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 1580and, and all production XU gasoline engines had a bore of 83or. The engine uses an aluminium cylinder head in all models. All models' blocks are made, except XU10, in cast aluminium alloy with removable cast iron wet cylinder liners. XU10 blocks are made in cast iron, with bores machined directly in the block, without removable cylinder liners. Its first Citroën application was on the Citroën BX in 1982, where it appeared in 1580cc format.
The XU was replaced by the more modern EW/DW family.
The XU5 had a displacement of 1580cc, with a bore and a stroke of NaNmm. All XU5 engines were SOHC 2-valve per cylinder designs. They used either a single or double-barrel carburetor, or fuel injection, depending on model. Output ranges from NaN0NaN0.

The XU8 had a displacement of 1775cc, with a bore and a stroke of NaNmm.[1] The only engine in this family is the 16-valve DOHC turbocharged XU8 T which was fitted to the Peugeot 205 Turbo 16.
The XU9 was the predecessor to the XU10 and had an aluminum block with wet iron liners. It had a displacement of 1905cc, with a bore and a stroke of NaNmm. Many versions were produced, from a double-barrel carburetted 8-valve to a 16-valve DOHC fuel injected model. Output ranged from NaN0NaN0.
