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The 3.0-litre design, known as the Gen III, superseded the 2.7-litre, and uses turbochargers on a series-sequential system and has an uprated common rail injection system incorporating fuel injectors with piezo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

and unused fuel temperature over the 2.7-litre model. The sequential turbocharger system utilizes the smaller of the two turbos when the engine is running at low revolutions; once the engine has reached 2,800 rpm, the larger turbocharger is also used to pressurize the intake. 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.
