The Jaguar AJ-V6 engine is a piston engine based on the Ford Duratec V6 engine. The Duratec V6 was originally designed by Porsche, under contract to Ford, using a proprietary Cosworth cylinder head design to meet 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 2099 cc, 2495 cc and 2967 cc displacements.
The AJ-V6 engine has an aluminium engine block. Its aluminium DOHC cylinder heads were designed by Jaguar Cars. 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 — features that differentiate the AJ-V6 from the Ford and Mazda versions.
AJ20
The AJ20 version has an 81.6 × bore and stroke, and displaces 2099 cc. Although it displaces nearly 2.1-litres, it is marketed as a "2.0". It produces 157 hp and 148 lbft. The compression ratio is 10.75:1.
This engine is used in the following vehicles:
- Jaguar X-Type 2.0 (UK)
AJ25
The AJ25 displaces 2495 cc. It shares the AJ20's 81.6 mm bore and is stroked to 79.5 mm, the same as the AJ30. It delivers 193 hp at 6800 rpm with 178 lbft of torque at 3000 rpm with 10.3:1 compression.
This engine is used in the following vehicles:
- 2001–2009 Jaguar X-Type 2.5, 193 hp and 180 lbft
- 2002–2006 Jaguar S-Type 2.5 (UK), 201 hp and 185 lbft
AJ30
The AJ30 has an 89 mm bore and shares the AJ25's 79.5 mm stroke, giving a displacement of 2967 cc. In the X-Type, the engine produces 228 hp and 209 lbft. 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:
- 2000–2008 Jaguar S-Type, 240 hp and 221 lbft
- 2002–2009 Jaguar X-Type, 228 hp and 209 lbft
