Colin McRae Rally and DiRT Wiki

The Bison is a factory-modified version of the Chevrolet Colorado ZR2. Like the standard model, it is available with both the 3.6-litre V6 petrol, and 2.8-litre 4-cylinder turbodiesel, engines.

The Bison is upgraded with components developed by aftermarket company American Expedition Vehicles, which are installed on the General Motors assembly line. While it does not have any more power or suspension travel, its track is 3.5-inches wider, and it rides 2 inches higher than standard. It is fitted with stamped-steel front and rear bumpers, boron-steel skid plates, and larger fender flares.[1]
