Pontiac G8 GXP Spy Shots

Pontiac unveiled the G8 SXP sports sedan earlier this year at the New York Auto Show. The company announced that sales will begin around the end of 2008 as a 2009 model. Here’s now a few spy shots of the pre-production G8 GXP.

The G8 GXP is powered by a 6.2L LS3 small-block V-8, currently rated at 402 hp and 402 lb.-ft. of torque. This engine is the newest member of GM’s small-block V-8 family. It features a revised, larger-bore cylinder block, high-flow, L92-style cylinder heads; larger-diameter pistons; unique camshaft and camshaft timing; revised valvetrain with offset intake rocker arms; high-flow intake manifold; and high-flow fuel injectors.
