Jaguar’s new 3.0-litre diesel engine is destined to be used by the Land Rover Discovery and Range Rover Sport models.
The engine, set to power the new Jaguar XF S, is a development of the 2.7-litre AJV6 currently used in the Land Rover Discovery. The new 3.0-litre V6 diesel will be available in 272bhp and 237bhp outputs.
It is still not known whether the revised engine will replace or supplement the existing 2.7-litre powerplant, which gets a twin-turbo set-up on Jaguars but a single turbocharger on Land Rover models.
The new engine won’t appear until facelifted versions of the Land Rover Discovery and Range Rover Sport arrive in September.
The facelifted Land Rover Discovery will take only the 237bhp unit, while the Range Rover Sport will be available only with the 272bhp engine and will benefit from a 66 per cent increase in torque, raised to 420lb ft.
There are no plans for Land Rover to use the new V6 elsewhere in its range, and will continue to use the V8 diesel engine in the facelifted Range Rover, also due in September.
