The PSA XUD engine is a family of Diesel straight-4 internal combustion engines used in Citroën and Peugeot automobiles. The basic XU design was introduced in 1981 with the Peugeot 305.
The XUD was available with either SOHC or 12-valve DOHC heads. It was applied transversaly in front wheel drive vehicles only, tilted by 30°.
Displacement ranged between 1769 and 2138 cc, and all XU gasoline engines had a stroke of 88 mm (3.5 in) or 92 mm (3.6 in). The former was shared with the XU9. Bore sizes ranged from 80 mm (3.1 in) to 86 mm (3.4 in), some shared with other XU engines.
The XUD was replaced by the joint Ford/PSA DLD/DV family.
