2.8L Duramax LWN Diesel

4 Cyl Duramax Powered Colorado, Canyon Midsize Pickups

GM’s midsize pickup trucks, the Chevrolet Colorado and GMC Canyon, debuted with a class exclusive diesel engine platform for the 2016 model year. The optional 2.8L Duramax turbodiesel produces 181 horsepower and 369 lb-ft of torque in addition to carrying a maximum 7,700 lbs. tow rating (properly equipped). The mini-Duramax diesel also displays best-in-class fuel economy in the Colorado and Canyon, earning up to an EPA rated 22 mpg in the city and 31 mpg on the highway. The impressive new Colorado and Canyon models thereby claim Best-in-class torque, fuel economy, and towing for the 2016 model year.

Note - this article pertains to diesel equipped GMC Canyon and Chevrolet Colorado models. All specifications for gas engine equipped Canyon/Colorado models has been omitted.

The VGT equipped Duramax comes standard with a “smart diesel exhaust brake system”, integrated electronic trailer brake controller, and 3.42:1 automatic rear locking differential. Power is managed by GM’s 6L50 Hydra-Matic six speed automatic transmission. The diesel equipped Colorado and Canyon models help bridge the gap between the midsize and fullsize pickup segments as a result of its capabilities. Two wheel drive models are rated with a maximum GVWR of 6,000 lbs and a maximum trailer tow capacity of 7,700 lbs, while four wheel drive pickups will feature a 6,200 lbs GVWR and slightly lower 7,600 lbs maximum trailer weight.

The GMC Canyon and Chevrolet Colorado have managed to earn a variety of awards and accolades, in addition to claiming several "Best-in-class" titles following the Duramax's debut. GM's closest competitor with respect to fuel efficiency is FCA's EcoDiesel equipped Ram 1500 (21 city/29 highway mpg, respectively), although the Ram technically competes in the fullsize pickup segment. In the midsize market, Toyota's Tacoma continues to reign supreme with regard to sales volume. However, the widely popular Tacoma falls short to the Colorado and Canyon for 2016 in several categories. Only time will tell whether or not the midsize Duramax platform from General Motors will be enough to encroach on Toyota's significant market share in the sector.
