The Jaguar AJ-V6 engine is a piston engine based on the Ford Duratec V6 engine. The Duratec V6 was originally a Porsche design, purchased by the Ford Motor Company with a proprietary Cosworth cylinder head design to suit Ford's design brief. One notable addition is the use of variable valve timing, a feature also shared with Mazda's version of the engine. It is available in 2.1 L (2,099 cc), 2.5 L (2,495 cc) and 3.0 L (2,967 cc) displacements.
The AJ-V6 engine has an aluminium engine block and Jaguar Cars designed aluminium DOHC cylinder heads. Using sequential fuel injection, it has 4 valves per cylinder with VVT; fracture-split forged powder metal connecting rods; one-piece cast camshaft; and direct-acting mechanical bucket (DAMB) tappets — these features aspects differentiating the AJ-V6 from the Ford and Mazda versions.
