Although official EPA ratings for the 2016 Chevrolet Colorado and GMC Canyon pickups with the new 2.8-liter Duramax turbodiesel I-4 are pending, independent testing by Emissions Analytics have revealed Real MPG fuel economy numbers in real-world driving. In testing, a four-wheel-drive 2016 Chevrolet Colorado Z71 CrewCab achieved 25.5/29.3/27.1 mpg (9.22/8/8.68 L/100km) city/highway/combined.

Additionally, a two-wheel-drive Chevrolet Colorado LT CrewCab achieved 23.2/31.4/26.3 mpg (10.14/7.49/8.94 L/100km), while a four-wheel-drive GMC Canyon SLT achieved 22.3/29.5/25.0 mpg (10.55/7.97/9.4 L/100km) in testing. Though the trucks may be similar in spec, slight variations between individual models aren’t uncommon.

In comparison, a two-wheel-drive Colorado with the base 2.5-liter gas four-cylinder is EPA-rated 19-20/26-27 mpg (12.4-11.8/9-8.7 L/100km) city/highway depending on transmission (manual/auto), while a four-wheel-drive model with the four-cylinder and automatic is rated 19/25 mpg (12.4/9.4 L/100km). The 3.6-liter gas V-6 is rated 18/26 mpg (13/9 L/100km) with two-wheel drive or 17/24 mpg (13.8/9.8 L/100km) or four-wheel drive.

The base 2.5-liter engine makes 200 hp at 6,300 rpm and 191 lb-ft of torque at 4,400 rpm, while the 3.6-liter engine makes 305 hp at 6,800 rpm and 269 lb-ft at 4,000 rpm. In comparison, the 2.8-liter Duramax makes 181 hp at 3,400 rpm and 369 lb-ft at 2,000 rpm that’s 100 lb-ft more than the available V-6 engine.

Max towing for the 2.5-liter and 3.6-liter without the Z82 trailering package is 3,500 pounds (1,588 kg), while the 3.6-liter with the Z82 trailering package is rated 7,000 pounds (3,175 kg). The 2.8-liter Duramax is tow rated at 7,600-7,700 pounds (3,447-3,493 kg) for four-wheel-drive and two-wheel-drive, respectively.

Currently, the next most fuel-efficient pickup is the Ram 1500 EcoDiesel, which is EPA-rated 20/28 mpg (11.8/8.4 L/100km) city/highway. Emissions Analytics’ testing revealed the Ram EcoDiesel’s EPA rating to be accurate.
