MPG (miles per gallon)

MPG measures how many miles a vehicle travels on one gallon of fuel. It is the single most quoted efficiency number, and in the United States the official figures come from EPA testing, not from the manufacturer's marketing.

The EPA publishes three figures for each vehicle: city, highway, and combined. Your real-world result depends on speed, temperature, terrain, and driving style, so treat the ratings as a fair basis for comparison rather than a promise.
