New Defender Dieselmotor D300 MHEV

The current 6-cylinder engines of the so-called Ingenium series are an in-house development of Jaguar Land Rover and are produced and tested in England at the Wolverhampton plant. The Ingenium engines thus replace the purchased engines from Ford/PSA and BMW with their own production. Only in the area of 8-cylinder engines is there still cooperation between Jaguar Land Rover and BMW.

The engines are made entirely of aluminum and in the D300 variant have a sequential biturbo as well as an electrically driven compressor fed from the 48V network, which bridges the small turbo gap. Jaguar Land Rover paid particular attention to reducing friction in the system during development, so that roller-bearing crankshafts are also used, for example, with astonishingly low friction values.

The diesel engine in the variant provides a maximum torque of brute 650Nm at very low revs from 1,500 rpm, making it a very powerful engine for off-road or towing without having to resort to high revs. The acceleration of the New Defender with this engine and a value of 7s from 0 to 100km/h is on an amazing level.

In addition, the engine has a mild hybrid system, which can recuperate energy during braking, store this energy temporarily in a battery or alternatively provide the energy when starting the engine or for the compressor. This reduces fuel consumption while improving performance figures.
