Chevrolet Colorado vs GMC Canyon: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Chevrolet Colorado burns about $2,800 of fuel annually against $2,800 for the GMC Canyon. That $0 yearly gap compounds to roughly $0 over five years and $0 over eight — often more than the price difference between two trims of the same vehicle, and the single largest running-cost line item separating these two.

City and highway economy: the GMC Canyon leads in both cycles — 22 mpg city and 30 mpg highway against 22 and 30 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Chevrolet Colorado is recorded with 4 distinct engine configurations (SIDI, SIDI; Late Model Year, SIDI; Stop-Start), the GMC Canyon with 2 (SIDI, 2.8). Across 91 recorded Chevrolet Colorado configurations and 74 for the GMC Canyon, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the Chevrolet Colorado is offered with 4-Wheel Drive, Rear-Wheel Drive, the GMC Canyon with 4-Wheel Drive, Rear-Wheel Drive. All-wheel drive typically costs one to two mpg combined against the same vehicle in front- or rear-wheel drive, which is worth remembering when the gap between these two is small. The EPA classes them as Small Pickup Trucks 4WD and Small Pickup Trucks 2WD respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the Chevrolet Colorado emits 396 g/mile of CO2 versus 396 g/mile for the GMC Canyon. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
