Chevrolet showcases coming new 2.8L Duramax diesel in Colorado ZR2 Concept

At the Los Angele Auto Show, Chevrolet introduced the Colorado ZR2 concept as a vision of how Chevrolet could take the all-new midsize truck’s off-road capability to the next level. It also showcased the new 2.8L Duramax diesel engine that will arrive in the Colorado lineup later next year.

The Colorado ZR2 concept’s new 2.8L Duramax diesel offers an estimated 181 hp (135 kW) at 3,400 rpm and 369 lb-ft (500 N·m) of torque at 2,000 rpm.

The 2.8L Duramax diesel is part of a new, global family of turbo-diesel four-cylinder engines designed to deliver more-efficient capability. It 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.
