Jaguar Land Rover’s green technology being developed for its cars of the future has received recognition in the third RAC Future Car Challenge from Brighton to London.

The Jaguar XJ_e experimental plug-in hybrid was awarded Most Energy Efficient Luxury Car Prototype and Technical Panel’s Award of Merit at the annual industry challenge.

Jaguar Land Rover entered three of its Jaguar XJ_e PHEV engineering research cars into the event, resulting in a best-in-class rating, using just 1.2 litres of petrol and 11kWh of electricity over a 63 mile course, equating to an equivalent fuel consumption of approximately 112 miles per gallon.

The XJ_e project is led by Jaguar Land Rover as part of its strategy to develop best-in-class low-carbon premium products.

Part funded by the UK Government’s Technology Strategy Board, the XJ-e has been engineered in partnership with UK technology companies to help develop expertise for ultra-low carbon vehicles within the supply chain.

Pete Richings, director, Jaguar Land Rover Hybrids & Electrification, said: “The three experimental XJ_e vehicles were brand new so this event was their first drive in real-world conditions.

“They performed faultlessly and delivered performance that exceeded our expectations, a tribute to our engineering team who prepared them.

“Events like this help us not only to understand the technical challenges involved but also provide an opportunity to showcase promising solutions.”

The Jaguar XJ_e PHEV utilise a specially developed two-litre turbocharged engine coupled with a 69kW electric motor and a 12.3kWh lithium-ion battery, instead of the five-litre V8 of the standard XJ.

The car can achieve a range of about 25 miles in all-electric mode and a maximum electric mode top speed of 75mph. Performance estimates for the Jaguar XJ_e are fuel economy of 87 miles per gallon and a top speed of 150mph. Tailpipe emissions are 75g/km – a 70 per cent improvement compared to the standard Jaguar XJ.
