2015 Chevrolet Silverado HD

Posted on by +  

With the roaring applause still ringing from the recent debuts of the new Silverado 1500 , Tahoe and Suburban , Chevy has also revealed a pretty heavy revamp for the 2015 HD trucks.

It seems the welcome reception to all the other new bow-tie trucks means that the 2014 model year will be very short: GM pushed up the HD release so that all the factories can start gearing up for the hugely-improved 2015 model year.

The Silverado HD’s updates are actually much deeper than a facelift, with the largest changes coming from the way the truck body is mounted to the chassis. Chevrolet is using a new type of welding process that is claimed to bring large increases in all rigidity measurements, cabin quietness and ride comfort.

The new nose looks pretty great, actually. Chevy ’s truck styling really seems to be very sharp these days. Projector beam lamps update the nose nicely, and a very dramatic chrome grille has far more shaping and structure to its surfaces.

Improvements to cooling and aerodynamics are hoped to increase highway fuel economy, where these big trucks really start to chug whatever fuel they are using at anything over 65 mph.

Drag is a real issue for these machines, and any HD owner will tell you that an 80 mph cruise with a trailer can switch the usual miles per gallon into gallons per mile.

Other changes include a totally-redesigned cabin, seats, infotainment and the whole vehicle’s electronic architecture. Under the hood, the engines are carryover but have a new engine management that integrates all the towing and stability safety features into its work flow.

What this boils down to for buyers is better economy, higher payload and towing stats, and a cruise control that now claims to be able to maintain a set speed even with a heavy trailer out back. Previous cruise controls for many cars will pop off and fail to keep a speed if doing so might make the engine stall.

So it is truck-a-palooza at Chevrolet this winter. Are buyers swayed by the new looks and vastly superior cabin?

Click past the jump for a closer look at the new sheetmetal, plus all the mechanical specs of the 2015 Chevrolet Silverado 2500HD and Silverado 3500HD.

Exterior

Chevrolet Silverado HD

The new 2015 Silverado HD trucks look better than ever. There are virtually no panels carried over except the windshield and roof, which is a pretty extensive makeover.

The most defining change is to projector beam headlights versus halogen reflectors, which look terrific next to the gaping appearance of theFord Super Duty trucks. The grille’s wide chrome bar is now much larger than before in both length and width, extending out through the headlights for a tough and butch appearance.

The grille is now chopped slightly at all its edges, with a beveled shape that looks premium. The top part of the chrome grille is pretty interesting because it makes more of a crown for the tall HD hoods. Overall, a far more successful nose job than the Ram HD’s unnoticeable styling updates since the 1990s.

To the sides, both the 2500HD and the 3500HD have huge a sculpted boxed wheel flares. They really help the HD trucks look the part of an unstoppable workhorse of the future, and almost seem wide enough for a dually front wheel option as well.

In back, the changes are more subtle, but do add some nice new creases to the tailgate and the rear flares to match the front. Cut-outs in the back bumper corners (a la Xterra) make it easier to climb into the bed when carrying something heavy, but the taillights seem to lack LEDs in the initial press photos.

Interior

Chevrolet Silverado HD

The 2015 Silverado HD trucks are all almost completely transformed by greatly enhanced comfort and technology. The dashboard also looks less bland than before, with a new multi-function steering wheel a particular highlight. Huge, huge improvements inside these big trucks.

The LTZ spec is the one to get, with better everything from carpets to speakers to headliners to seat cloth.

Last week’s review of the 2014 Silverado HD models (so, the current year not these new 2015 trucks) uncovered an alarming gap in the Chevy HD trucks interior roominess versus the best-selling F-Series Super Duty .

The Chevy is down a few inches in hip room, and almost seven inches in shoulder room. Most interior dimensions for such fierce competitors are much closer than this. Generally, anything more than two inches makes a big difference in comfort.

No news from Chevy on the hip or shoulder room measurements, which probably answers the question of whether these stats will grow for 2015. (Shorthand: No, probably not any wider inside).

The similar Suburban and Tahoe gain 2.5 inches of head room and a whopping four inches of legroom versus the current cars, which is another big improvement.
Sharing the best infotainment with the more consumer-focused models means the HD Silverado’s are far more up-to-date and entertaining over the long haul.

Powertrain, Suspension and Brakes

Chevrolet Silverado HD

No big changes under that monster hood. The HD trucks just received the latest engines for 2013, so the current performance will largely continue unchanged for 2015.

Better breathing and cooling is the most notable improvement, which increases the trucks’ already-incredible stamina when towing heavy loads in really extreme hot or cold weather, or altitude.

A gasoline V-8 comes standard and is the normal FlexFuel engine setup that can safely run E85. The middle option is the same V-8 but with hardened and fortified valves and other components to allow a bi-fuel option.

Bi-fuel basically means being able to jump between gasoline and natural gas at the flip of a switch. The HD trucks are not yet sold as full CNG vehicles, but the up-fitting and room for the CNG tank is designed right into the core platform of all models.

Lastly, the legendary DuraMax V-8 chug chug chugs into 2015 with only detail tweaks to smoothness and a new standard final drive ratio that delivers increased payload and tow maximums.

The 3500HD can now tow a barely-believable 19,600 pounds on the hitch, or 23,200 pounds on a fifth wheel trailer that hooks into the bed of the trucks.

2015 Chevrolet Silverado HD - Tow and Payload Ratings

  • Maximum available payload is 7,374 pounds, the best for any HD pickup, up from 7,222 pounds.
  • Maximum available conventional towing is 19,600 pounds with the available factory hitch, up from 18,000 pounds and also best in class.
  • Maximum available fifth-wheel towing is 23,200 pounds, up from 22,500 pounds.

Competition

Ford F-Series Super Duty

Ford F-Series Super Duty

The Ford is looking quite good these days, despite sharing the nose and headlight design that is so popular with municipal fleets. Headlights that look more at home behind a snow plow are a selling point for the big Super Duty, which is slowly sending all of its butch design cues like the grille and door glass cutout to the cheaper F-150 models.

The F-250 also offers a bi-fuel setup with two tanks, one for gasoline and one for CNG. The F-250 is down on power and sprint pace versus the Silverado HD, even with the latest PowerStroke and Coyote engine families.

Ram HD

Ram Heavy Duty

The Ram Heavy Duty gains new LED light accents for the headlights, projector beams for the low beams, and LED’s out back for 2014. It also brings an optional air suspension for the rear axle, but this improved ride comfort also limits the Ram’s payload, towing and ground clearance.

One really cool feature available on the Ram Heavy Duty is a backup camera that also has microphones mounted outside the car, so the driver can hear people giving directions when hitching a trailer or loading cargo. This sounds good on a normal sunny day, but is really useful when it is dark, cold and miserable outside - all the times when most people would like to leave the windows up.

Conclusion

Chevrolet Silverado HD

A bit of a question for all the guys and gals who tow anything above 10,000 pounds: what that heck is back there? Most drivers will never know what it is like to pilot a rig of that kind of mass, so Chevy ’s changes to comfort and safety also seriously improve the HD’s ability to get the work done.

The engines are already class-leading, so the only two questions most people will have are: When and How Much?

Details on the truck’s arrival to Chevy dealers and the pricing for the re-designed models are not yet available. Based on the information available, we project an $800 price increase and arrival by early Spring 2014.

  • Built smart, with advanced chassis controls for more confident towing
  • New cabs and interiors for all-day comfort, on the job and on the road
  • Diesel, gas and CNG power available on 2500 and 3500 models

2013-09-26 DETROIT – The new 2015 Chevrolet Silverado HDs are engineered to be stronger, smarter, and more confident than ever.

“Heavy-duty pickups are tools that people use to tow heavy trailers and haul big loads,” said Jeff Luke, executive chief engineer. “A great tool like the new Silverado HD pickup doesn’t just get the job done, it makes the work easier, and helps you feel more confident tackling the really tough jobs.”

Chevrolet Silverado HD

Updates for the 2015 model year include:

  • All-new exterior styling with enhanced cooling air flow, which enables Silverado’s 6.6-liter Duramax turbo diesel and 6.0-liter Vortec V-8 to better maintain full power, even under heavy loads and high ambient temperatures

New exterior design for enhanced cooling, reduced wind noise

Silverado HD’s all-new exterior communicates strength and capability, while also enhancing aerodynamics for improved efficiency and reduced wind noise, It also improves cooling for more consistent power under tough conditions.

"The passion we have for trucks is reflected in every line and powerfully sculpted machined surface of the HD Chevrolet," said Tom Peters, design director. "From the dramatic sculpture of the one-piece structural bumper, to its muscular hood and side profile, the design reflects a function-driven solution."

Chevrolet Silverado HD

The design of the 2015 Silverado HD is as much about brains as brawn. New inlaid doors, which fit into recesses in the body side, help reduce wind noise for a quieter cab. The smallest details of the body, such as the roof and tailgate spoiler, were tuned in a wind tunnel to smooth airflow over the truck for reduced noise and improved aerodynamic efficiency.

Because HD pickups are frequently used for towing under adverse conditions, engineers paid particular attention to airflow for both engine cooling and the engine air intakes. Starting with air inlets sized to reduce drag and improve efficiency, engineers tested cooling airflow in the wind tunnel and on the road to make sure the engines could maintain power on long upgrades at high ambient temperatures. Careful sealing of the front end also ensures that air entering the engine intake remains cool, for optimum performance under tough conditions.

Chevrolet Silverado HD

“It is one thing to generate big power numbers in cool weather, and quite another to maintain power and torque when towing up a long grade on a blistering summer day,” said Luke. “We think customers will appreciate all of the work that went into the cooling for the new Silverado HD when they get a chance to really put it to the test.”

Integrated controls for easier towing

The new Silverado HDs are also designed to bring new levels of confidence to tough towing through further refinement of Silverado’s available Cruise Control, Auto Grade Braking, and Diesel Exhaust Brake. The integration of these features helps the 2015 Silverado HD maintain a set speed up and down grades, even when towing a heavy trailer in mountainous terrain.

“The customer sets the desired speed, and the truck will do the rest – increasing or decreasing power, downshifting to increase engine braking, and engaging the exhaust brake on the diesel engine,” said Luke. “You feel much more confident and in control, because you aren’t constantly working to stay a step ahead of the truck and trailer.”

Chevrolet Silverado HD

To activate the Auto Grade Braking on either gasoline or diesel Silverado HDs, the driver presses and holds the Tow/Haul button in the shifter for three seconds. The transmission will then automatically downshift when needed to enable engine braking to help slow the vehicle.

In addition, on Duramax diesel models, the driver can also engage the Diesel Exhaust Brake, which uses the variable vanes in the turbocharger to smoothly and quietly create additional backpressure in the engine to help slow the vehicle. The combination of the exhaust brake and the automatic transmission downshifts helps the driver maintain the desired speed, even on long, steep highway downgrades.

StabiliTrak with Trailer Sway Control is now standard on all Silverado HDs, including 3500 dually models, providing additional security to the drive.

Built strong, with rugged truck hardware

The foundation of 2015 Silverado HDs is a family of fully boxed frames, which use large cross sections, hydroforming and high-strength steels in key areas. The stiffness of the frames contributes to improved handling and ride comfort, while the strength of the frames enhances payload and towing capability.

The Silverado HDs independent front suspension is specifically engineered for HD pickup use, with forged steel upper control arms and precision machined cast iron lower control arms. Torsion bars are tailored to the weight ratings of the trucks, ad allow easier trim height adjustment to account for the weight of snow plows or other accessories.

Chevrolet Silverado HD

Rear springs are asymmetrical leaf springs, which balance ride and load carrying, and improve control of axle hop. The steel springs, three inches wide, have been proven to perform year after year under the toughest conditions.

Payload and towing capabilities of the 2015 Silverado HD are increased from 2014 models:

  • Maximum available payload is 7,374 pounds, the best for any HD pickup, up from 7,222 pounds.
  • Maximum available conventional towing is 19,600 pounds with the available factory hitch, up from 18,000 pounds and also best in class.
  • Maximum available fifth-wheel towing is 23,200 pounds, up from 22,500 pounds.

Silverado HD is available in more than 150 combinations of cabs, bed lengths, powertrains, drivetrains and axle ratios, enabling customers to spec exactly the right truck for their towing and hauling needs.

The team that created the 2015 Silverado HD went to extremes to deliver a truck that would live up to Chevrolet’s reputation for building the most dependable, longest lasting pickups, said Luke.

For example, GM’s new full-size truck family will undergo more than 6 million miles of durability testing in the torture chambers at the Milford Proving Ground, over the deserts and mountains of Nevada and across the frozen flats of Kapuskasing, Ontario. That’s equivalent to 240 trips around the earth. In addition, the trucks will accumulate more than 7 million real-world miles during final testing, bringing total test miles to more than 13 million.

New cabs and interiors for all-day comfort

The 2015 Silverado HD receives the same updates to the interior, cab structure, and door designs as the new Silverado 1500, which has received positive reviews for its quieter cab and roomier, more comfortable interior.

“Whether they use their truck as their office or travel cross country with a big trailer in tow, owners of HD pickups often spend long days behind the wheel,” said Luke. “The quiet, comfortable, connected interior of the 2015 Silverado HD reflects an intense focus on the way truckers live and work.”

The upright instrument panel, six-gauge instrument cluster and multiple storage options are tailored specifically to the needs of truck customers. Controls are functional, logically placed and easy to operate with work gloves on. For example, the available Integrated Trailer Brake Controller is mounted high on the left side of the instrument panel, where it can be easily adjusted, and it displays Gain on the Driver Information Center in the instrument cluster. The new Chevrolet MyLink, standard on all models except the base work truck, provides easy-to-use connectivity for the job site or the family vacation, with natural voice recognition and enough ports and power outlets to support multiple devices.

The new truck cab is stronger, with nearly two-thirds of the structure made from high-strength steel for a confident feel and improved safety. The cabs feature inlaid doors, which fit snugly

into recesses in the body sides for reduced turbulence and wind rush. Combined with new triple door seals, the doors help create a quieter interior.

The rear doors on crew-cab models are larger, and combined with revised seats, create approximately two inches more rear legroom, and enable easier entry and exit for back seat passengers.

A new double-cab model, which features forward-hinged rear doors, replaces the previous extended cab, and allows easier access to the back seat, especially in tight parking spaces.

Rugged powertrains for gas, diesel, E85 and CNG

The 2015 Silverado HD offers three powertrains specifically tailored for tough tasks and dependable service.

The proven Duramax 6.6L turbodiesel and Allison 1000 six-speed automatic transmission combination will continue to be available on both 2500 and 3500 Silverados.

Rated at 397 horsepower and 765 lb-ft of torque, the Duramax diesel features piezo-actuated fuel injectors for improved performance and efficiency, and a variable vane turbocharger that also acts as an exhaust brake to help control vehicle speed when needed on long downgrades.

The Allison 1000 transmission features a driver shift control with tap up/tap down shifting and a Tow/Haul mode that reduces shift cycling for better control and improved cooling when towing or hauling heavy loads.

The standard engine on all Silverado HDs is a 6.0L Vortec gas V-8 with continuously variable valve timing, matched with a six-speed automatic transmission. It is rated at 360 horsepower and 380 lb-ft of torque on 2500 models, and is specifically engineered for low-end torque. A version rated at 322 horsepower is standard on 3500s. Pickups with either version are E85 FlexFuel capable.

A bi-fuel version of the 6.0L V-8, with special hardened valves and valve seats to enable operation on gasoline or compressed natural gas, will be available in all three models of the new Silverado HD – regular-cab, crew-cab and double-cab.

Chevrolet will continue to work with a second-stage manufacturer to offer a single-source option for its CNG vehicles. The bi-fuel trucks are built with the specially designed engine, the fuel system is installed by GM’s Tier One supplier, and the completed vehicle is delivered directly to the customer. This process makes ordering the bi-fuel option as seamless as ordering a truck powered by gas or diesel, and ensures the highest level of durability, reliability and safety.

Smart solutions for cargo management

The pickup box is made from roll-formed steel for increased strength and reduced mass, compared with the stamped beds used by major competitors, and it features a range of smart solutions for everyday life.

Silverado’s CornerStep bumper, combined with hand assists built into the new standard box rail protectors, makes it easier to access cargo in the box, especially useful on HD pickups, with their higher ride height. The box is also available with new upper tie-down hooks, under-rail light-emitting diode lighting, and an EZ Lift and Lower tailgate.

An available spray-in bed liner, which bonds to the steel bed to create permanent, water-tight protection for the box, covers the entire bed interior surface below the side rails, including the tailgate and front box top rail.

Enhanced safety and security

The 2015 Silverado HD will be available with segment-exclusive safety features such as Forward Collision Alert, Lane Departure Warning with an Active Safety Seat, and Front and Rear Park Assist. Head-curtain and seat-mounted side airbags are standard on 2500 and available on 3500 models.

Like all Silverados, the 2015 Silverado HD is backed by the best pickup coverage in America, including:

  • 3 year/36,000 mile limited new vehicle warranty;
  • 5 year/100,000 mile limited powertrain warranty;
  • 2 year/24,000 mile schedule maintenance coverage, including diesel exhaust fluid.

Accessories for a wide range of tasks

The 2015 Silverado HD will be available with a broad range of dealer-installed accessories. Exterior accessories include four-inch or six-inch assist steps in chrome or black, 20-inch wheels, body-side moldings, and a range of chrome accents.

All-weather or carpet floor mats help keep the elements at bay, and storage accessories for the console and under the seat help organize tools and information.

Available for the box are retractable side steps, drop-in or spray-in bed liners, bed mats and rugs, and tonneau covers, as well as Trac Rac ladder racks and UWS tool boxes.

Manufacturing

2015 Silverado HD pickups will be assembled in Ft. Wayne, Ind. and Flint, Mich.
