EPA:

1. Acronym for "Energy Protection Agency."
   Also See:
   EPA fuel economy.
2. Acronym for "Environmental Protection Agency" which is responsible for recommending environmental legislation and in the automotive sphere produces test cycles and estimates fuel economy

EPA estimate:

An American organization (Energy Protection Agency) which determines the fuel consumption of various vehicles. It takes into account city and highway driving. These figures may be helpful in comparing one vehicle against another. Your vehicle can greatly exceed these estimates with sensible driving, the use of cruise control obeying the speed limits avoiding rapid starts, coasting long before a stop light or sign.

EPA fuel economy:

Laboratory fuel economy tests administered by the Environmental Protection Agency (EPA) using simulated weight and drag to re-create real driving conditions. The city fuel-economy test, also used to test emissions compliance is based on a drive through typical Los Angeles urban traffic of the 1980s. Such conditions in LA are no longer present. The highway test uses a higher, steadier speed averaging 79.5 kph (49.4 mph).
