Jaguar unveiled their new technology study based on the XJ limousine at the Goodwood Festival of Speed. The new XJ_e was created to exhibit Jaguar-Land Rover's (JLR) capabilities and future plans in theory which is that the concept's plug-in hybrid drivetrain can be used in most of the group's models.

The XJ_e project was part funded by the UK Government’s Technology Strategy Board through the REEVolution project, and engineered in partnership with several UK technology companies "to help develop expertise for ultra-low carbon vehicles within the supply chain".

The car is fitted with a parallel plug in hybrid electric vehicle system, combining the JLR's 2.0 litre turbocharged direct injection petrol engine with a hybridised 8 speed automatic transmission for a combined output of 329hp.

The hybrid system makes use of a 69kW motor/generator and a 12.8kWh Lithium Ion battery pack, which can be fully charged by a 240V domestic supply in about four hours.

Jaguar says the XJ_e can run on pure electricity for up to 40km (25miles), on gasoline power alone, or a combination of both.
