Is the 2015 Aston Martin Vanquish good on gas?

At up to 16 MPG combined, the 2015 Aston Martin Vanquish is worse than average for a Minicompact Cars — that class averages about 21.0 MPG across 1,649 EPA-tested versions, so it's on the thirsty side 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.

EPA updated its fuel-economy equations again for model year 2017 — mostly affecting hybrids and turbocharged engines — and recalculated 2011-2016 ratings to match, in some cases 1-2 MPG lower. The number above already reflects that update.

At today's AAA national average price — $4.68/gal for premium gas as of 2026-07-05 — the most efficient trim runs about $4,388/year (roughly $366/month, about $29.25 per 100 miles) at the EPA's assumed 15,000 miles/year, using an estimated 938 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 →

Where the EPA lists premium, that’s the fuel the maker specified for the mileage test — many such engines run on regular with slightly less power/MPG. Whether premium is required or just recommended is an owner’s-manual detail the EPA dataset omits, so we don’t guess it.
