Alfa Romeo Stelvio vs Kia Sorento: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Kia Sorento burns about $1,650 of fuel annually against $3,050 for the Alfa Romeo Stelvio. That $1,400 yearly gap compounds to roughly $7,000 over five years and $11,200 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 Sorento leads in both cycles — 39 mpg city and 36 mpg highway against 22 and 29 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Alfa Romeo Stelvio is recorded with 1 distinct engine configuration (SIDI), the Kia Sorento with 4 (SIDI; Hybrid, SIDI; PHEV, SIDI & PFI). Across 22 recorded Alfa Romeo Stelvio configurations and 74 for the Kia Sorento, 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 Alfa Romeo Stelvio is offered with All-Wheel Drive, Rear-Wheel Drive, the Kia Sorento with 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 Kia Sorento emits 105 g/mile of CO2 versus 359 g/mile for the Alfa Romeo Stelvio. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
