The Ford 4.4 TD is a diesel engine developed and built by Ford Motor Company. It is based on the Lion V6 Diesel and has a power output of 340 PS (250 kW; 335 hp) and 700 N⋅m (516 lb⋅ft) of torque. As with the other AJDs, it has a Compacted Graphite Iron block that reduces weight while increasing engine block strength. Its bore diameter and the stroke is 84 mm × 98.5 mm (3.31 in × 3.88 in), giving a displacement of 4.4 L; 266.5 cu in (4,367 cc).

The 4.4 L (4,367 cc) is built at Chihuahua Engine Plant in Chihuahua, Chihuahua, Mexico along with the 6.7L Ford Power Stroke Diesel engine available in Ford Super Duty trucks. Current application of the 4.4 L (4,367 cc) TD engine is the Land Rover Range Rover.

While in development, the 4.4 TD was rumored to be for use in the Ford F-150, Ford Expedition, and as an entry level diesel option for the Super Duty. No such option ever became available with Ford citing the reason as being a low demand for a vehicle with a $6000–$8000 premium over its gasoline models.
