Alfa Romeo Stelvio vs Toyota 4Runner: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota 4Runner burns about $2,650 of fuel annually against $3,050 for the Alfa Romeo Stelvio. That $400 yearly gap compounds to roughly $2,000 over five years and $3,200 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 versus highway split: the Toyota 4Runner is the stronger commuter at 23 mpg city, while the Alfa Romeo Stelvio pulls ahead on the interstate at 29 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 Alfa Romeo Stelvio is recorded with 1 distinct engine configuration (SIDI), the Toyota 4Runner with 4 (SIDI & PFI; Hybrid, SIDI & PFI, SIDI & PFI; with Stop-Start). Across 22 recorded Alfa Romeo Stelvio configurations and 42 for the Toyota 4Runner, 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 Toyota 4Runner with 4-Wheel Drive, Part-time 4-Wheel Drive, Rear-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 Alfa Romeo Stelvio emits 359 g/mile of CO2 versus 380 g/mile for the Toyota 4Runner. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
