Lexus added a hybrid version to its GS lineup for the first time in 2006 when the model was in its third generation. Once the fourth-generation GS was announced for the 2013 model year, the GS 450h was also updated with a more aggressive exterior look, a more powerful engine and improved fuel economy.

For the 2014 model year, the GS 450h will evolve even further, thanks to some new features. Lexus will add new standard features like Siri Eyes Free technology licensed from Apple and Climate Concierge.

Lexus also updated The Luxury Package with new features, like LED fog lights, a Liquid Graphite finish for the 18-inch wheels and the discontinuing of the Lexus Night View system. A series of new optional features will also be added to the model.

Under the hood, the GS 450h keeps the usual Lexus Hybrid Synergy Drive system that helps it deliver some of the best fuel economy in its class.

As expected, the 2014 GS 450h will feature the same design language as its gasoline-only sibling, with exception of some additional features that will help us recognize it as a hybrid model.

Up front, the GS 450h gets a three-lamp design that combines high and low beam LED lights and turn signals in a single horizontal row, while the taillights feature an L-shape design and come with LED technology. The model will get discreet, blue hybrid badges on the side skirts and a special "GS 450h" badge on the rear.

The only real addition on the outside is the optional trunk opener.

2014 Lexus GS 450h High Resolution Drivetrain
- image 525765

No changes were made under the hood, so the 2014 GS 450h continues to offer the usual Lexus Hybrid Synergy Drive system. It combines an Atkinson cycle 3.5-liter, V-6 engine that produces 286 horsepower at 6,000 rpm and 254 pound-feet of torque at 4,600 rpm with two water-cooled, permanent-magnet electric motors. The first electric motor produces 180 horsepower, and acts as the primary generator, starts the engine and controls speed. The second motor produces 200 horsepower, and drives the rear wheels and works to develop additional power through the 450h’s regenerative-braking system.

In total, the system delivers a total of 338 horsepower and it all travels through a revised CVT transmission that now features eight steps. This allows the 450h to sprint from 0 to 60 mph in just 5.6 seconds and up to a top speed of 131 mph.

On top of this rather stout performance, the 450h also turns in an impressive 29 mpg city, 34 mpg highway and 31 mpg combined.

The 2014 GS450h comes with the Lexus Drive Mode selector that features five modes: two focused on economy and three on sports driving. The ECO mode sets the climate-control system and other unnecessary luxuries to reduce battery consumption and save energy. The EV mode is for short distances only, and it allows the 450h to travel on electric power only. The Sport, Sport S and Sport S+ modes help improve throttle response and transmission control for a sharper driving experience.

Sport S+ allows the 450h to use all of its power and handling programs, like Adaptive Variable Suspension, electric power steering system and Vehicle Dynamic Integrated Management (VDIM), to deliver ideal performance.

While not as cool as its Asian competitors, the ActiveHybrid 5 can be an alternative for those real German cars addicts. The model combines a in-line six-cylinder engine with BMW TwinPower Turbo technology, an electric-drive system and an eight-speed automatic gearbox for a total output of 340 horsepower. This allows it to sprint from 0 to 60 mph in 5.9 seconds and deliver a fuel economy of 44 to 40 mpg.

If we were buying a hybrid sedan, then the GS 450h would be out first choice. First of all, it looks really sharp, which is mostly suitable for a sports sedan rather than a hybrid one. Secondly, the powerful drivetrain, high fuel economy numbers and impressive list of the updates just make a good thing better.

    • Can be pretty expensive
    • Not the greatest mpg for a hybrid

Press Release

The 2014 Lexus GS 450h presents a striking dichotomy in performance and efficiency. Its Lexus Hybrid Synergy Drive system delivers 338 total system horsepower for dazzling performance, yet this dramatically styled, spacious sedan also delivers EPA fuel economy ratings on par with cars half its power: 29 mpg city, 34 mpg highway and 31 mpg combined.

The fuel economy of the new-generation GS 450h represents an impressive 35 percent improvement over the previous generation GS hybrid model, a testament to the brand’s relentless pursuit of luxury hybrid leadership. Lexus was the first luxury brand to introduce a hybrid model nearly 10 years ago and today offers five hybrids, the most of any luxury car brand.

Driving a GS 450h, the driver will be struck by the uncanny smoothness of the powertrain. The Lexus Hybrid Drive system teams the output of an Atkinson cycle 3.5-liter V6 engine with a water-cooled permanent magnet electric motor through a planetary-type continuously variable transmission. Independently or in parallel as needed, the gas engine and electric motor drive the rear wheels. The high performance nickel-metal hydride battery pack uses a stacked design to improve trunk space, which is greater than even the gas-only models of the previous generation GS.

Thanks to high system torque at all speeds, and a zero-to-60 mph acceleration in just 5.6 seconds, the GS 450h will feel more like a V8 to the driver. But it uses fuel like a four-cylinder engine. That’s just one element in its performance-oriented persona. Drivers looking for more control and engagement from a hybrid model will find it in the GS 450h, which comes equipped with Lexus Drive Mode selector featuring five modes.

Normal mode offers a balance of efficiency and performance response that’s ideal for everyday driving and yields the smoothest driving experience. Two of the modes focus on fuel economy. ECO mode sets throttle mapping, seat heating and climate control systems to prioritize energy conservation. When driving in ECO mode, instrument meter lighting changes to blue. The EV mode allows the vehicle to be driven short distances, under certain circumstances, using only the electric motor.

Driving enthusiasts will welcome the SPORT S and SPORT S+ modes. SPORT mode transforms the car’s personality, with sharper throttle response and transmission control that mimics the stepped shifting of an eight-speed automatic transmission (compared to six steps in the 2013 model). Instrument meter lighting changes, appropriately, to red when driving in SPORT S mode.

Selecting SPORT S+ mode also engages a sport setting for the Adaptive Variable Suspension, electric power steering system and Vehicle Dynamic Integrated Management (VDIM). In this mode, the GS 450h drives like no other hybrid sedan, adding a sporting edge to the handling while maintaining the classic Lexus smoothness and comfort.

Long a leader in user technology that’s easy to use, Lexus has standard integrated Siri® Eyes Free Mode, with technology licensed from Apple®, in the 2014 GS 450h. Compatible with the iPhone® 4S and iPhone 5 models forward, Siri lets you call contacts, select and play music from iTunes®, get turn-by-turn navigation through Siri and Apple maps, and much more. To help keep eyes on the road and hands on the wheel, Siri can read notifications, read calendar information and allow you to add reminders, calendar appointments and notes.

Subtle but Distinctive Look for Hybrid Model

2014 Lexus GS 450h High Resolution Exterior

Sharing the dramatic new design of the GS 350 gas model, the GS 450h conveys its hybrid identity with elegant subtlety. In front, an available three-lamp design combines high and low beam LED lamps and turn signals in a single horizontal row. At the rear, the GS 450h shares the gas model’s L-shaped LED tail lamps and stabilizing fins in the bumper’s lower section and also conceals the tailpipes. Discrete blue hybrid badging completes this high-tech, high-efficiency model’s distinguishing features.

Even with its sweeping, coupe-like profile, the Lexus GS 450h provides ample headroom for rear-seat passengers. The new-generation GS offers greater rear headroom, knee room, legroom and foot space than in the previous GS, yet in a sleeker package.

The Art of Lexus Luxury
The cabin of the Lexus GS 450h is nothing short of sumptuous. The standard 10-way power front seats, and the rear seats, are trimmed in soft perforated leather. The GS 450h features matte bamboo trim and comes with additional standard luxury features over the GS 350, includingheated and ventilated front seats, a heated steering wheel, power rear sunshade and a high-intensity interior heater.Rear seat passengers are treated no less regally, with deeply scalloped seats providing excellent support and generous legroom for long trips.

Lexus puts more personal control in climate control with the GS 450h. A first-in-class technology, the energy-saving S-Flow automatic climate control system detects if there is a front passenger and directs airflow only to the occupied front seat or seats.

New for 2014, the Climate Concierge feature, similar to that in the Lexus LS flagship sedan, personalizes climate control for passengers. In the GS 450h, the system automatically monitors the temperature of three separate climate zones and adjusts not only the fans, but also the temperature of the seats and steering wheel according to preset preferences. Each zone will achieve its pre-set level of comfort as quickly as possible.

Advanced Connectivity, Easy Controls Through Touch and Voice
In the Lexus GS 450h, user technology works for the user, not the other way around. The next-generation Remote Touch with one-push confirmation is standard and enables smooth, intuitive control of climate, audio, phone, the optional navigation system and more. A standard rear back-up camera adds security and convenience.

Located front and center, and central to that technology, a vibrant high-resolution control display provides easy access to a multitude of vehicle features. Equipping the GS 450h with the optional navigation system adds a stunning 12.3-inch multimedia display with split-screen capability. The driver and passenger can view a large map display on the left while also monitoring audio, climate or other vehicle information on the right.
