The 2008 Lexus GS gets slightly revised styling and a new V8 engine. This is the sportier of Lexus's two premium midsize cars. The GS lineup starts with the GS 350, which has a 303-hp 3.5-liter V6 engine and 6-speed automatic transmission. It's available with rear- or all-wheel drive. New for 2008 is the GS 460. It has a 342-hp 4.6-liter V8 and an 8-speed automatic. GS 460 is rear drive only. Unchanged from 2007 is the gas/electric hybrid GS 450h. The GS 450h teams a gasoline V6 engine with an electric motor to produce 339 hp. Like other Lexus and Toyota hybrids, it can run on one or both of its power sources, depending on driving demands, and requires no plug-in charging. The GS 450h has a continuously variable automatic transmission (CVT). Available safety features include ABS, traction control, antiskid system, curtain side airbags, front side airbags, and front knee airbags. Also standard: leather upholstery and keyless entry and engine start. Many control functions are via a dashboard touch screen that also displays an available navigation system and rearview camera. Other available features include steering-linked headlamps and Lexus' Pre-Collision System, designed to automatically cinch seatbelts and apply brakes if an unavoidable crash is detected.
