The Pontiac G8 GT and G6 GXP both made appearances in 50's "Amusement Park" video, and more recently 50 unveiled his own custom G8 at the SEMA Auto Show.
The engine assembly was filled out with a variety of production-based components used on the Corvette Z06's 7.0L LS7 engine, including a forged steel crankshaft, lightweight titanium connecting rods, racing-derived aluminum cylinder heads and a complete LS7 intake/throttle body/fuel injection system.
For the interior, standard leather seats were re-trimmed with perforated red leather inserts and matching trim was used for the door inserts and armrests. The car was also outfitted with an 800-watt JBL audio system with amps and a subwoofer.
50's not the only one helping GM market their cars; the company had extensive product placements in the Transformers film, and the Chevrolet Camaro Concept recently appeared in a T.I. video.
