The straight-4 engines are sold under the Duratorq TDCi name by Ford, and as the HDi by Citroën and Peugeot. These are part of the DLD family. Mazda also uses the DLD engine in the Mazda2 and the Mazda3, calling it the MZ-CD or CiTD. The Ford/PSA joint-venture for the production of the DLD was announced in September, 1998.
Officially, there are two families of engines in the range:
- The 1.4L is generally nonintercooled
- The 1.5L derived from the 1.6L
- The 1.6 L always intercooled
Ford later added their unrelated 1.8 L DLD-418 engine to the DLD family, though it is properly part of the Ford Endura engine family.
