Ford Bronco Sport vs Subaru Ascent: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Ford Bronco Sport burns about $2,300 of fuel annually against $2,650 for the Subaru Ascent. That $350 yearly gap compounds to roughly $1,750 over five years and $2,800 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 and highway economy: the Ford Bronco Sport leads in both cycles — 25 mpg city and 30 mpg highway against 21 and 27 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Ford Bronco Sport is recorded with 2 distinct engine configurations (SIDI & PFI, SIDI), the Subaru Ascent with 1 (SIDI). Across 14 recorded Ford Bronco Sport configurations and 18 for the Subaru Ascent, 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 Bronco Sport is offered with 4-Wheel Drive, Part-time 4-Wheel Drive, All-Wheel Drive, the Subaru Ascent with All-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 Ford Bronco Sport emits 324 g/mile of CO2 versus 384 g/mile for the Subaru Ascent. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
