EPA fuel economy ratings are finally out for the 2016 Chevrolet Colorado diesel, totaling 22 mpg in the city and 31 mpg on the highway for rear-wheel-drive versions. Four-wheel-drive diesel models earn ratings of 20 mpg in the city and 29 highway.
These impressive ratings make the 2016 Chevrolet Colorado Diesel and its GMC Canyon twin the most fuel-efficient pickups in America. For comparison, the standard four-cylinder gas-powered, rear-wheel-drive 2016 Chevrolet Colorado is rated for 20 mpg in the city and 27 mpg highway, versus 19 mpg city and 25 mpg highway for four-wheel-drive models.
Ram is the other major player in the diesel truck world, at least until the Nissan Titan XD goes on sale. Although the diesel-powered Ram 1500 is larger than the mid-size Colorado, it still manages 20 mpg city and 28 mpg highway with rear-wheel-drive, and HFE (high fuel economy) models up that performance to 21 mpg city and 29 mpg highway.
Part of the reason for the delay in releasing EPA ratings was that the government organization (along with CARB) was taking a closer look at diesel engines in the wake of the VW emissions scandal. Additional testing, both in the lab and on the road, revealed nothing out of compliance with emissions in these GM trucks.
Now emissions certified, the 2.8-liter Duramax turbodiesel engine in the 2016 Chevrolet Colorado Diesel makes 181 hp and 369 lb-ft of torque. With so much muscle on tap, rear-wheel-drive models can tow 7,700 pounds with the optional trailering package (7,600 with four-wheel-drive).
The 2016 Chevrolet Colorado Diesel should be going on sale any day now, available on LT and Z71 Crew Cab models. The starting price is $33,420 including destination for a short-box, rear-wheel-drive version.
