V-6-powered versions of the new 2015 Chevrolet Colorado and GMC Canyon midsize trucks will achieve up to 26 mpg highway according to the EPA. That number is for rear-wheel drive trucks, which are estimated at 18 mpg city and 21 mpg combined; adding four-wheel drive reduces those numbers to 17/24/20 mpg city/highway combined.
One of the big question marks for these new trucks is the possible overlap with GM’s Silverado and Sierra full-size trucks, and in terms of fuel economy the two are closer than you might think. With the 4.3-liter V-6 engine and rear-wheel drive, the Chevrolet Silverado and GMC Sierra achieve 24 mpg highway, a small difference considering those full-size trucks’ greater capabilities. We’ll have to wait on fuel economy numbers for the four-cylinder models before we pass full judgment, though, as the 2.5-liter four that’s standard on both the 2015 Chevrolet Colorado and GMC Canyon may elevate EPA ratings significantly over the much more powerful V-6.
These fuel economy numbers are significantly higher than the 2015 Chevrolet Colorado and GMC Canyon’s closest competitors, the dated Nissan Frontier and Toyota Tacoma pickups. A rear-wheel drive, V-6 Frontier achieves only 16/22/18 mpg, and a Tacoma with this same configuration gets 17/21/19 mpg city/highway/combined. Both of those trucks are relatively old for the automotive market, so it's hardly surprising their fuel-economy numbers lag behind the new trucks, but they are the closest rivals to the Colorado and Canyon.
In addition to the 3.6-liter V-6 and 2.5-liter four-cylinder powertrains for GM’s midsize trucks, the 2015 Chevrolet Colorado and GMC Canyon will also receive a 2.8-liter turbodiesel four-cylinder that should boost mpg numbers even further when it arrives sometime next year. Nissan is also slated to introduce a diesel version of the Frontier soon, though, so the GM trucks won’t be unchallenged for much longer.
