Chevrolet Suburban vs Subaru Forester: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Subaru Forester burns about $1,750 of fuel annually against $3,250 for the Chevrolet Suburban. That $1,500 yearly gap compounds to roughly $7,500 over five years and $12,000 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 Subaru Forester leads in both cycles — 35 mpg city and 34 mpg highway against 21 and 27 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Chevrolet Suburban is recorded with 4 distinct engine configurations (3.0, SIDI, SIDI; Stop-Start), the Subaru Forester with 3 (SIDI, SIDI; Hybrid, 2.5). Across 72 recorded Chevrolet Suburban configurations and 29 for the Subaru Forester, 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 Chevrolet Suburban is offered with 4-Wheel Drive, Rear-Wheel Drive, the Subaru Forester with 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 Standard 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 Subaru Forester emits 255 g/mile of CO2 versus 437 g/mile for the Chevrolet Suburban. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
