Power comes from a slightly detuned version of the LS3 6.2L V8 engine found in the Corvette. Producing 402hp and 402 ft-lbs of torque in the GXP, the car has a healthy increase of 41 hp and 16 ft-lbs of toque over the GT versions.

A few weeks ago we brought you news that GM was preparing to introduce a GXP variant for the Pontiac G8 sedan.  Now the company has officially released information regarding the model ahead of its New York Auto Show debut.

Power comes from a slightly detuned version of the LS3 6.2L V8 engine found in the Corvette. Producing 402hp and 402 ft-lbs of torque in the GXP, the car has a healthy increase of 41 hp and 16 ft-lbs of toque over the GT version. GM estimates a 0-60 mph time of 4.7 seconds and a quarter mile time of 13 seconds flat at 108 mph.

Making an appearance on the G8 options list for the first time is a six speed manual transmission. Both automatic and manual versions will come with a limited-slip differential. A Nürburgring tuned sport suspension and powerful Brembo brakes ensure the GXP has more sporting potential than anything Pontiac has made in decades.

Exterior differences include new polished aluminum 19-inch wheels, a unique front fascia and a distinctive rear diffuser. The interior comes standard with two-tone sport seats with color-coordinated gauge cluster and GXP embroidery, a leather-trimmed steering wheel and gear shifter, and alloy sport pedals.
