Duratec ST

The 3.0 L, 226 hp V6 used in the Mondeo ST220 is called Duratec ST.

Duratec SE

The 3.0 L, 204 hp V6 in the Mondeo Titanium is called Duratec SE.

Duratec 35

The Duratec 35 (code-name Cyclone) is a new 3.5 liter V6 that will appear in 2005. It is an all-aluminum engine based on the Duratec 30, and adds variable valve timing, a feature already found on the Jaguar AJ30 and Mazda AJ versions of the 3.0. Its displacement can be increased to 3.8 liters, meaning a Duratec 38 could come soon after.

The aluminum block is made by Teksid in Alabama, while the heads come from Newmak in Mexico, and the crankshaft comes from Bharat Forge of India. The engine will be assembled in Lima, Ohio.

8 Cylinder

The Ford Yamaha V8 engine is a version of the 2.5 L V6 was produced with two additional cylinders (3.4 L V8) but was not called a Duratec officially.

12 Cylinder

The 6.0 L V12 used in Aston Martin cars is sometimes erroneously referred to as "essentially two 3.0 L V6 units bolted together". In reality, the engine is custom-built for Aston Martin by Cosworth Technology (both Aston Martin and Cosworth are owned by Ford) and while it uses some standard Duratec components, it is Cosworth's own design. Aston Martin use this engine in the DB7 Vantage, the V12 Vanquish and the DB9.

These engines will generally work with the CD4E, MTX-75 and Durashift gearboxes.
