The PSA XU is a family of internal combustion engines used in Citroën and Peugeot automobiles. It became the dominant mid-size engine in Peugeot and Citroën products through the 1980s and 1990s.

The XU design was introduced in 1981 with the Peugeot 305. It was a SOHC or DOHC straight-4 design with two or four valves per cylinder, using petrol as fuel. It was applied transversely in front wheel drive vehicles only, tilted by 30°. Displacement ranged between 1580 and 1998 cc, and all XU gasoline engines had a bore of 83 mm (3.3 in) or 86 mm (3.4 in). The engine uses an all aluminium block and cylinder head with removable cast-iron wet-liners. Its first Citroën application was on the Citroën BX in 1983, where it appeared in 1580cc format.

The XU was replaced by the more modern EW/DW family.

XU5[edit]

The XU5 had a displacement of 1.6 L (1580 cc), with a bore of 83 mm (3.3 in) and a stroke of 73 mm (2.9 in). All XU5 engines were SOHC 2-valve per cylinder designs. It used either a single or double-barrel carburetor or fuel injection, depending on model. Output ranged from 80–115 PS (79–113 hp/59–85 kW).

The plastic timing covers for these engines have been discontinued and are notoriously difficult to find.
