Toyota unveiled the 2007 Lexus GS 450h last month at the New York Auto Show. Toyota says the GS 450h is the world’s first hybrid luxury sedan and the first full hybrid vehicle with a front engine and rear wheel drive. A new Lexus Hybrid powertrain was created to power the new 450h, according to Toyota. The system combines a 3.5-liter V-6 engine with a high-output, permanent magnet electric motor—all driving the rear wheels. Combined power output is estimated to be in excess of 300 horsepower, with zero-to-60 acceleration in less than six seconds. Toyota says the engine’s torque capabilities put it at an acceleration performance level similar to a V-8 engine. Combined fuel economy is estimated to be in the high twenties, a level more typical of a 2.0-liter four-cylinder compact sedan. The car’s EPA emissions ratings will be one of the best in the industry, Toyota says. Based closely on the new GS luxury sport sedans, the GS 450h is designed to be the premium model in the GS series. Many of the optional features from the GS 300 and 430 will be standard on the GS 450h. The Lexus GS 450h is targeted for sale beginning in the spring of 2006.
