Built for off-road performance, the Chevrolet Colorado ZR2 offers big capability in a mid-sized package. The heavily modified truck sits on a track that's been widened by three and a half inches, with a lifted suspension and new cast-iron control arms for greater durability. It's also the first off-roader to get Chevy's advanced Multimatic Dynamic Suspensions Spool Valve damper technology for improved handling. Rockers have been added to make clearing rocks and obstacles easier, the front and rear bumpers massaged for greater clearance, and the 17-inch rims wrapped in mud-gobbling 31-inch Goodyear Duratrac tires. The standard version is powered by a 3.6L V6 pumping out 308 hp, and a diesel powerplant is available for those looking for more range.
