Flexible-fuel vehicle

A flexible-fuel vehicle (FFV) or dual-fuel vehicle (also sometimes called only flex-fuel) is an automobile that can typically alternate between two sources of fuel.

A common example is a vehicle that can accept gasoline mixed with varying levels of bioethanol (gasohol).

Some cars carry a natural gas tank and one can switch from gasoline to gas.
