CAR GARAGE | 2013 Lexus GS 450h | Today, the Lexus GS 450h is the world's first premium performance sedan to be equipped with a V6 Atkinson cycle gas engine and two-motor hybrid system, in a front engine rear-wheel drive vehicle. The hybrid version of the 2013 GS 350 incorporates improvements to its hybrid power train and is equipped with a second-generation Lexus Hybrid Drive system. Lexus GS 450h engineers have aimed for reductions in fuel consumption and emissions, while Providing exhilarating performance. With a total system power output of 338 hp, the Lexus GS 450h will Accelerate effortlessly from 0-60 mph in 5.6 seconds. The new GS hybrid also features a Drive Mode selector.
Rear seat occupants have seat-mounted side airbags, and all four outboard occupants are equipped with side curtain airbags. The system also uses a Lexus first infrared camera to monitor the driver's eyes to check on the driver status.

In Addition to the gas engine and electric motor, the new GS 450h's hybrid drive system is a generator; a high-performance nickel-metal hydride battery; a power split device which, via the planetary reduction gears, combines and re-allocates power from the engine , electric motors and generators According to operational requirements; and a compact power control unit to govern the interaction of the high speed system components. Adapted specifically for the hybrid power train and a first for premium performance sedans, the 3.5-liter V6, DOHC engine benefits from Several technical improvements Including the adoption of the Atkinson Cycle engine design to optimize the fuel-efficient benefits of Lexus Hybrid Drive.
The D-4S system features new slit-type injector nozzles with a modified port shape, a higher pressure for more efficient fuel combustion, and injection port for improved idle characteristics NHV. The cooling performance of the hybrid system's Power Control Unit (PCU) helps Reduced fuel consumption and has been improved through the adoption of dual cooling paths and a single-piece, integrated AC / DC converter. Control system has been enhanced. The motor is driven at lower voltage to Provide a more environmentally-advanced driving performance to help enhance fuel efficiency. The features lighter electric motor mounts and reduced friction.
