The most fuel-efficient 2026 V8 is the Mercedes-Benz S-Class at 20 mpg combined (≈$3,850/yr in fuel). Next best: BMW 7 Series (20 mpg) and BMW 8 Series (19). The average V8 here gets about 17 mpg — versus 24 mpg for all new cars.
Since 2010 the average V8 has gone from 16.5 to 15.8 mpg — a decline of 4%, one of the few classes that got thirstier. And the last five years actually gave back 0.7 mpg. The single best V8 we have on record still dates to 2010 at 22 mpg. Within the current ranking the gap runs from 15 to 20 mpg — picking the wrong end of this list costs roughly $660 a year in fuel at 12,000 miles. The typical V8 here reads 17 mpg, 9 mpg worse than an average vehicle — a difference of about $806 a year. Calculated from ForCar's copy of the EPA fuel-economy database.

How V8 Cars changed over 17 years
Average EPA combined mpg of every V8 sold in the US, model year by model year. A ranking shows you today; this shows whether the class is actually getting better — and most published V8 lists never ask:
Each point is the mean of every V8 variant EPA rated that model year (at least 12 per year, 3,277 in total). Averages move slowly because they include the whole class, not just the leaders — 2027's best V8 reaches 19 mpg, well ahead of the 15.8 average.
MPG is a number. Dollars per year is the answer.
- Fuel profile built from your actual mileage and local prices
- Fuel tracker: what you really spend, month by month
- Insurance and fuel folded into 5-year cost to own
- Compare any two cars on total cost, not sticker price
- No ads, no tracking — and much more
