Ford Explorer vs GMC Acadia: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Ford Explorer burns about $2,200 of fuel annually against $2,450 for the GMC Acadia. That $250 yearly gap compounds to roughly $1,250 over five years and $2,000 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 Ford Explorer is the stronger commuter at 27 mpg city, while the GMC Acadia pulls ahead on the interstate at 29 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 Ford Explorer is recorded with 4 distinct engine configurations (SIDI, SIDI & PFI, SIDI & PFI; FFV), the GMC Acadia with 1 (SIDI). Across 102 recorded Ford Explorer 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 Ford Explorer is offered with Part-time 4-Wheel Drive, Rear-Wheel Drive, Front-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 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 Ford Explorer emits 322 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.
