Case Study

Jaguar Land Rover XJ_e Vehicle Demonstrator

Jaguar Land Rover (JLR) is at the centre of the UK automotive industry’s drive to deliver technical innovation in all areas of vehicle development. It is the UK’s largest investor in automotive green technology and is pushing the boundaries of research into the electrification of premium and luxury vehicles.

JLR’s latest example of this is the hybrid engineering research vehicle, Jaguar XJ_e, which will be demonstrated for the first time at this year’s LCV event at Millbrook Proving Ground. The Jaguar XJ_e is a new Plug-in Hybrid Electric Vehicle (PHEV) demonstrator developed in conjunction with leading UK technology companies, to help develop expertise for ultra-low carbon vehicles within the supply chain, under the Technology Strategy Board IDP4 competition.

The Jaguar XJ_e demonstrates how an advanced parallel plug-in hybrid design can deliver reductions in CO2 emissions of more than 70 per cent, without compromising vehicle performance. Capable of 0-100km/h (62mph) in under 6.5 seconds and with a limited top speed of 250km/h (150mph), the XJ_e achieves CO2 emissions of less than 75g/km.

The hybrid system uses a 69kW motor/generator and a 12.3kWh Lithium Ion battery pack, which can be fully charged by an external 240V domestic supply in around four hours. The battery pack can deliver a zero-emission electric-only range of 40km (25 miles).

The parallel hybrid design means that the XJ_e can run on petrol power, electric power, or a combination of the two, optimised by the car’s intelligent energy management system which selects the most efficient mode. The Jaguar XJ_e demonstrates how an advanced parallel plug-in hybrid design can deliver reductions in CO2 emissions of more than 70 per cent, without compromising vehicle performance.
