Chevrolet Trax vs GMC Acadia: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Chevrolet Trax burns about $2,050 of fuel annually against $2,450 for the GMC Acadia. That $400 yearly gap compounds to roughly $2,000 over five years and $3,200 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 Chevrolet Trax leads in both cycles — 28 mpg city and 34 mpg highway against 22 and 29 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Chevrolet Trax is recorded with 3 distinct engine configurations (SIDI, SIDI; FFV, 1.4), the GMC Acadia with 1 (SIDI). Across 23 recorded Chevrolet Trax configurations and 44 for the GMC Acadia, 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 Trax is offered with Front-Wheel Drive, All-Wheel Drive, the GMC Acadia with All-Wheel Drive, Front-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 Sport Utility Vehicle 4WD and Standard Sport Utility Vehicle 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 Trax emits 296 g/mile of CO2 versus 349 g/mile for the GMC Acadia. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
