Audi Q7 vs Buick Encore: Specs Compared

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 $3,450 for the Audi Q7. That $1,450 yearly gap compounds to roughly $7,250 over five years and $11,600 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 20 and 27 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Audi Q7 is recorded with 4 distinct engine configurations (SIDI; Mild Hybrid, SIDI, SIDI & PFI), the Buick Encore with 4 (SIDI, SIDI; FFV, 1.4). Across 22 recorded Audi Q7 configurations and 47 for the Buick Encore, 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 Audi Q7 is offered with All-Wheel Drive, the Buick Encore 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 4WD and Small Sport Utility Vehicle 2WD 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 405 g/mile for the Audi Q7. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
