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 — $4.68/gal for premium gas as of 2026-07-05 — the most efficient trim runs about $2,421/year (roughly $202/month, about $16.14 per 100 miles) at the EPA's assumed 15,000 miles/year, using an estimated 517 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 →
