Pontiac's growing GXP lineup has just gained a flagship. The enthusiast division will show a higher-performing G8 at the 2008 New York auto show.
The baddest Holden-turned-Pontiac gets GM's 6.2-liter LS3 small-block V-8, producing 402 hp and 402 lb-ft of torque - 41 hp and 17 lb-ft more than the L76-powered G8 GT. Pontiac predicts a 0-to-60-mph time of 4.7 seconds, with the quarter mile taking 13.0 seconds at 108 mph.
The GXP comes with the six-speed automatic transmission found in the G8 GT but adds a three-pedal option with a Tremec TR6060 six-speed manual. A limited-slip differential is standard, as are Brembo brakes.
Exterior changes are subtle and include revised front and rear fascias. Nineteen-inch polished and machined aluminum wheels are tucked neatly under the G8's flared fenders. Inside, passengers will be greeted by bolstered GXP-embroidered seats.
Pricing hasn't been announced yet, but we expect the GXP to come in right around $35k. For those looking for less power and a similar reduction in weight, Pontiac is also showing a G8 sport truck in New York that will arrive for the 2010 model year.
