GMC Acadia vs Infiniti QX60: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Infiniti QX60 burns about $2,350 of fuel annually against $2,450 for the GMC Acadia. That $100 yearly gap compounds to roughly $500 over five years and $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 versus highway split: the Infiniti QX60 is the stronger commuter at 26 mpg city, while the GMC Acadia 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 GMC Acadia is recorded with 1 distinct engine configuration (SIDI), the Infiniti QX60 with 4 (SIDI & PFI, SIDI, 2.5). Across 44 recorded GMC Acadia configurations and 30 for the Infiniti QX60, 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 Infiniti QX60 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 Infiniti QX60 emits 341 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.
