Kia Seltos vs Lincoln Nautilus: 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 $2,050 for the Lincoln Nautilus. That $50 yearly gap compounds to roughly $250 over five years and $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 versus highway split: the Lincoln Nautilus is the stronger commuter at 30 mpg city, while the Kia Seltos pulls ahead on the interstate at 35 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 Kia Seltos is recorded with 2 distinct engine configurations (2.0, SIDI), the Lincoln Nautilus with 3 (SIDI & PFI; Hybrid, SIDI & PFI, SIDI). Across 20 recorded Kia Seltos configurations and 28 for the Lincoln Nautilus, 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 Lincoln Nautilus with Part-time 4-Wheel Drive, All-Wheel Drive, Front-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 Kia Seltos emits 283 g/mile of CO2 versus 290 g/mile for the Lincoln Nautilus. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
