BMW X3 vs Chevrolet Traverse: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the BMW X3 burns about $2,600 of fuel annually against $2,650 for the Chevrolet Traverse. That $50 yearly gap compounds to roughly $250 over five years and $400 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 BMW X3 leads in both cycles — 27 mpg city and 33 mpg highway against 20 and 27 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the BMW X3 is recorded with 4 distinct engine configurations (SIDI & PFI; Mild Hybrid, SIDI, SIDI; Mild Hybrid), the Chevrolet Traverse with 1 (SIDI). Across 47 recorded BMW X3 configurations and 30 for the Chevrolet Traverse, 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 BMW X3 is offered with All-Wheel Drive, Rear-Wheel Drive, the Chevrolet Traverse 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 BMW X3 emits 204 g/mile of CO2 versus 387 g/mile for the Chevrolet Traverse. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
