Kia Seltos vs Mercedes-Benz GLE-Class: 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 $3,150 for the Mercedes-Benz GLE-Class. That $1,150 yearly gap compounds to roughly $5,750 over five years and $9,200 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 and highway economy: the Kia Seltos leads in both cycles — 29 mpg city and 35 mpg highway against 23 and 29 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 Mercedes-Benz GLE-Class with 4 (SIDI; Mild Hybrid, SIDI; PHEV, SIDI). Across 20 recorded Kia Seltos 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 Kia Seltos 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 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.
