Official EPA-rated fuel economy numbers for the 2016 Chevrolet Colorado and 2016 GMC Canyon with the 2.8-liter Duramax turbodiesel I-4 have been announced.

Two-wheel-drive versions of the midsize pickups are EPA-rated 22/31/25 mpg (10.7/7.6/9.4 L/100km) city/highway/combined, while four-wheel-drive models are EPA-rated 20/29/23 mpg (11.8/8.1/10.2 L/100km). The rating makes the Colorado and Canyon Duramax pickups the most fuel-efficient pickups currently available in the U.S. With its 21-gallon fuel tank, a two-wheel-drive model has a claimed estimated maximum highway range of 651 miles on one tank of fuel.

In our Real MPG testing, both two-wheel-drive and four-wheel-drive versions of the 2016 Chevrolet Colorado with the Duramax turbodiesel achieved higher fuel economy numbers than the official EPA ratings. A two-wheel-drive 2016 Colorado LT achieved 23.2/31.4/26.3 mpg (10.1/7.5/8.9 L/100km), while a four-wheel-drive 2016 Colorado Z71 achieved 25.5/29.3/27.1 mpg (9.2/8/8.7 L/100km).

Those represent differences of 1.2/0.4/1.3 mpg (196/588/181 L/100km) for the two-wheel-drive model and 5.5/0.3/4.1 mpg (42.7/784/57.4 L/100km) for the four-wheel-drive pickup.

Additionally, the EPA has issued a Certificate of Conformity for the turbodiesel pickups saying there were no issues or concerns regarding the emission control system in the vehicle.

The 2.8-liter Duramax turbodiesel is rated 181 hp and 369 lb-ft of torque. A GM Hydra-Matic 6L50 six-speed automatic transmission backs the engine. With the available trailering package, two-wheel-drive pickups can two up to 7,700 pounds (3,493 kg), while four-wheel-drive pickups can tow up to 7,600 pounds (3,447 kg).

The fuel-efficient turbodiesel engine is available on 2016 Chevrolet Colorado LT and Z71 Crew Cab models and 2016 GMC Canyon SLE and SLT Crew Cab models. Pricing for the Duramax engine is $3,700 USD more than a comparably equipped V-6 model. The engine upgrade will be available this fall.
