Lexus GS 450h 2013 was unveiled at the Frankfurt Auto Show 2011. Back in 2007, the GS 450h was the first hybrid-powered luxury sport sedan to enter the market and today, the 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.
With a total system power output of 338 hp, the GS 450h accelerates effortlessly from 0-60 mph in 5.6 seconds. As with all Lexus hybrid vehicles, the new GS 450h is a full hybrid capable of operating in gas-only or electric-only modes, as well as a combination of both. Its Lexus Hybrid Drive system features an ultra-smooth running, Atkinson cycle 3.5-liter V6 engine mated to a compact, high-output, water-cooled permanent magnet electric motor. The two powerplants drive the rear wheels both independently and in tandem, as needed.
In addition to the gas engine and electric motor, the new GS 450h’s hybrid drive system a generator a high-performance nickel-metal hydride battery a power split device which, via planetary reduction gears, combines and re-allocates power from the engine, electric motor and generator according to operational requirements and a compact power control unit to govern the high speed interaction of the system components.
Adapted specifically for the hybrid powertrain 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 electric motor features lighter mounts and reduced friction. The system’s regenerative braking operation range has been expanded, contributing to further improvements in fuel efficiency. In addition, the battery layout has been redesigned. A new stacked configuration maximizing luggage space allows the 2013 GS 450h to have more cargo area than the previous generation gas model
