How this is worked out
Cost per mile is the fuel price over the combined MPG of the version you pick, at the price and mileage you enter. Where a version requires premium, it is costed at the premium price — that is a real and permanent difference between two cars wearing the same badge.
Every figure comes from the U.S. EPA's public fuel economy data. We add no estimates of our own; a missing number shows as a dash rather than a guess.
Add your numbers
Federal data has at most a handful of owners per car and nothing at all on servicing. If you own one, send what you actually get. It goes on this page with the sample size next to it.
Your car's real number
Every figure on this page is an EPA lab rating. What your car actually does depends on your roads, your right foot, and its maintenance history. Carvico calculates your true MPG from your own fill-ups — kept completely private on your iPhone and iCloud.
