The Pontiac G8 is the first North American application of GM’s new global rear-wheel-drive architecture. The 2009 lineup comprises three models: G8, G8 GT and the new G8 GXP.

The base G8 receives a 3.6L V-6 rated at 256 horsepower. The G8 GT is powered by a uniquely configured 6.0L small-block V-8, rated at 361 horsepower and features Active Fuel Management technology, which allows the engine to switch from V-8 power to four-cylinder. The GXP packs a 6.2L V-8 that tops 400 horsepower.

The GXP takes the G8’s responsive driving, refined passenger environment and aggressive good looks to a new level, with distinctive design cues, unique interior elements and a stirring driving experience. It rewards the driver with sharp, immediate responses, and a well-balanced road feel during spirited driving.

A Brembo braking system matches the GXP’s boost in performance with an equivalent increase in stopping power. The system includes 14-inch vented front and 12.76-inch rear disc rotors, with special quad-piston alloy calipers in front.

The GXP rides on unique 19-inch polished aluminum wheels with a special machined face. Performance summer tires are standard and a comparable all-season tire is available.

Base model estimated mpg: 17/25

Estimated starting price: $27,995
