Buick Encore vs Toyota 4Runner: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Buick Encore burns about $2,000 of fuel annually against $2,650 for the Toyota 4Runner. That $650 yearly gap compounds to roughly $3,250 over five years and $5,200 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 Buick Encore leads in both cycles — 30 mpg city and 33 mpg highway against 23 and 26 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Buick Encore is recorded with 4 distinct engine configurations (SIDI, SIDI; FFV, 1.4), the Toyota 4Runner with 4 (SIDI & PFI; Hybrid, SIDI & PFI, SIDI & PFI; with Stop-Start). Across 47 recorded Buick Encore 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 Buick Encore is offered with All-Wheel Drive, Front-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 2WD 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 Buick Encore emits 288 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.
