Optimized Fuel Consumption

Lexus GS 450h's power-steering pump and air-conditioning compressor are electrically powered rather than engine-driven to reduce parasitic losses to the engine and thereby improve fuel consumption. This is necessary because the gas engine often shuts down - a fuel-saving benefit of the hybrid system - especially when the vehicle is stopped or driven slowly through traffic. Ultraviolet and infrared ray-reducing tinted glass on all windows helps to reduce demand on the air conditioner.

A regenerative braking system further boosts system efficiency. When the vehicle is coasting or the brakes are applied, the electric motors function as generators, capturing kinetic energy that would normally be lost as heat through the brakes and transforming it into useable electricity to recharge the batteries.


Lexus GS 450h Advanced Safety Systems

All Lexus GS models implement a wide array of advanced safety systems. The Supplemental Restraint System (SRS) includes variable-force front airbags for both the driver and front passenger. Sensors determine the severity of an impact and in turn the airbag deployment force, helping to provide an appropriate level of occupant restraint. The GS features standard seat-mounted side airbags for the front seats, knee airbags for the driver and front passenger, and front and rear side-curtain airbags.

The optional Pre-Collision System (PCS) can help reduce collision damage. A millimeter-wave radar sensor helps detect obstacles in front of the car, while vehicle speed, steering angle and yaw rate inputs help to determine whether a collision is unavoidable. In such a situation, PCS switches the AVS to sport mode for optimal chassis response, preemptively retracts front seat belts, and pre-initializes Brake Assist so that increased braking will be applied the instant the driver depresses the pedal. The active-braking feature will automatically apply the brakes up to a deceleration rate of 0.3 G's if the driver fails to react to system warnings.


New Lexus Design

The next-generation Lexus GS introduced the new Lexus design language that is more sculptural than before - dynamic, free of gimmicks and intriguing in its simplicity. A 112.2-inch wheelbase, long hood, pulled-back cabin and short rear deck create a confident, powerful stance for the GS. A low 0.27 coefficient of drag (Cd) helps to maximize highway fuel efficiency and minimize wind noise.

Subtle visual differences distinguish Lexus GS 450h from other GS models, including a hybrid designation on the side rocker moldings, aluminum-and-blue enameled rear model designation, special 18-inch light-alloy wheels and a power meter that replaces the tachometer. In designing Lexus GS 450h, Lexus raised its own high standards for minimizing noise and vibration. For example, instead of attempting to mask noise, the engineers completely redesigned fans and motors, significantly reducing cabin noise intrusion. New fluid-filled front-engine mounts, additional sound-absorbing asphalt sheets behind the instrument panel, and a new sound-absorbing windshield further enhance the quiet ride that redefines the term "Lexus-like."


Indulgent Yet Intuitive Luxury

Ultra-premium wood, polished-metal accents and leather trim endow the GS interior with a lavish yet high-precision feel. Touch points convey quality, and controls respond fluidly. The three-pod analog instrument cluster features an Electro Chromatic Display (ECD) and variable-transparency glass for high visibility in a variety of light conditions.
