The Jaguar AJ-V6 engine is a piston engine based on the Ford Duratec V6 engine.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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 Template:Cvt, Template:Cvt and Template:Cvt 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 Template:Cvt bore and stroke, and displaces Template:Cvt. Although it displaces nearly 2.1-litres, it is marketed as a "2.0". It produces Template:Cvt and Template:Cvt. 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 Template:Cvt. It shares the AJ20's Template:Cvt bore and is stroked to Template:Cvt, the same as the AJ30. It delivers Template:Cvt at 6800 rpm with Template:Cvt 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, Template:Cvt and Template:Cvt
- 2002–2006 Jaguar S-Type 2.5 (UK), Template:Cvt and Template:Cvt
AJ30
The AJ30 is the most common version, especially considering the Duratec 30. It has an Template:Cvt bore and shares the AJ25's Template:Cvt stroke, giving a displacement of Template:Cvt. In the X-Type, it produces Template:Cvt and Template:Cvt. 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, Template:Cvt and Template:Cvt
- 2002–2009 Jaguar X-Type, Template:Cvt and Template:Cvt
- 2003–2010 Jaguar XJ, Template:Cvt and Template:Cvt
- 2008–2011 Jaguar XF Template:Cvt and Template:Cvt
- 2000–2006 Lincoln LS
