the Accord Sedan and Coupe. These include:

Accord Sedan and Accord Coupe

  • Two front beverage holders located in center console
  • Center console (two-level in EX, EX-L and V-6 models)
  • Two rear cup holders (located in center armrest for Sedan, side panels for Coupe)
  • Folding rear seat
  • Front door bins
  • Two seatback pockets
  • Covered forward box
  • Ski pass-through

Door Trim

Honda Accord

A new type of door-sash trim is used for the area of the A-pillar and B-pillar that are visible when the door is open. Instead of a color-matched tape surface (typical for the mainstream midsize car segment), the 2009 Accord uses a plastic garnish that is projected to have higher durability over the years. Likewise the exterior B-pillar uses a high-quality plastic garnish that replaces the tape trim used on the previous-generation Accord. The result is a neater appearance that will last longer.

Colors

Ivory, Gray and Black interiors are offered on 2009 Accord Sedan, while the Accord Coupe comes with a choice of Ivory or Black interior.

All interior color schemes are available in both cloth and leather upholstery.

Honda Accord
  • Ivory provides a light, warm, rich feeling that is complimented by wood-grain (EX Sedan) and silver-tone (Coupe) trim finishes on the instrument panel center pad and the door panels.
  • LX Sedan interiors feature exclusive gunmetal interior trim finishes on door panels and instrument panels.
  • Gray is modern and stylish, and available only on Accord Sedan.
  • Black is deep and cool, with silver-tone accents on the instrument panel center pad and the door panels.

Powertrain

A total of four engines are available in the 2009 Accord family - a pair of inline four-cylinder engines and two V-6 engine choices. The base engine is a 2.4-liter i-VTEC inline four-cylinder powerplant in the LX Sedan and LX-P Sedan. With 177 horsepower, this engine delivers an increase of 7% in horsepower compared to its predecessor, while operating on regular unleaded fuel (as before). The highly-efficient power plant meets Partial Zero Emissions Vehicle (PZEV) (AT only) or ULEV-2 emissions standards* and delivers EPA-estimated City/Highway fuel economy of 21/311 mpg (Sedan AT). In total, the new Accord’s base engine is more powerful, cleaner and more fuel-efficient2 than the engine it replaces.

Honda Accord

In the Accord LX-S Coupe and all EX and EX-L models, an even more powerful inline four-cylinder engine is standard. With a high-flow muffler and reprogrammed Powertrain Control Module (PCM), the 2.4-liter inline four-cylinder generates 190 horsepower at 7000 rpm and 162 lb-ft. of torque at 4400 rpm. Though it’s by far the most powerful four-cylinder engine ever offered in a North American Accord, this powerplant is designed to run on regular unleaded fuel, and also meets PZEV (AT only) or ULEV-2 emissions standards.* With a 5-speed automatic transmission, it also delivers EPA-estimated City/Highway fuel economy of 21/31(1) mpg (Sedan AT) using the new 2009 EPA methodology. That makes it just as fuel efficient as the less-powerful four-cylinder engine found in the LX and LX-P Sedan.

Both four-cylinder engines are certified as PZEV in California, Connecticut, Maine, Massachusetts, New York, Pennsylvania, Rhode Island and Vermont. Fuel economy ratings and horsepower are unchanged, but these engines comply with tougher PZEV requirements, in part, by virtue of a special i-VTEC system that leaves one exhaust valve closed in each cylinder at low rpm, and the use of new fuel injector and dual probe spark plugs that improve combustion, in addition to the near-zero evaporative emissions equipment.

Accord Sedan and Coupe V-6 models equipped with 5-speed automatic transmissions are powered by a 3.5-liter i-VTEC V-6 that is the most powerful engine ever offered in a Honda vehicle. It features a new generation of Honda’s advanced Variable Cylinder Management (VCM) variable displacement technology with a special SOHC i-VTEC valvetrain that allows it to operate in three different modes. Depending on driving conditions, the engine operates on three, four or all six cylinders to help boost fuel economy or power as needed.

Honda Accord

With a 16% increase in displacement compared to the previous 3.0-liter Accord V-6, this new powerplant delivers 268 horsepower at 6200 rpm and 248 lb-ft. of torque at 5000 rpm, operating on regular unleaded fuel. That is a 10% increase in horsepower and a substantial 18% boost in torque as compared to the previous V-6.

The Accord V-6 meets PZEV (AT only) or ULEV-2 emissions standards.* Though it is larger and more powerful than any engine ever offered in Accord, the V-6 returns EPA-estimated 19/291 City/Highway fuel economy, using the 2009 EPA methodology. That makes it more fuel efficient than the smaller, less powerful engine it replaces when 2007 and 2009 models are tested using the identical 2009 EPA fuel economy evaluation parameters.

* In states that adhere to California Air Resource Board (CARB) emissions standards. All engines meet federal Tier 2/Bin 5 emissions standards.

The Accord EX-L V-6 Coupe with 6-speed transmission has a unique variant of the Accord V-6 that uses VTEC valve gear without VCM to achieve enhanced low- and midrange performance. This engine has the same peak horsepower and torque as the i-VTEC VCM engine, and meets ULEV-2 emissions standards. It is paired with a close-ratio 6-speed manual transmission for maximum performance and driving control.

Honda Accord

Shared Engine Features

The following engine technologies are shared among all 2009 Accord models unless noted.

i-VTEC (all except Accord V-6 6MT Coupe)
Though the Accord four-cylinder engines and the V-6 with automatic transmission are all called i-VTEC powerplants, it is important to note that the details in each application differ. Honda Honda ’s four-cylinder engines have double overhead camshafts (DOHC) and i-VTEC that is comprised of VTEC + Variable Timing Control (VTC) of the intake camshaft for optimized power production and fuel efficiency. In addition, PZEV variants also idle one of the two exhaust valves in each cylinder at low rpm for enhanced emissions performance. Accord V-6 engines (with the automatic transmission) use a Single Overhead Camshaft (SOHC) design that features i-VTEC with Variable Cylinder Management (VCM) to maximize fuel economy.

Dual-Probe Spark Plugs
The Accord’s 4-cylinder and V-6 PZEV-compliant engine uses special dual-probe spark plugs (a first for Honda in North America) for faster mixture ignition speed and improved combustion stability. With the spark arcing just beyond the relatively large surface of the ground area, the air/fuel mixture is exposed to a larger portion of the spark, which enhances stable combustion.

Drive-By-Wire (DBW) Throttle System™
The Accord’s drive-by-wire throttle system uses smart electronics instead of a conventional cable system to connect the throttle pedal to the throttle butterfly in the intake tract. Besides allowing engineers to program the relationship between throttle pedal movement and engine response, the system offers optimizes engine response to suit driving conditions. The system monitors throttle pedal position, throttle butterfly position, road speed, engine speed and engine vacuum. This information is used to define the throttle control sensitivity.

Honda Accord

Programmed Fuel Injection (PGM-FI)
The Accord’s PGM-FI continually adjusts the fuel delivery to yield the best combination of power, low fuel consumption and low emissions. Multiple sensors constantly monitor critical operating parameters, such as throttle position, intake air temperature, coolant temperature, ambient air pressure, intake airflow volume, intake manifold pressure, exhaust air-fuel ratio and the position of the crankshaft and cams.

Direct Ignition System
All Accord engines use direct ignition, which has a coil unit for each cylinder, positioned within each spark plug’s access bore.

Fuel Injectors
The Accord engine’s fuel injector nozzles reduce the typical size of fuel droplets by 34 percent compared to the 2007 model, which improves atomization and flame propagation inside the combustion chambers. The better atomization enhances combustion and reduces emissions.

High-Efficiency Catalytic Converters
Key contributors to the Accord engine’s excellent emissions performance are its high-efficiency catalytic converters. All engines have their exhaust manifold(s) cast directly into the aluminum alloy cylinder head(s) to reduce weight and position each primary catalytic converter as close as possible to the combustion chambers. A high-efficiency close-coupled converter mounts directly to the exhaust port of each cylinder head for extremely rapid converter activation after engine startup. A second converter is positioned shortly downstream, beneath the passenger compartment floor. Both converters use a new thin-wall design that increases internal reaction area and improves efficiency.

Maintenance Minder System and Tune-Up Intervals

Honda Accord

The Accord’s standard Maintenance Minder system calculates the engine’s tune-up schedule based on driving conditions (tracked by the ECU). When determining proper maintenance intervals, the system minimizes owner guesswork about whether the vehicle is being operated in standard or severe conditions. The Accord’s Maintenance Minder information appears in the odometer display, and indicates when to change the oil, oil filter (every other oil change), air cleaner, transmission fluid, spark plugs and coolant, as well as when to rotate the tires. A tune-up is not required until 100K+/- Miles No Scheduled Tune-ups (may vary with driving conditions. Does not apply to fluid and filter changes. Exact mileage is determined by actual driving conditions. The owner’s manual contains full detail).

Regular Unleaded Fuel Operation
To keep operating costs at a minimum, all Accord models are designed to use relatively less-expensive regular unleaded fuel, thanks to compact 4-valve combustion chambers and precise fuel injection and spark control.

177 Horsepower 2.4-liter Inline 4-cylinder Engine (LX, LX-P Sedan)

Overview
A 2.4-liter DOHC i-VTEC four-cylinder engine that develops 177 horsepower and 161 lb-ft. of torque powers the LX and LX-P Accord Sedans. This clean-running engine meets PZEV (AT only) emissions standards in select states, or Federal Tier 2, Bin 5 standards in all states. It delivers EPA-estimated 21/311 mpg City/Highway fuel economy (Sedan AT).

Engine Block and Crankshaft

Honda Accord

Accord’s 2.4-liter engine has a die-cast aluminum block with a single main-bearing cradle design that creates a rigid assembly to help minimize noise and vibration. Centrifugal spin cast iron cylinder liners provide long lasting durability. Each journal on the forged-steel crankshaft is micropolished to reduce internal friction.

Cylinder Head and Valvetrain
The Accord four-cylinder engine has a lightweight cylinder head that is made of pressure-cast aluminum alloy. A silent-chain drives dual overhead cams and four valves per cylinder. The cam drive is maintenance free throughout the life of the engine.

i-VTEC Valve Control System
The Accord’s 2.4-liter, DOHC, 16-valve i-VTEC engine uses an advanced valve-control system to combine high power output with high fuel efficiency and low emissions. The Accord system combines Variable Timing Control (VTC), which continuously adjusts the intake camshaft phase, with Variable Valve Timing and Lift Electronic Control (VTEC), which changes valve lift, timing and duration of the intake valves.

At low rpm, the VTEC intake valve timing and lift are optimized for rapid swirl-pattern cylinder filling. As engine rpm builds past 5000 rpm, the VTEC system transitions to a high-lift, long-duration intake cam profile for superior high-rpm engine power.The "intelligent" portion of the system is its ability to continuously vary the timing of the intake cam relative to that of the exhaust camshaft. This helps boost power and also provides a smoother idle (allowing idle speed to be reduced). The intake cam timing is varied based on input from sensors that monitor rpm, timing, throttle opening, cam position and exhaust air-fuel ratio. The result is increased fuel economy and lower NOx emissions.

Honda Accord

PZEV Version
A PZEV version of the 177- and 190-horsepower four-cylinder engines is sold in California, Connecticut, Maine, Massachusetts, New York, Pennsylvania, Rhode Island and Vermont. The principal differences between the PZEV Accord and the ULEV-2 version sold in all states are single exhaust valve operation at low rpm, special dual-probe spark plugs and remapped Powertrain Control Module (PCM) programming, in addition to the near-zero evaporative emissions equipment. The horsepower, torque and EPA-estimated fuel economy of the PZEV and ULEV-2 engines are identical.

Single Exhaust Valve Operation
The Accord’s 2.4-liter DOHC i-VTEC PZEV-compliant engine has two modes of exhaust valve operation. Below 2500 rpm, only one exhaust valve operates, creating a strong rotational flow in the exhaust gases that creates a "thermal reactor" effect to reduce hydrocarbon emissions. Above 2500 rpm where exhaust flow increases, a hydraulically actuated pin locks the rockers for both exhaust valves together so they operate in unison, following a single cam profile.

190 Horsepower 2.4-liter Inline 4-Cylinder Engine (EX, EX-L Sedan; All Coupes)

Overview

Honda Accord

The 2.4-liter inline four-cylinder engine that powers the EX, EX-L Sedan and LX-S, EX and EX-L Coupe is closely related to the engine in the LX Sedan and LX-P Sedan. The 190-horsepower inline four-cylinder meets ULEV-2 in all states, and PZEV (AT only) emissions standards in select states. Like the 177-horsepower engine, the 190-horsepower engine’s PZEV variant has single exhaust valve operation at low rpm, dual-probe electrode spark plugs and special PCM mapping.

The key feature that allows this engine to make an additional 13 horsepower and 1 lb-ft. of torque compared to the 177-horsepower four-cylinder engine is a special exhaust system with larger diameter tubing and a variable-valve silencer design that nets a 31% increase in flow relative to the previous generation Accord four-cylinder system. Despite its performance advantage, this engine delivers the same EPA-estimated 21/311 City/Highway fuel economy (Sedan AT) as its less powerful counterpart. Inside the interior of 190-horsepower Accord models, an Active Noise Control system (ANC) helps reduce certain undesirable sound frequencies for greater passenger comfort. (Please see the Interior tab for more information.)

268 Horsepower 3.5-liter i-VTEC V-6 (EX V-6, EX-L V-6 Sedan; EX-L V-6 Coupe)

Overview
The 3.5-liter SOHC i-VTEC V-6 engine available in the Accord Sedan and Coupe is the largest and most powerful engine ever offered in a Honda passenger car. It builds on technologies that have been developed and refined on previous Honda powerplants. With its 60-degree V-angle, the Accord’s V-6 engine is inherently very smooth and has compact overall dimensions that allow efficient packaging within the vehicle. The V-6 with automatic transmission incorporates a new-generation of i-VTEC technology that boosts fuel efficiency using Variable Cylinder Management (VCM).

Engine Block and Crankshaft

Honda Accord

The Accord’s available V-6 has a die-cast lightweight aluminum alloy block with cast-in-place iron cylinder liners. Made with a centrifugal spin casting process, the thin-wall liners are high in strength and low in porosity. The block incorporates a deep-skirt design with four bolts per bearing cap for rigid crankshaft support and minimized noise and vibration. Both the block and caps are heat treated for greater strength.

Cylinder Heads/Valvetrain
Like other Honda V-6 powerplants, the Accord V-6 cylinder heads are a single-overhead-camshaft design, with the cams driven by the crankshaft via an automatically tensioned toothed belt. Made of low-pressure cast, low-porosity aluminum, each cylinder head incorporates an integrated exhaust manifold to reduce parts count, improve flow and optimize the location of the close-coupled catalyst on each cylinder bank.

i-VTEC with 3-stage Variable Cylinder Management™ (VCM™)
The Accord’s available SOHC V-6 with automatic transmission includes i-VTEC with VCM. With the boost in fuel efficiency attributable to VCM, the larger and more powerful Accord V-6 with automatic transmission actually gets better fuel economy than its smaller, less powerful predecessor when tested with the same methodology. Using the EPA’s new 2009 methodology, the Accord V-6 Sedan returns EPA-estimated fuel economy of 19/29 City/Highway. That is an increase over the previous Accord V-6 (18/26 City/Highway) of 1 mpg City/3 mpg Highway, when both vehicles are compared with the same 2009 methodology.

Honda Accord

VCM Operation
To help improve the fuel efficiency of the V-6 engine available with the 5-speed automatic transmission, a new generation of Honda’s VCM is used. This is the first application of VCM on a non-hybrid Accord model. Unlike previous VCM systems that switched between three- and six-cylinder operation, the Accord’s system can operate on three, four or all six cylinders.

During startup, acceleration or when climbing hills - any time high power output is required - the engine operates on all six cylinders. During moderate speed cruising and at low engine loads, the system operates just one bank of three cylinders. For moderate acceleration, higher-speed cruising and mild hills, the engine operates on four cylinders.

With three operating modes, the VCM system can finely tailor the working displacement of the engine to match the driving requirements from moment to moment. Sin Sin ce the system automatically closes both the intake and exhaust valves of the cylinders that are not used, pumping losses associated with intake and exhaust are eliminated and fuel economy gets a further boost. The VCM system combines maximum performance and maximum fuel economy - two characteristics that don’t typically coexist in conventional engines.

Honda Accord

VCM deactivates specific cylinders by using the VTEC (Variable Valve-Timing and Lift Electronic Control) system to close the intake and exhaust valves while simultaneously the Powertrain Control Module cuts fuel to those cylinders. When operating on three cylinders, the rear cylinder bank is shut down. When running on four cylinders, the left and center cylinders of the front bank operate, and the right and center cylinders of the rear bank operate.

The spark plugs continue to fire in inactive cylinders to minimize plug temperature loss and prevent fouling induced from incomplete combustion during cylinder re-activation.

The system is electronically controlled, and uses special integrated spool valves that do double duty as rocker-shaft holders in the cylinder heads. Based on commands from the system’s electronic control unit, the spool valves selectively direct oil pressure to the rocker arms for specific cylinders. This oil pressure in turn drives synchronizing pistons that connect and disconnect the rocker arms.

The VCM system monitors throttle position, vehicle speed, engine speed, automatic-transmission gear selection and other factors to determine the correct cylinder activation scheme for the operating conditions. In addition, the system determines whether engine oil pressure is suitable for VCM switching and whether catalytic-converter temperature will remain in the proper range. To smooth the transition between activating or deactivating cylinders, the system adjusts ignition timing, drive-by-wire throttle position and turns the torque converter lock-up on and off. As a result, the transition between three-, four-, and six-cylinder operation is unnoticeable to the driver.

Active Control Engine Mount (ACM) and Active Noise Control (ANC)

Honda Accord

The ACM system is used to minimize the effects of engine vibration as the VCM system switches cylinders on and off. Sensors alert the Electronic Control Unit (ECU) to direct ACM actuators positioned at the front and rear of the engine to move to cancel engine vibration. Inside the interior of the Accord, the ANC system works in cooperation with the ACM system to further reduce any sound relating to the function of the VCM system. (Please see the Interior tab for more information.)

V-6 High-Flow Exhaust System
The Accord V-6 has a completely new exhaust system to accommodate its larger displacement and increased power output. Tubing diameter has been increased and new dual silencers are used. In total, the changes provide a 38% increase in exhaust flow compared to the previous V-6 system.

3.5-liter VTEC V-6 (Manual Transmission EX-L V-6 6MT Coupe)

Overview
The Accord V-6 Coupe with 6-speed manual transmission uses a unique version of the 3.5-liter V-6. In place of the i-VTEC cylinder heads that incorporate Variable Cylinder Management (VCM) technology for enhanced fuel economy, the performance-oriented 6-speed V-6 Coupe has VTEC cylinder heads that operate all six cylinders under all driving conditions. The engine switches between two different intake valve profiles based on the operating conditions to deliver superior low- and mid-range power, while achieving the same peak 268 horsepower and 248 lb-ft. torque figures found in the automatic transmission version with VCM. The engine also features a variable intake manifold (constructed of lightweight magnesium) to improve low- to mid-range torque.

Honda Accord

VTEC® (Variable Valve Timing and Lift Electronic Control)
VTEC® operates the engine’s 12 intake valves in two distinct modes. At low engine speeds, the intake valves follow low lift and relatively short duration cam profiles. At high engine speeds the valves switch to high-lift, long-duration mode to deliver the best volumetric efficiency. The V-6 with 6-speed manual transmission has a VTEC changeover point that occurs at approximately 5000 rpm.

Intake and Exhaust Tuning
The intake and exhaust systems on the Accord Coupe V-6 with six-speed manual transmission feature exclusive intake and exhaust tuning for sporty sounding performance. The intake is designed to resonate a unique performance sound at mid and high rpms, while the exhaust is designed to convey a low, powerful note at low to mid rpm.

Transmissions

5-Speed Manual Transmission
A lightweight, compact 5-speed manual transmission is available with either the 177- or 190-horsepower Accord four-cylinder engine. Housed in a rigid die-cast aluminum case, the transmission uses multi-cone synchronizers on first through fourth gears that contribute to a smooth, fluid shift feel. A single plate clutch with a diaphragm-type spring provides smooth, progressive engagement combined with low pedal effort.

Honda Accord

Close-Ratio 6-Speed Manual Transmission
While most Accord V-6 models have a 5-speed automatic transmission, the EX-L V-6 Coupe is also available with a close-ratio 6-speed manual transmission. This short-throw unit is designed to take advantage of the high power and torque of the new Accord V-6 engine and give enthusiast drivers maximum control.

Substantially lighter than the automatic transmission, the 6-speed manual features a high-pressure die-cast aluminum-alloy transmission housing to save weight. High-strength steel gears are used, and the shafts are hollow, netting a further reduction in weight.

Closely spaced ratios help provide stronger acceleration by keeping engine revs up closer to the engine’s horsepower peak. A reverse lockout feature prevents the transmission from accidentally being shifted into reverse while the car is moving forward.

The Accord’s manual transmission is matched with a compact clutch unit that is self-adjusting for consistent pedal stroke and load throughout its service life. A dual-mass flywheel cuts down the transfer of engine vibration into the cabin and provides increased comfort during shifting and helps to reduce noise.

5-Speed Automatic Transmission

Honda Accord

Accord four-cylinder and V-6 models are available with 5-speed automatic transmissions with Grade Logic Control. Four-cylinder engines have a compact three-shaft transmission design that is engineered for smooth operation and fuel efficiency. To accommodate the large displacement and high power output of the Accord V-6 engine, a four-shaft, 5-speed automatic transmission related to the transmission used in the Honda Odyssey is used.

Accord’s Powertrain Control Module (PCM) manages overall powertrain operation, and provides precise management of the interaction between automatic transmission and engine. This integrated control strategy makes for smoother shifts with reduced shift shock. VCM engines are equipped with a long torsional control damper to helps enhance overall transmission smoothness.

Different transmission gear ratios are used for the 177-horsepower and 190-horsepower four-cylinder engines. To take full advantage of the 190-horsepower engine’s added high-rpm power, its 5-speed automatic transmission has lower second-, third- and fourth-gear ratios (higher numerically). This provides an added boost to acceleration and responsiveness. The first- and the fifth-gear ratios are common among all four-cylinder engines, resulting in an efficient and quiet cruising rpm at higher speeds.

Honda Accord

Grade Logic Control
To reduce gear "hunting" and unnecessary shifting, Grade Logic Control and Shift Hold Control systems are integrated into the shift programming of Accord automatic transmissions. Grade Logic Control alters the 5-speed automatic’s shift schedule, reducing shift frequency while traveling uphill or downhill. Using inputs monitoring throttle position, vehicle speed and acceleration/deceleration, Grade Logic compares the operating parameters with a digital map stored in the transmission computer. When the system determines the Accord is on a hill, the shift schedule is adjusted to automatically hold the transmission in a lower gear for better climbing power or increased downhill engine braking.

Shift Hold Control
Shift Hold Control prevents upshifts to higher gears (fourth and fifth) in repeated winding-road situations where the throttle is quickly released and the brakes are applied. This reduces disturbance to the chassis when entering a corner, and ensures strong power is available without a downshift. Shift Hold Control improves throttle responsiveness and reduces unnecessary shifting on curving roads.


Chassis

The 2009 Accord chassis was developed to maximize driving enjoyment as well as passenger comfort. It features highly developed double-wishbone front and new multi-link rear suspension systems, along with 4-wheel disc brakes and new Variable Gear Ratio (VGR) steering.

Honda Accord

The 2009 Accord offers a solid, agile and tight feeling with well-controlled roll and pitch characteristics. It all results in a precise and nimble-handling vehicle that intuitively connects with the driver’s commands. As a result, every 2009 Honda Accord is both refined and fun to drive.

Low Center of Gravity
Careful attention to detail resulted in a reduced height for the engine’s center of mass (10mm lower for the V-6 engine and 8.5mm lower for the inline 4-cylinder engine). The center of gravity for the entire vehicle was also lowered by 10mm. To further flatten the Accord’s handling in the turns, the roll-centers (the theoretical points around which the vehicle body "rolls" during cornering) were raised incrementally. Combined, these changes result in less body roll and increased passenger comfort. The flatter roll characteristics also improve tire contact patch during hard cornering, increasing grip and lateral acceleration.

Front Suspension
The 2009 Accord’s front suspension is a modified version of the double-wishbone system used on the 2007 Accord, with stabilizer bars, spring and damping rates optimized to provide the best combination of ride and handling. Front lower control arms are forged steel and connect to a stamped steel box-section sub frame. A stamped-steel upper control arm complements a forged-steel knuckle, and nitrogen gas-filled coil-over dampers are used. A key improvement to the 2009 Accord’s front suspension geometry is increased anti-dive under braking. This affords occupants a more stable feeling under severe braking conditions.

Honda Accord

Front Suspension Tower Brace
A tubular steel front suspension tower brace is standard on all Accord models except the base 177-hp Accord LX. It adds chassis stiffness to accept the additional torque and increased grip of the 190-hp 4-cylinder and V-6 models.

Rear Suspension
The 2009 Accord utilizes a new compact multi-link rear suspension. Each side features a nitrogen gas-filled coil-over damper, a newly designed stamped steel upper A-arm, two tubular steel lower links, a single toe-control link, and an aluminum knuckle. The arms and links are mounted to a floating sub frame to reduce road noise, vibration and harshness (NVH).

The body structure around the suspension is stiffer, permitting more ideal tuning of the suspension. Compared to the previous generation Accord, the 2009 model’s rear suspension has 40% greater lateral rigidity. The new rear suspension geometry enhances ride comfort and overall handling and braking.

Honda Accord

Reduced NVH
In addition to the front floating sub-frame, a floating tubular and stamped steel rear-suspension sub-frame, isolated by specially tuned bushings, also helps isolate the body from road NVH on all 2009 Accord models.

4-Cylinder and V-6 Engine Mount System
The 2009 Accord has a new engine mount system to further reduce engine noise, vibration and harshness (NVH) and to improve powertrain isolation, ride smoothness and steering response. The new side-mount system reduces low frequency vibration compared to the previous-generation Accord arrangement.

The new engine mount system also provides a more linear steering feeling. When the driver turns the steering wheel, the body and the engine now move more precisely together, contributing to enhanced steering directness. Additionally, when driving over choppy roads the engine and body move in the same direction - providing a more composed and refined ride quality.

4-Wheel Disc Brakes with Electronic Brake-force Distribution (EBD) and Brake Assist

Honda Accord

For the first time in Honda Accord history, every Accord Sedan and Coupe model includes 4-wheel disc brakes with EBD and brake assist. The Accord brake system uses single-piston calipers front and rear, and is designed to provide confident, secure stops. The system is all new and features the following upgrades and improvements compared to the 2007 Accord:

  •  The master cylinder has a high-rigidity mount for a more responsive and precise pedal feel.
  • An increased brake pedal ratio (2.9:1 for 2009 vs. 2.6:1 for the previous generation Accord) increases braking force without raising pedal effort.
  • The parking brake uses a variable link that permits full application of the parking brake with a shorter handle stroke.
  • A lighter vacuum booster unit and a smaller and lighter VSA unit help reduce vehicle mass.

Active Safety

Honda Accord

Active safety features on the 2009 Accord Sedan and Coupe include an Anti-lock Braking System (ABS), Vehicle Stability Assist (VSA), EBD and brake assist. Of particular note is that for the first time all Accord models now have VSA as standard equipment. VSA is an electronic stability control system that measures lateral acceleration, steering wheel angle, wheel speeds and yaw rate, and then modulates individual brakes and engine power to help the driver retain directional control of the vehicle.

Variable Gear Ratio (VGR) Steering
The 2009 Accord’s new VGR steering system uses a variable mechanical ratio that provides solid on-center feel and intuitive responsiveness.

In a traditional rack and pinion steering system, a helical pinion gear on the steering shaft meshes to a toothed rack that is attached to steering links that control the front wheels. When the steering gear turns, it pushes the rack - and thus the wheels - either left or right at a constant ratio. But in the 2009 Accord’s VGR system, the teeth on the rack are closer together near the center and farther apart near the sides. Simply put, when the driver turns the wheel only a small amount - such as when making a lane change on the freeway - the wheels turn very little. But when a large steering input is made - such as when maneuvering in a tight parking garage - the wider spacing of the teeth at the ends of the rack deflect the wheels proportionally more quickly. The result is high precision at highway speeds and quick maneuverability at low speeds.

Honda Accord

The 2009 Accord steering requires 2.56 turns lock-to-lock compared to 2.98 turns on the previous generation Accord. This quickness is more reminiscent of a sports car than a typical mainstream sedan.

Turning Radius
Both the 2009 Accord Sedan and Coupe feature a tighter turning radius for improved low-speed maneuverability. The turning radius is 18.9 ft. for the Sedan and 18.21 ft. for the Coupe. This is impressive considering that the 2009 Accord is a larger vehicle with a longer wheelbase.

Wheels and Tires
The larger standard wheels and tires on the 2009 Accord Sedan and Coupe significantly enhance the car’s appearance, while increasing tire contact area for enhanced grip during acceleration, cornering and braking.

Honda Accord

All Accord Sedan models have either 16- or 17-inch wheels, and all Coupe models have either 17- or 18-inch wheels. The original-equipment tires include Dunlop for the 16-inch and Michelin for 17-inch applications on Accord Sedan, and all-season Michelin tires for the 17- and 18-inch applications on the Accord Coupe.

The spare tire is a space- and weight-saving T135/80D16 101M temporary unit for both Sedan and Coupe. It is trunk mounted under the carpeted floor.

Tire Pressure Monitoring System (TPMS)
Every 2009 Honda Accord includes a TPMS. Please see the Safety section for more information.

Safety

Honda seeks to provide a high level of occupant and pedestrian protection in all of its cars and trucks through a comprehensive approach to vehicle safety. This process, which honors the company’s Safety for Everyone initiative introduced in 2003, benefits all new Honda vehicles - regardless of size or price - while also increasing compatibility with other types of vehicles in a collision.

Honda Accord

Consistent with the Safety for Everyone initiative, every 2009 Accord integrates sophisticated safety technology that includes the Advanced Compatibility Engineering™ (ACE™) body structure and dual-stage, dual-threshold driver’s and front passenger’s airbags (SRS); driver’s and front passenger’s dual-chamber side airbags; and side curtain airbags. The ACE body structure enhances frontal collision energy management through a network of load-bearing front frame structures designed to improve the likelihood for two vehicles to connect during a frontal collision in such a way as to absorb more crash energy compared to a conventional design.

Advanced Safety Technology
Inside, every Accord incorporates newly-designed side-curtain airbags and dual-chamber front- side airbags with a passenger-side Occupant Position Detection System (OPDS), along with active front head restraints that are designed to help reduce the severity of neck injury in the event of a rear collision. Additional standard safety features include dual-stage, dual-threshold front airbags with a passenger-side Occupant Position Detection System (OPDS), an Anti-lock Brake System (ABS) with brake assist, front seatbelts with pre-tensioners and load limiters, and pedestrian safety design in the front of the vehicle. Driver and front passenger seatbelt reminders and daytime running lights are also standard equipment.

Honda Accord

Advanced Compatibility Engineering™ (ACE™) Body Structure

Honda Accord

At the heart of every new Accord is an exceptionally strong foundation based on the latest version of Honda’s Advanced Compatibility Engineering (ACE™) body structure technology. The revolutionary ACE system makes the new Accord highly effective at absorbing the energy of a frontal crash and helps minimize the potential for under-ride or over-ride situations that can happen during head-on or offset frontal impacts with a significantly larger or smaller vehicle. Using a sophisticated computer-assisted design process, the ACE system creates a network of fully integrated load-bearing elements that help attenuate peak impact forces by more evenly distributing them across a relatively large area in the front of the vehicle.

Unlike most conventional designs that direct frontal crash energy only to the lower load-bearing structures in the front end, the ACE system actively channels frontal crash energy to both upper and lower structural elements, including the floor frame rails, side sills and A-pillars. By creating specifically engineered "pathways" that help distribute these frontal impact forces through a greater percentage of the vehicle’s total structure, the ACE system can more effectively route them around and away from the passenger compartment to help limit cabin deformation and further improve occupant protection. Integral to the ACE concept is its unique front polygonal main design structure.

Structural Enhancements

Honda Accord

Comprehensive structural enhancements can be found throughout the new Accord unit body, which now contains 48% high-strength steel. The main longitudinal frame rails have been redesigned and repositioned above the floor panel rather than below to further improve the car’s ability to withstand severe side-impacts, while new and more robust rear structural elements add rigidity and help the Accord meet the stringent new FMVSS 301 regulations.

Pedestrian Safety Design
Structures in the front of the Accord are designed to help absorb energy in the event of a collision with a pedestrian. Research by Honda shows that the following features can dramatically improve a pedestrian’s chance of survival if struck by a moving vehicle.

Key pedestrian safety features:

  • Hood is designed to deform if contact is made with either an adult or a child pedestrian
  • Sufficient clearance exists between the hood and hard engine parts
  • Windshield base has a boxed frame structure for efficient impact energy absorption
  • Energy-absorbing fender mounts and supports
  • Deformable windshield wiper pivots
  • Deformable hood hinge

Offset Rear Collision
The new FMVSS 301 regulation is more severe than the previous standard. This regulation began its phase-in during September 2006 and must be applied to all production vehicles after September 1, 2009. In the new requirements for the FMVSS 301 standard, a 1,360 kg (2,992 lbs.) deformable barrier strikes 70% of the vehicle’s width at 50 mph. In contrast, the previous FMVSS 301 used a 1,814 kg (3,991 lbs.) flat rigid barrier that struck the full width of the vehicle at 30 mph. The new standard requires more body energy absorption than before. It is Honda’s strategy to offer this high level of rear impact protection on the Accord before it is mandated by the NHTSA.

Honda Accord

Standard Vehicle Stability Assist™ (VSA ®) with Traction Control and Brake Assist
Vehicle Stability Assist (VSA) is an Electronic Stability Control system that works in conjunction with the Accord’s drive-by-wire throttle and its 4-channel ABS systems to enhance controllability while the vehicle is accelerating, braking, cornering or when the driver makes a sudden maneuver. VSA functions by applying brake force to one or more wheels independently while also managing the throttle, ignition and fuel systems to help the vehicle maintain the driver’s intended path of travel.

The VSA system constantly analyzes data from seven sensors that monitor wheel and vehicle speed, steering input, lateral G forces and yaw rate. It compares the driver’s control inputs with the vehicle’s actual response. Whenever the actual response falls outside of a predetermined acceptable range, VSA intervenes with a corrective action.

For instance, if VSA detects an oversteer condition, the system may apply braking force to the outside front and rear wheels to counteract the unintended yawing effect. In the event of understeer, VSA may apply braking to the inside rear wheel while reducing engine power to help return the car to its intended course. VSA also provides a limited-slip differential effect for the front wheels by applying braking force to a slipping wheel, thereby redirecting driving force to the wheel with more traction.

Emergency Braking

Honda Accord

Another key VSA function is recognizing emergency braking situations and almost instantly applying added braking force. This brake assist feature is controlled by a special logic in the system that determines when the pedal stroke and speed exceed a typical range - as they would in a panic stop.

At that point, the VSA modulator pump increases braking pressure while the pedal is still being pressed to ensure maximum stopping force, an action that helps shorten braking distance as much as possible.

VSA is calibrated to function in a near-transparent manner, and in many cases a driver will not even be aware of its operation. However, anytime the system is enhancing vehicle stability, an indicator light flashes in the instrument cluster. While the driver can deactivate the VSA stability enhancement and traction-control functions via a switch on the instrument panel, ABS remains fully operational at all times.

Advanced 4-Channel ABS with Electronic Brake Distribution
A new and enhanced anti-lock braking system has been developed for the 2009 Accord. This sophisticated 4-channel/4-sensor anti-lock package replaces the system found on the 7th generation Accord.

Honda Accord

All 2009 Accord models, regardless of engine or trim level, are fitted with 4-wheel disc brakes that have vented front rotors and solid rear rotors. (Please see Chassis tab for more information.) Thanks to a more rigidly mounted master cylinder, the 2009 Accord’s brake pedal has a firmer feel and a shorter activation stroke. The new ABS system also incorporates Electronic Brake Distribution (EBD) circuitry that automatically proportions force based on the vehicle’s weight distribution.

Dual-Stage, Dual-Threshold Front Airbags
Both the driver and front passenger are protected by advanced front airbags that incorporate dual-stage and dual-threshold activation technology. These two features work together in the event of a deployment while helping minimize injuries that can sometimes be caused by the airbags themselves. Honda’s sophisticated dual-stage, dual-threshold system is designed to optimize the deployment rate to match both the speed and severity of a crash event. The control logic also takes several other factors into consideration, including the relative seat position of the driver and the weight of the front seat passenger, as well as whether the seat belts are in use at the time.

Honda Accord

During a lower-speed collision, or if the seat is too close to the steering wheel, the inflators in the driver’s frontal airbag will activate sequentially to help mitigate the initial force. In a high-speed collision, or if the seat is positioned farther back, both igniters are triggered simultaneously for full and rapid inflation. The passenger-side frontal airbag is designed to operate in a similar manner, however a sensor under the passenger seat calculates whether the weight on the lower cushion meets a NHTSA-specified minimum value. If it doesn’t, the airbag is deactivated, as indicated by a light on the instrument panel.

Like other Honda vehicles, the driver’s front airbag is located in the steering wheel while the passenger airbag is located on the top of the dash. When deployed, the passenger airbag inflates upward and then rearward to maximize its protective potential while reducing the likelihood of injuries being caused by the activation process itself.

Side-Curtain Airbags
Standard side-curtain airbags provide enhanced head protection for outboard occupants of the front and rear seats in all 2009 Accord models. A new design for Honda Honda , the Accord side-curtain airbag design first inflates a main chamber, then a connected sub chamber. This design allows the main chamber to remain inflated for a slightly longer time following a crash. Inputs from side impact sensors and a central sensor are used to determine when to deploy the side curtain airbags.


Advanced Dual-Chamber Front-Seat Side Airbags

Honda Accord

All 2009 Accord models are fitted with front-seat side airbags featuring a new dual-chamber design that offers enhanced protection for the torso and pelvis in case of a severe side impact. Replacing the previous single-chamber airbags, these new dual-chamber units are comprised of a larger upper chamber that provides improved protection for the chest area as well as a smaller lower chamber that focuses coverage on the lower-back/hip area. A single inflator unit fills both chambers. These new dual-chamber airbags are significantly more effective in helping minimize the potential for injuries being caused by impacts from larger vehicles, such as a side impact involving a truck or SUV.

Front Seatbelts with Pretensioners and Load Limiters
The front seatbelts in all 2009 Accord models are equipped with pretensioners and load limiters to help minimize injury potential in a frontal collision. When an impact occurs, the pretensioner tightens the seatbelt (shoulder and lap) to help hold the seat occupant firmly in position. Each front seatbelt retractor incorporates a load limiter that works in conjunction with the pretensioner. In response to the occupant’s input, the load limiter functions by permitting a small amount of controlled seatbelt slack shortly after the pretensioner is activated to limit the peak restraining forces, reducing the potential of serious injury. The front seatbelts in all Accords also feature adjustable shoulder anchors. Three-point seatbelts are standard in all three rear seating positions.

Active Front Head Restraints

Honda Accord

Each of the Accord’s front seats are fitted with an innovative active head restraint designed to help reduce the severity of neck injuries in the event of a rear impact. The head restraint is mechanically connected to a lumbar plate located inside of the seatback via special links. If a rear impact takes place, the passenger’s body is pushed against the seatback. That action causes the head restraint to move forward in a carefully prescribed arc. The effect of this motion helps equalize the impact forces being transmitted to the head, neck and spine throughout the collision as the occupant’s head moves backward. Effectively managing and evenly disbursing these energy spikes is a critical factor in helping minimize the potential for injuries.

Adjustable Rear Head Restraints for All Seating Positions
The rear seats in both the Accord Sedan and Coupe feature individually adjustable head restraints for all three passenger positions.

Lower Anchors and Tethers for CHildren (LATCH)
The outboard rear seating positions in all 2009 Accord models are fitted with Lower Anchors and Tethers for CHildren (LATCH) that provide a simple and secure method of installing up to two compatible child safety seats. Alternately, the center position incorporates an upper tether that makes it possible to fit a single child safety seat in either the Sedan or Coupe. When a child seat is in the center position, additional child seats may not be used in the outboard positions.

Honda Accord

Tire Pressure Monitoring System (TPMS)
All Accord models are fitted with a new direct Tire Pressure Monitoring System (TPMS) that alerts a driver whenever the air pressure in one or more of the vehicle’s tires decreases significantly below the recommended level. Using four sensors (one in each tire) TPMS monitors and transmits information on tire air pressure to the Accord’s ECU. When the pressure in one or more tires drops to a potentially critical level, it causes a low tire pressure indicator (located in the instrument cluster) to illuminate.
