Motor Trend logo Motor Trend 7/28/2015 Jason Udy

GM has revealed more details about the upcoming Duramax turbodiesel in the 2016 Chevrolet Colorado and GMC Canyon pickups. With the 2.8-liter Duramax diesel, rated 181 hp and 369 lb-ft of torque, the two-wheel-drive models can tow up to 7,700 pounds while four-wheel-drive models can tow up to 7,600 pounds.

The 2016 Colorado and Canyon have a Gross Vehicle Weight Rating of 6,600 pounds for two-wheel-drive models and 6,200 pounds with four-wheel drive. GM credits the midsize pickup’s fully boxed frame for the towing and payload capabilities.

Other features include a smart diesel exhaust brake system as well as an all-new, standard trailering package, which includes an integrated trailer brake controller, hitch receiver, seven-pin connector, and an automatic locking rear differential with a 3.42 rear axle ratio, and four-wheel disc brakes. Additionally, four-wheel-drive models feature a new electronically controlled two-speed transfer case.

Available on Colorado LT and Z71 and Canyon SLE and SLT Crew Cab models, with two-wheel or four-wheel drive, the Duramax diesel is priced $3,730 more than a comparably equipped Colorado or Canyon with the 3.6-liter V-6 engine. That engine is rated 305 hp and 369 lb-ft of torque. GM says the Duramax diesel’s variable geometry turbocharger gives it a wide power curve with peak torque available at 2,000 rpm and peak horsepower at 3,400 rpm.

The 2.8-liter Duramax features an iron cylinder block with a forged steel crankshaft and connecting rods, and a 16.5:1 compression ratio. Its aluminum DOHC heads feature common rail direct injection, while a balance shaft should reduce harshness. The engine is also B20 bio-diesel compatible. GM claims the 2.8-liter Duramax engine is its cleanest diesel truck engine. Although official EPA-rated fuel economy ratings are yet to be released, GM expects the Duramax to return better fuel economy than either of the available gas engines including the base 2.5-liter inline-four EPA-rated at 19-20/25-27/21-22 mpg city/highway/combined.
