We’ve already seen the new Pontiac G8 star in concept form in one of 50 Cent’s rap videos and now we have news of Fiddy’s own G8, which was unveiled this week at the SEMA Auto Show by the rapper himself. To build the car 50 Cent teamed up with New York-based tuner Unique Autosports and in the process created a one-of-a-kind G8 performance sedan.

The new car is totally customized, with custom paint and exterior appointments, as well as a revised interior and powertrain. The car is powered by an LSX 427 engine dyno-tested to more than 500hp and assembled only with components available from the GM Performance Parts.

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.

Inside, the standard leather seats were re-trimmed with perforated red leather inserts and matching trim was used for the door inserts and armrests. The finishing touch for the G8 is an 800-watt JBL audio system, with complementing amps and a subwoofer.
