BMW X2 vs Mercedes-Benz CLE-Class: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the BMW X2 burns about $2,700 of fuel annually against $2,700 for the Mercedes-Benz CLE-Class. That $0 yearly gap compounds to roughly $0 over five years and $0 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 Mercedes-Benz CLE-Class leads in both cycles — 24 mpg city and 34 mpg highway against 24 and 34 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the BMW X2 is recorded with 2 distinct engine configurations (SIDI & PFI, SIDI), the Mercedes-Benz CLE-Class with 1 (SIDI; Mild Hybrid). Across 23 recorded BMW X2 configurations and 23 for the Mercedes-Benz CLE-Class, 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 X2 is offered with All-Wheel Drive, Front-Wheel Drive, the Mercedes-Benz CLE-Class 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 Midsize Cars and Subcompact Cars 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 X2 emits 314 g/mile of CO2 versus 323 g/mile for the Mercedes-Benz CLE-Class. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
