Powertrain Options and Availability
In the 2006 model year, the GS 300 had a 245-horsepower V6 engine, while the GS 430 held a 300-horsepower V8. A larger (3.5-liter) engine went into the V6 model for 2007, and the GS 430 was re-rated at 290 hp. All models used a six-speed automatic transmission with manual shift gate, except for the GS 450h hybrid. That sedan used a combination of 3.5-liter V6 gasoline engine and an electric motor, with a continuously variable transmission (CVT). Only the V6 sedan could be equipped with all-wheel drive. For 2008, a 342-horsepower 4.6-liter V8 and an 8-speed automatic joined the engine lineup.
