The Jaguar AJ-V6 engine is a piston engine based on the Ford Duratec V6 engine.[2] The Duratec V6 was originally a Porsche design, purchased by the Ford Motor Company with Cosworth finishing the engineering to suit Ford's needs. 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 2099cc, 2495cc and 2967cc displacements.

The AJ-V6 engine has an aluminium engine block and Jaguar Cars designed aluminium DOHC cylinder heads. It uses sequential fuel injection, has 4 valves per cylinder 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.

AJ20

The AJ20 2099cc version has an NaN2NaN2 bore and stroke. Although it displaces nearly 20991NaN1, it is marketed as a "2.0". It produces 1570NaN0 and 1480NaN0. The compression ratio is 10.75:1.

This engine is used in the following vehicles:

AJ25

The AJ25 is a 2495cc version built. It shares the 2.1's 81.62NaN2 bore and is stroked to 79.52NaN2, the same as the 2967cc. It delivers 1930NaN0 at 6800 rpm with 1780NaN0 of torque at 3000 rpm from 10.3:1 compression.

This engine is used in the following vehicles:

AJ30

The AJ30 is a 2967cc version and is the most common, especially considering the Duratec 30. It has an 89mm bore and shares the 2.5's 79.52NaN2 stroke. In the X-Type, it produces 2280NaN0 and 2090NaN0. The Jaguar XF debuted a refined version of the AJ30 with continuously variable cam-phasing and variable geometry air intakes to increase power and broaden the powerband up to its 6800 rpm redline.

This engine is used in the following vehicles:
