What every car burns
A reference built from the federal fuel economy record. Every nameplate gets one page covering all of its model years, every configuration EPA tested, and what those ratings cost at the pump.
Start with the car
If you know the nameplate, it has its own page: see every rating on record, how the number moved between model years, and where it stood against the rest of its class each year. Browse all 58 makes →
Start with a class
Comparing across brands instead? The 29 EPA classes each have a ranked page, best combined rating to worst, with what the class median costs over a year.
Start with where you drive
State motor fuel taxes range from 8.0 cents a gallon in Alaska to 57.6 cents in Pennsylvania. The gas tax page ranks all 51 jurisdictions and shows what the spread is worth over a year.
How these pages are built
Every number here comes from the federal fuel economy record or the federal motor-fuel tax table. Nothing is written by a language model and nothing is scraped from a retailer. Where a figure is computed — gallons a year, cost at the pump, class rank — the arithmetic is shown on the page so you can check it. More on the method →
