Forza Motorsport 4 - 2009 Jeep Grand Cherokee SRT8

Heavyweight contender

Debuted at the 2005 New York International Auto Show as a 2006 model, the SRT8 version of the Jeep Grand Cherokee transformed the SUV into a sport utility muscle car, combining the thrills of a muscle sports car and the versatility of a sport utility vehicle into one clever package.

It was powered by a 6.1L HEMI V8 engine that generates about 420 hp (310 kW) of power. It comes with upgraded Brembo brakes, a special transfer case, an electronic all-wheel-drive system and interior and exterior updates. It is the fastest naturally-aspirated production SUV when it was launched.
