BMW X6 vs Chevrolet Traverse: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Chevrolet Traverse burns about $2,650 of fuel annually against $3,150 for the BMW X6. That $500 yearly gap compounds to roughly $2,500 over five years and $4,000 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 versus highway split: the BMW X6 is the stronger commuter at 23 mpg city, while the Chevrolet Traverse pulls ahead on the interstate at 27 mpg highway. If most of your driving is stop-and-go traffic the city figure is the one to weigh; for long-distance highway mileage the reverse is true, and the two vehicles effectively swap places depending on how you drive.

Powertrain choice: the BMW X6 is recorded with 4 distinct engine configurations (SIDI; Mild Hybrid, SIDI & PFI; Mild Hybrid, SIDI), the Chevrolet Traverse with 1 (SIDI). Across 47 recorded BMW X6 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 X6 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 Standard 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 X6 emits 359 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.
