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 third annual Royal Automotive Club Future Car Challenge from Brighton to London on November 3rd, 2012.

Jaguar Land Rover PLC entered three of its Jaguar XJ_e PHEV engineering research cars into the event, and achieved a best-in-class rating. The XJ_e used only 0.31 gallons of gas and 11 kilowatt hours (kWh) of electricity as it drove a 63 mile course, which equates to approximately 112 MPGe (miles per gallon equivalent). According to the US Department of Energy’s fuel economy information website, the Jaguar XJ_e would tie with Mitsubishi i-MiEV as the vehicle with the highest MPGe commercially available.

The RAC Future Car Challenge is one of three flagship events owned by the Royal Automobile Club that took place on the weekend of November 3rd and 4th, 2012. The other two were the London to Brighton Veteran Car Run, the world’s longest running motoring event, and the Regent Street Motor Show. Together they make for the largest free-for-spectators annual motoring event in the UK.

“The three experimental XJ_e vehicles were brand new so this event was their first drive in real-world conditions,” Pete Richings, director of Jaguar Land Rover Hybrids and Electrification, said. “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 innovative XJ_e project is led by Jaguar Land Rover as part of its strategy to develop best-in-class low-carbon premium products. Partly funded by the United Kingdom government’s Technology Strategy Board through the REEVolution project, this advanced research vehicle has been engineered in partnership with leading UK technology companies to help develop expertise for ultra-low carbon vehicles within the supply chain.
