Jaguar E-Pace vs Subaru Ascent: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Subaru Ascent burns about $2,650 of fuel annually against $3,150 for the Jaguar E-Pace. 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 Subaru Ascent is the stronger commuter at 21 mpg city, while the Jaguar E-Pace pulls ahead on the interstate at 28 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 Jaguar E-Pace is recorded with 2 distinct engine configurations (SIDI, SIDI; Mild Hybrid), the Subaru Ascent with 1 (SIDI). Across 12 recorded Jaguar E-Pace 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 Jaguar E-Pace is offered with 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 Jaguar E-Pace emits 371 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.
