The rear-wheel drive GS series has always been an alternative to those shopping for BMW's 5-series sedan. And like the 5-series with the base engine, the GS350 is likewise available in an all-wheel drive derivative. As it was redesigned for the 2006 model year, there are no major changes for 2008.

Powering the GS350 is an all-aluminum 3.5 liter V6 featuring the Toyota / Lexus take on variable valve timing, called Variable Valve Timing with intelligence (VVT-i) as well as direct injection. It makes 303 horsepower at 6,200 rpm, along with 274 lb-ft at 3,600 rpm. It is exclusively connected to a six-speed automatic transmission. The EPA rates this combination at 19 mpg in the city cycle, and 27 mpg on the highway. The AWD model returns 18 mpg in the city, and 25 on the highway.

The GS comes amply equipped, with only a navigation system and Mark Levinson premium surround sound audio system package and a list of stand-alone options.

Standard fare includes electronic traction and stability control (both with a cut-off switch), dual-stage front airbags, side seat-mounted airbags front and rear, side curtain airbags and knee airbags, four wheel disc brakes with anti-lock control, Brake Assist and electronic brake force distribution. A tire pressure monitoring system is also standard, as are High-Intensity Discharge (HID) headlights, cruise control, dual-zone automatic climate control, 10-way power and heated front seats and Bluetooth support for hands-free calling. The standard sound system is a 10-speaker Lexus Premium Sound System with an in-dash 6-disc changer and auxiliary iPod / MP3 / WMA port.

The more noteworthy options include electronically adjustable suspension damping, a radar-enforced Pre-Collision System and dynamic cruise control, an electronic parking assist and a backup camera, a choice of three 18-inch wheel and tire combinations, and a choice of Sirius or XM satellite radios.
