Audi SQ5 vs GMC Yukon: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the GMC Yukon burns about $3,250 of fuel annually against $3,300 for the Audi SQ5. That $50 yearly gap compounds to roughly $250 over five years and $400 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 GMC Yukon is the stronger commuter at 21 mpg city, while the Audi SQ5 pulls ahead on the interstate at 28 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 Audi SQ5 is recorded with 1 distinct engine configuration (SIDI), the GMC Yukon with 4 (3.0, SIDI, SIDI; Stop-Start). Across 20 recorded Audi SQ5 configurations and 164 for the GMC Yukon, 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 SQ5 is offered with All-Wheel Drive, 4-Wheel Drive, the GMC Yukon with 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 4WD 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 Audi SQ5 emits 382 g/mile of CO2 versus 437 g/mile for the GMC Yukon. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
