The AJD series encompasses both V6 and V8 turbodiesel engines, featuring a completely new architecture and variable valve timing technology. These powerplants were developed by Ford of Europe to serve its affiliates Jaguar and Land Rover, as well as its collaborator PSA Group through the Gemini joint venture. Within Jaguar and Land Rover vehicles, these engines are referred to as the AJD-V6, while Citroën and Peugeot designate them as DT17/DT20. Both engine types share identical bore and stroke dimensions, with the V6 displacing and the V8 at . The V6 made its debut in 2004, complying with Euro IV emission regulations, followed by the V8 in 2006. In 2009, a DT20 variant emerged, derived from the DT17 platform. The V6 engine is utilized across a diverse lineup that includes the Citroën C5, Citroën C6, Land Rover Discovery, Range Rover, several Jaguar models, alongside the Ford Territory and the subsequent generation of the Ford Ranger.
Common construction
This engine family employs dual overhead camshafts (DOHC) combined with multi-valve setups, equipped with either single or twin turbochargers supported by air-to-air intercoolers. Its advanced compacted graphite iron (CGI) block contributes to a reduced dry weight of . Fuel is delivered via high-pressure common rail direct injection systems to optimize both performance and fuel economy.
Lion V6
The Land Rover-specific Lion V6 diesel engine emphasizes enhanced low-end torque tailored for off-road driving and towing applications by utilizing a large single turbocharger rather than a twin-turbo configuration. It incorporates an engine-driven cooling fan designed for prolonged operation under low-speed, heavy-load conditions typical in desert environments. Additional improvements include a sump with increased depth and refined baffles to preserve oil pressure during extreme vehicle angles, multi-layered sealing systems to guard against ingress of dust, mud, and water, along with a distinctive transmission bell housing bolt pattern. Constructed from compacted graphite iron, the Lion V6 is part of the Ford Duratorq family and is manufactured at Ford’s Dagenham facility; production reached 35,000 units between April and December 2004.
Replacing the earlier 2.7-litre unit, the 3.0-litre Gen III iteration features a sequential turbocharging arrangement and an upgraded common rail injection system employing piezo injectors positioned near their tips to minimize noise and fuel wastage. This configuration enhances fuel efficiency relative to its predecessor. The sequential turbocharger setup activates a smaller turbo at lower engine speeds and brings in a larger turbocharger once engine speed exceeds 2,800 rpm to boost output.
Jaguar evaluated this engine within its XK model but ultimately did not advance it to production. Land Rover’s 3.0-litre variants maintain the off-road modifications found on the 2.7-litre version and are engineered to operate on lower-grade fuels.

Lion V8
The 3.6-litre twin-turbo V8 diesel engine commenced manufacturing in April 2006 at Ford’s Dagenham facility; meanwhile, the 4.4-litre variant is produced at Ford’s Chihuahua plant in Mexico.
Although the 4.4-litre version was initially considered for Ford F-150 and Expedition models in the US market, it was eventually discontinued. Production of compacted graphite iron blocks began at Cleveland Engine Plant; however, Ford opted to implement a revised 3.0-litre Lion V6 equipped with a single turbocharger for its US truck lineup.
