Audi Q5 vs Chevrolet Suburban: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Audi Q5 burns about $2,800 of fuel annually against $3,250 for the Chevrolet Suburban. That $450 yearly gap compounds to roughly $2,250 over five years and $3,600 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 Audi Q5 leads in both cycles — 25 mpg city and 30 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 Audi Q5 is recorded with 4 distinct engine configurations (SIDI, SIDI; Mild Hybrid, SIDI; PHEV), the Chevrolet Suburban with 4 (3.0, SIDI, SIDI; Stop-Start). Across 36 recorded Audi Q5 configurations and 72 for the Chevrolet Suburban, 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 Q5 is offered with All-Wheel Drive, the Chevrolet Suburban 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 Q5 emits 148 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.
