Lion V6
To improve the engine's low-speed torque range for off-roading and towing applications, the Land Rover variant utilised a large capacity single-turbocharger, rather than use the twin-turbo design; in addition the engine is fitted with a large engine driven cooling fan to support low speed, high load driving as may be encountered in desert conditions. Furthermore, the Land Rover variant of the Lion V6 includes a deeper, high capacity sump with improved baffles to maintain oil pressure at off-roading extreme angles and multi-layered seals to keep dust, mud and water at bay and different transmission bell housing bolt pattern. The Lion V6 – constructed from compacted graphite iron[1] – is a member of the Ford Duratorq family and is produced at Ford's Dagenham engine plant; 35,000 engines were produced from April to December 2004.
The 3.0-litre design, known as the Gen III, superseded the 2.7-litre, and uses turbochargers on a series-sequential system and has an uprated common rail injection system incorporating fuel injectors with piezo crystals fitted nearer to the tip to reduce engine noise and a metering mode to reduce oversupplying fuel, decreasing
Jaguar tested fitting the engine to its XK model but didn't carry the project over to production.
The 3.0-litre variants used by Land Rover feature the 2.7-litre's off-roading adaptations plus calibration of the engine's electronics to allow the use of low-quality fuels.

Lion V8
Built at Ford's Dagenham engine plant in Essex, the 3.6-litre V8 twin-turbo diesel engine began production in April 2006. The 4.4 L variant is built in Ford's Chihuahua Engine plant in Mexico.
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 F-150 engine was to be based on this engine and enlarged to 4.4 L, but that program was later cancelled. 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. Ultimately, Ford went with the 3.0 L Lion V6 modified for US truck use, utilising a single turbocharger.
