Mercedes-Benz GLC-Class vs Mitsubishi Outlander: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Mitsubishi Outlander burns about $2,200 of fuel annually against $2,600 for the Mercedes-Benz GLC-Class. That $400 yearly gap compounds to roughly $2,000 over five years and $3,200 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 Mitsubishi Outlander is the stronger commuter at 27 mpg city, while the Mercedes-Benz GLC-Class pulls ahead on the interstate at 33 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 Mercedes-Benz GLC-Class is recorded with 3 distinct engine configurations (SIDI; Mild Hybrid, SIDI; PHEV, SIDI), the Mitsubishi Outlander with 4 (2.4, 2.0, PHEV). Across 72 recorded Mercedes-Benz GLC-Class configurations and 88 for the Mitsubishi Outlander, 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 GLC-Class is offered with Rear-Wheel Drive, All-Wheel Drive, 4-Wheel Drive, the Mitsubishi Outlander with 4-Wheel Drive, Front-Wheel Drive, 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 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 GLC-Class emits 84 g/mile of CO2 versus 97 g/mile for the Mitsubishi Outlander. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
