Chevrolet introduced the Colorado ZR2 concept for off-road use at the Los Angeles Auto Show that included the new 2.8L Duramax diesel engine that will arrive in the Colorado lineup later next year.

The 2.8L Duramax delivers an estimated 181 hp at 3,400 rpm and 369 lb.-ft. of torque at 2,000 rpm. The four-cylinder engine features a variable-geometry turbocharger for optimal power and efficiency across the rpm band and a balance shaft for greater smoothness. The engine is backed by a six-speed automatic transmission.

The ZR2 concept builds on the capabilities of the production Colorado Z71 off-road package. The Colorado ZR2 is four inches wider than a production Colorado Z71 and including new front and rear fascias designed to increase approach and departure angles when driving off road. Ground clearance and rough terrain are handled with a two-inch lift and integral skid plates, while the wider track helps enhance stability.

The Colorado ZR2’s greater approach and departure angles — 30.7 and 22.7 degrees, respectively, versus the Z71’s 25/21 degrees — are enabled by off-road fascias that drastically reduce front and rear overhang. They also feature integrated, flip-out aluminum tow hooks, and the front fascia incorporates a built-in winch.
