The Lion engine family was developed and manufactured at Ford's Dagenham Diesel Centre for use in PSA Peugeot Citroën vehicles (as DT17 as part of joint venture begun in 1999), Jaguar Cars (as the AJD-V6), and Land Rover vehicles. The engines share the same bore/stroke ratio, with the V6 displacing 2.7L and the V8 displacing 3.6L. The V6 was launched in 2004 and as of 2011 also serves in Ford Australia's Territory SUV; the V8 in 2006. The V6 engine meets the Euro IV emissions standards. A 3.0L was added in 2009 and is based on the 2.7L.

The engine family utilizes a high-tech DOHC with 24/32 valves, twin turbochargers with an air-to-air intercooler, and an innovative compacted graphite iron (CGI) block construction that leads to a low weight of 202 kg dry. High-pressure common rail direct injection completes the picture. Bore is 81 mm and stroke is 88 mm for the engine.
The V6 utilizes a 60° V configuration. Output is 147 to 152 kW (200 to 207 hp ECE) and up to 440 Nm (325 ft.lbf).
Land Rover version is called 'LR-TDV6 Diesel engine'. It has a single turbocharger, of a larger capacity than the twin-turbo design. This is to improve the engine's low-speed torque range for off-road and towing applications. It is also fitted with a very large, engine driven cooling fan to support low speed, but high load driving such as those that may be encountered in desert conditions. Other changes made to the Land Rover version of the engine over the Jaguar/Peugeot versions include a deeper high-capacity sump with improved baffles to maintain oil pressure at extreme off-road angles and multi-layered external seals to keep out dust, mud and water.
The engine is a member of the Ford Duratorq family of engines and is produced in Ford's Dagenham engine plant. 35,000 were produced from April through the end of 2004.
"Jaguar engineers were involved from the very beginning of the V6 diesel programme within the main project team of Ford Motor Company and PSA Peugeot - Citroen to help define the base engine specification and technologies necessary to deliver the high standards of power, refinement and drivability expected of a Jaguar," says the joint press release.
It is a version with 2,720 cc (166 cu in) displacement and 2 turbochargers. The engine block is made from compacted graphite iron.[1]
The family was superseded by AJ-V6D Gen III engines.
It is a family of twin turbocharged engines introduced with 2010 model year Jaguar Land Rover vehicles. The Gen III is produced in a larger capacity than the original version, being a 3-litre design. It uses 'parallel serial' turbocharger system. The block is made from compact graphite iron. The common rail injection system includes 2000bar injectors. Emission is reduced via common rail injection, exhaust gas recirculation, and diesel particulate filters.
The parallel sequential system uses only the larger variable geometry turbocharger when engine is running at low RPMs. Once the engine has reached 2800 rpm, the smaller fixed turbocharger is used to push boosted air to the intake port of the larger turbocharger, before the boosted air from the smaller turbocharger is redirected to intercooler 300 milliseconds later, when the smaller turbocharger is fully operational.
Fuel injector includes a piezo crystal fitted nearer to the tip to reduce engine noise, and a metering mode to reduce oversupplying of fuel that increases unused fuel temperature and energy consumption.
The Gen III is standard fitment in the Land Rover Discovery 4 and as the smallest diesel available in the Range Rover Sport. In Land Rover products the engine is badged as the 3.0 TDV6. Jaguar fit the Gen III to the XF and XJ models. Jaguar tested versions of the XK fitted with the engine but did not carry the project on to production. As with the 2.7-litre engine the Land Rover variants feature a viscous-coupled cooling fan, larger and deeper oil sumps, improved dust and water sealing and a unique calibration of the engine's electronics to allow the use of low-quality fuels.
The 3.6 L V8 is built at Ford Dagenham by Ford of Europe. It is a twin-turbocharged Diesel V8 producing 272 PS (268 hp/200 kW) and 640 N·m (472 ft·lbf). Production began in April 2006.
Much speculation in the United States has focused on this engine as a possible Diesel entrant in the F-150 pickup truck and Expedition SUV.[2] It was announced that the new F150 engine will be based on this engine and enlarged to 4.4L. The Cleveland Engine plant recently began small-scale production of the exotic compacted graphite iron (CGI) used in the block's construction, leading many to expect production of the engine there.
