Design
The Prince family shares its basic block dimensions with the previous PSA TU engine family, but with bore and stroke measurements identical to the Tritec engine family. Some of the engineering was provided by BMW, including their Valvetronic variable valve lift system on the intake side. Other features include on-demand oil and water pumps. Gasoline direct injection with a twin-scroll turbocharger will be optional.
All Prince engines will share 84 mm (3.3 in) cylinder spacing and a 77 mm (3 in) bore. The engine features a two-piece "bedplate" aluminum crankcase for extra stiffness.
