The PSA XU series comprises a range of internal combustion engines utilized in Citroën and Peugeot vehicles, which dominated the mid-sized engine segment during the 1980s and 1990s.
Launched in 1981 with the Peugeot 305, the XU engines were available in SOHC or DOHC inline-4 configurations, featuring either two or four valves per cylinder and powered by petrol. These engines were mounted transversely in front-wheel-drive layouts, inclined at a 30° angle. Displacements varied from , with bore dimensions of . All variants incorporated aluminium cylinder heads; the blocks were generally cast from aluminium alloy and included removable cast iron wet liners, except for the XU10, which employed cast iron blocks with precision-machined bores. The first Citroën model to adopt this engine was the unit found in the Citroën BX (1982).
The XU engine lineup was eventually replaced by the more contemporary EW/DW series.
XU5
