Chevrolet Suburban 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 $3,250 for the Chevrolet Suburban. That $1,050 yearly gap compounds to roughly $5,250 over five years and $8,400 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 Mitsubishi Outlander leads in both cycles — 27 mpg city and 32 mpg highway against 21 and 27 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Across 72 recorded Chevrolet Suburban 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 Chevrolet Suburban is offered with 4-Wheel Drive, Rear-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 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 Mitsubishi Outlander emits 97 g/mile of CO2 versus 437 g/mile for the Chevrolet Suburban. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
