GMC Acadia vs Volvo XC90: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the GMC Acadia burns about $2,450 of fuel annually against $2,800 for the Volvo XC90. That $350 yearly gap compounds to roughly $1,750 over five years and $2,800 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 Volvo XC90 leads in both cycles — 26 mpg city and 30 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 GMC Acadia is recorded with 1 distinct engine configuration (SIDI), the Volvo XC90 with 4 (SIDI; Mild Hybrid, SIDI; PHEV, 2.0). Across 44 recorded GMC Acadia configurations and 43 for the Volvo XC90, 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 GMC Acadia is offered with All-Wheel Drive, Front-Wheel Drive, the Volvo XC90 with 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 Standard 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 Volvo XC90 emits 131 g/mile of CO2 versus 349 g/mile for the GMC Acadia. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
