TU3
The TU3 has a displacement of 1360 cc, with a bore of 75 mm and a stroke of 77 mm. This engine has been one of the most used by the PSA Group, with applications in superminis, compacts and midsize cars, including a stint in competition use in the Citroën AX GT Cup and the Citroën AX GTI Cup, held in many European countries throughout the early 1990s in both circuit racing and rallying.
In its early years, it was available with either a single or double barrel carburetor, with fuel injection introduced in 1990 for the AX GTI and 106 XSi, capable of delivering 100 PS (73.5 kW) at 6600 rpm. The carburated versions gave way to fuel injection in 1992, while the sports version was retired in 1996.
