The term Duratec can be confusing to many people because in Europe, all Ford gasoline engines are considered to be Duratec. In North America however, only the dual overhead cam engines carry the Duratec name.

For the US market, Duratec is a family of 4, 6 and 12 cylinder gasoline engines used primarily for Ford, Mazda, Lincoln, and Mercury vehicles. The original Duratec was the 2.5L V6 as found in the Mondeo. With the introduction of the 2000 Mondeo, the 1.8L and 2.0L power-plants were converted to Duratecs.
