At up to 20 MPG combined, the 2009 Audi Q7 is better than average for a Sport Utility Vehicle - 4WD — that class averages about 17.3 MPG across 2,078 EPA-tested versions, so it's a good pick on fuel for its size.
Real-world MPG vs the EPA number
The EPA figures above come from a standardized dynamometer test, not the open road — real-world MPG typically runs a bit lower depending on your driving, climate and terrain. That's true of every car on this site, old or new.
At today's AAA national average price — $4.78/gal for diesel gas as of 2026-07-05 — the most efficient trim runs about $3,585/year (roughly $299/month, about $23.90 per 100 miles) at the EPA's assumed 15,000 miles/year, using an estimated 750 gallons a year. We don't estimate a cost-per-fill since exact tank size isn't in the public EPA dataset, but the per-100-mile figure scales to any tank. Current national average gas prices →
