Mercedes-Benz GLE-Class vs Subaru Crosstrek: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Subaru Crosstrek burns about $1,700 of fuel annually against $3,150 for the Mercedes-Benz GLE-Class. That $1,450 yearly gap compounds to roughly $7,250 over five years and $11,600 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 Subaru Crosstrek leads in both cycles — 36 mpg city and 36 mpg highway against 23 and 29 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Mercedes-Benz GLE-Class is recorded with 4 distinct engine configurations (SIDI; Mild Hybrid, SIDI; PHEV, SIDI), the Subaru Crosstrek with 4 (SIDI; Hybrid, SIDI, SIDI; PHEV). Across 92 recorded Mercedes-Benz GLE-Class configurations and 36 for the Subaru Crosstrek, 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 Mercedes-Benz GLE-Class is offered with All-Wheel Drive, Rear-Wheel Drive, 4-Wheel Drive, the Subaru Crosstrek 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 Standard 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 Mercedes-Benz GLE-Class emits 99 g/mile of CO2 versus 151 g/mile for the Subaru Crosstrek. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
