[1] The inline-four engines are sold under the DuraTorq TDCi name by Ford, and as the HDi by Citroën and Peugeot.

The DV5 with an intercooled variable-geometry turbocharger (for example, Garrett GT1544V), and with Diesel particulate filter is Euro 6.2 compliant.

The first DV6 has a DOHC 16-valve design, with an intercooled variable-geometry turbocharger (for example, Garrett GT1544V), and with Diesel particulate filter is Euro 5 compliant.

It is only a DLD by name, since it is completely unrelated to the 1.4/1.6 units, and is derived from Ford's own 1.8 8-valve Endura-D engine that saw service through the 1980s and 1990s.

The Endura-D was heavily revised and updated with a variable-vane turbocharger and a Delphi high-pressure common rail injection system and relaunched in 2001 as the DuraTorq TDCi, with the original engine being rebadged 'DuraTorq TDDi'.
