Acura MDX vs Mercedes-Benz GLE-Class: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Acura MDX burns about $2,800 of fuel annually against $3,150 for the Mercedes-Benz GLE-Class. 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 versus highway split: the Acura MDX is the stronger commuter at 26 mpg city, while the Mercedes-Benz GLE-Class pulls ahead on the interstate at 29 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 Acura MDX is recorded with 4 distinct engine configurations (SIDI, Hybrid, 3.0), the Mercedes-Benz GLE-Class with 4 (SIDI; Mild Hybrid, SIDI; PHEV, SIDI). Across 39 recorded Acura MDX configurations and 92 for the Mercedes-Benz GLE-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 Acura MDX is offered with All-Wheel Drive, Front-Wheel Drive, the Mercedes-Benz GLE-Class with All-Wheel Drive, Rear-Wheel Drive, 4-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 Mercedes-Benz GLE-Class emits 99 g/mile of CO2 versus 329 g/mile for the Acura MDX. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
