BMW X4 vs Ford Edge: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Ford Edge burns about $2,450 of fuel annually against $3,050 for the BMW X4. That $600 yearly gap compounds to roughly $3,000 over five years and $4,800 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 X4 is the stronger commuter at 23 mpg city, while the Ford Edge pulls ahead on the interstate at 30 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 X4 is recorded with 2 distinct engine configurations (SIDI, SIDI; Mild Hybrid), the Ford Edge with 4 (SIDI, SIDI; with Semi-Auto Trans, 3.5). Across 35 recorded BMW X4 configurations and 45 for the Ford Edge, 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 X4 is offered with All-Wheel Drive, the Ford Edge 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 Small 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 X4 emits 351 g/mile of CO2 versus 360 g/mile for the Ford Edge. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
