The XU is a family of petrol engines used in Citroën and Peugeot cars that became the dominant mid-size engine of both marques through the 1980s and 1990s. The design arrived in 1981 with the Peugeot 305 and reached Citroën in the BX in 1982. It is a straight-four with one or two overhead camshafts and two or four valves per cylinder, mounted across the car and tilted by 30 degrees. Displacement ran from 1.6 to 2.0 litres in the XU5, XU7, XU8, XU9 and XU10. All use an aluminium head, and all blocks are aluminium with wet iron liners except the XU10, which has a cast iron block. The only XU8 was the turbocharged 16 valve engine of the Peugeot 205 Turbo 16, and the EW and DW family replaced the XU.
