Ford 4.4 Turbo Diesel

The Ford 4.4 TD is a diesel V8 engine developed and built by Ford Motor Company. It has a power output of 340 PS and 700 Nm 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 stroke are 84x98.5 mm, giving a displacement of 4367 cc.

The 4367 cc is built at Chihuahua Engine Plant in Chihuahua City, Mexico, along with the 6.7L Ford Power Stroke Diesel engine available in Ford Super Duty trucks. The current (and only) application of the 4367 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 (to possibly compete with the also-rumored cancelled concept 4.5 L Duramax). No such option ever became available with Ford citing the reason as being in low demand for a vehicle with a $6000–$8000 premium over its gasoline models.
