The '''Jaguar AJ-V6 engine''' is a [[piston engine]] based on the [[Ford Duratec V6 engine]].<ref>{{cite web|url=https://performanceparts.ford.com/download/pdfs/EngineHistory.pdf | title=Ford Racing Engine History | date=July 2018}}</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 {{cvt|2099|cc|L|1|order=flip}}, {{cvt|2495|cc|L|1|order=flip}} and {{cvt|2967|cc|L|1|order=flip}} displacements.

The AJ-V6 engine has an aluminium engine block and [[Jaguar Cars]] designed aluminium [[DOHC]] cylinder heads. It uses [[sequential fuel injection]], has [[Multi-valve#Four valves|4 valves per cylinder]] with [[Variable valve timing|VVT]], features fracture-split forged powder metal [[connecting rod]]s 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''' {{cvt|2099|cc|L|1|disp=flip}} version has an {{cvt|81.6x66.8|mm|in|2}} [[bore (engine)|bore]] and [[stroke (engine)|stroke]]. Although it displaces nearly {{convert|2099|cc|L|1|disp=flip}}, it is marketed as a "2.0". It produces {{cvt|157|hp|kW PS|0}} and {{cvt|148|lbft|Nm|0}}. The [[compression ratio]] is 10.75:1.

This engine is used in the following vehicles:
* [[Jaguar X-Type]] 2.0 (UK)

==AJ25==
The '''AJ25''' is a {{cvt|2495|cc|L cuin|1|disp=flip}} version built. It shares the 2.1's {{cvt|81.6|mm|in|2}} bore and is stroked to {{cvt|79.5|mm|in|2}}, the same as the {{cvt|2967|cc|L|1|disp=flip}}. It delivers {{cvt|193|hp|kW PS|0}} at 6800&nbsp;rpm with {{cvt|178|lbft|Nm|0}} of torque at 3000&nbsp;rpm from 10.3:1 compression.

This engine is used in the following vehicles:
* 2001-2009 [[Jaguar X-Type]] 2.5, {{cvt|193|hp|kW PS|0}} and {{cvt|180|lbft|Nm|0}}
* 2002-2006 [[Jaguar S-Type (1999)|Jaguar S-Type]] 2.5 (UK), {{cvt|201|hp|kW PS|0}} and {{cvt|185|lbft|Nm|0}}

==AJ30==
The '''AJ30''' is a {{cvt|2967|cc|L|1|disp=flip}} version and is the most common, especially considering the [[Ford_Duratec_V6_engine#3.0_L|Duratec 30]]. It has an {{cvt|89|mm|in}} bore and shares the 2.5's {{cvt|79.5|mm|in|2}} stroke. In the X-Type, it produces {{cvt|228|hp|kW PS|0}} and {{cvt|209|lbft|Nm|0}}. 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&nbsp;rpm redline.

This engine is used in the following vehicles:
* 2000-2008 [[Jaguar S-Type (1999)|Jaguar S-Type]], {{cvt|240|hp|kW PS|0}} and {{cvt|221|lbft|Nm}}
* 2002-2009 [[Jaguar X-Type]], {{cvt|228|hp|kW PS|0}} and {{cvt|209|lbft|Nm|0}}
* 2003-2010 [[Jaguar XJ (X350)|Jaguar XJ]], {{cvt|237|hp|kW PS|0}} and {{cvt|216|lbft|Nm|0}}
* 2008-2011 [[Jaguar XF]] {{cvt|240|hp|kW PS|0}} and {{cvt|221|lbft|Nm|0}}
* 2000-2006 [[Lincoln LS]]
