Cadillac Escalade vs Mercedes-Benz GLE-Class: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Mercedes-Benz GLE-Class burns about $3,150 of fuel annually against $3,450 for the Cadillac Escalade. That $300 yearly gap compounds to roughly $1,500 over five years and $2,400 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 GLE-Class leads in both cycles — 23 mpg city and 29 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 Cadillac Escalade is recorded with 3 distinct engine configurations (SIDI, 3.0, SIDI; Stop-Start), the Mercedes-Benz GLE-Class with 4 (SIDI; Mild Hybrid, SIDI; PHEV, SIDI). Across 46 recorded Cadillac Escalade 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 Cadillac Escalade is offered with 4-Wheel Drive, Rear-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 Standard 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 437 g/mile for the Cadillac Escalade. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
