BMW X3 vs Ford Explorer: what the numbers mean
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 $2,600 for the BMW X3. 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 versus highway split: the Ford Explorer is the stronger commuter at 27 mpg city, while the BMW X3 pulls ahead on the interstate at 33 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 X3 is recorded with 4 distinct engine configurations (SIDI & PFI; Mild Hybrid, SIDI, SIDI; Mild Hybrid), the Ford Explorer with 4 (SIDI, SIDI & PFI, SIDI & PFI; FFV). Across 47 recorded BMW X3 configurations and 102 for the Ford Explorer, 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 Ford Explorer with Part-time 4-Wheel Drive, Rear-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 4WD 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 322 g/mile for the Ford Explorer. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
