Chevrolet made good on its promise to offer a diesel in the mid-sized Colorado pickup truck, including the option for a 2.8L Duramax turbodiesel in the 2016 LT and Z71 Crew Cab models with 2WD or 4WD.
Rated 181 hp and 369 lb.-ft. of torque, the all-new 2.8L Duramax lifts Colorado’s maximum trailering capacity to 7,700 lb. on 2WD models and 7,200 lb. in 4x4s, handily out-towing full-size Chevy Silverados powered by the 4.3L EcoTec3 V6.
“A diesel engine was part of the Colorado’s portfolio plan from the very beginning,” said Scott Yackley, assistant chief engineer, “Meaning the chassis, suspension and other elements of its architecture were engineered to support its capability.”
Colorado’s new 2.8L Duramax is part of General Motors’ global family of turbo-diesel four-cylinder engines. It’s built on an iron block and aluminum DOHC cylinder head. The compression ratio is 16.5:1, and employs a common rail direct injection fuel system.
GM says it the 2.8L Duramax is the cleanest diesel truck engine the company produces. It meets U.S. emissions standards, thanks in part to cooled exhaust-gas recirculation (EGR).
A broad torque band makes it very powerful at low rpm, while a variable-geometry turbocharger helps deliver smooth horsepower on demand.
EPA fuel-economy numbers are not yet available, but Chevy projects estimated fuel economy to top Colorado’s segment-leading 27 mpg with the 2.5L gasoline engine and automatic transmission. Australian Colorado owners report fuel economy with the global 2.8L Duramax in the 28 mpg range.
The new Colorado diesel goes on sales this fall, priced $3,730 more than a comparably equipped 3.6L V6 model.
