The Jaguar (car) AJ-V6 Piston engine is a specialized version of Ford's Duratec 25/30 V6. 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 2.0 L, 2.5 L and 3.0 L displacements.
Jaguar's AJ-V6 engine has an aluminium engine block and aluminium DOHC cylinder heads. It uses SFI Fuel injection, has Multivalve with VVT, features fracture-split forged powder metal connecting rods and a one-piece cast Camshaft and has direct-acting mechanical bucket (DAMB) tappets, these design aspects differentiating the AJ-V6 from the Ford and Mazda versions.
