Fuel economy is the measure of the efficiency of a vehicle. Efficiency is measured as a ratio between the fuel consumption and the distance that can be travelled.

Fuel economy and efficiency can be represented in two forms. The first form is the measure of the distance that can be travelled for a single unit of fuel volume, for instance miles per gallon.

The second form is to express the fuel volume consumed to travel a specific distance, for instance liters per 100 kilometers.
