Audi Q3 vs Hyundai Santa Fe: what the numbers mean

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Hyundai Santa Fe burns about $1,700 of fuel annually against $2,350 for the Audi Q3. That $650 yearly gap compounds to roughly $3,250 over five years and $5,200 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 Hyundai Santa Fe leads in both cycles — 37 mpg city and 36 mpg highway against 23 and 30 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Audi Q3 is recorded with 1 distinct engine configuration (SIDI), the Hyundai Santa Fe with 4 (SIDI & PFI, SIDI; Hybrid, 1.6). Across 21 recorded Audi Q3 configurations and 90 for the Hyundai Santa Fe, 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 Q3 is offered with All-Wheel Drive, Front-Wheel Drive, the Hyundai Santa Fe 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 Small Sport Utility Vehicle 4WD and Small 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 Hyundai Santa Fe emits 111 g/mile of CO2 versus 346 g/mile for the Audi Q3. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
