Kia Seltos vs Mitsubishi Outlander: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Kia Seltos burns about $2,000 of fuel annually against $2,200 for the Mitsubishi Outlander. That $200 yearly gap compounds to roughly $1,000 over five years and $1,600 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 Kia Seltos leads in both cycles — 29 mpg city and 35 mpg highway against 27 and 32 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Kia Seltos is recorded with 2 distinct engine configurations (2.0, SIDI), the Mitsubishi Outlander with 4 (2.4, 2.0, PHEV). Across 20 recorded Kia Seltos 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 Kia Seltos is offered with All-Wheel Drive, Front-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 Mitsubishi Outlander emits 97 g/mile of CO2 versus 283 g/mile for the Kia Seltos. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
