Jaguar Land Rover (JLR) will display the XJ_e plug-in hybrid engineering research vehicle at the Goodwood Festival of Speed. The XJ_e demonstrates how an advanced parallel plug-in hybrid design can deliver reductions in CO2 emissions of more than 70%, without compromising vehicle performance.
The XJ_e combines the lightweight aluminium vehicle structure from the Jaguar XJ with a plug-in hybrid electric vehicle (PHEV) system, featuring the 2.0-liter turbocharged direct-injection gasoline engine which powers the Range Rover Evoque and a hybridized 8-speed automatic transmission. The hybrid system uses a 69 kW motor/generator from EVO Electric and a Li-ion battery pack from Axeon.

The 12.3 kWh, 307 V Li-ion system weighs in at 159 kg. The battery pack makes use of lithium iron phosphate pouch cells in liquid-cooled/heated self-contained modules for optimum battery management and safety.
The parallel hybrid design means that the XJ_e can run on gasoline power, electric power, or a combination of the two, optimized by the car’s energy management system, which selects the most efficient mode.
With a maximum system output of 334 PS (329 hp, 246 kW), the XJ_e is capable of 0—10 0km/h (62mph) in under 6.5 seconds and a limited top speed of 250 km/h (150 mph). With an all-electric range of 40 km (25 miles), fuel consumption is 3.2 L/100km (73.5 mpg US ) and CO2 emissions are less than 75 g/km.
The XJ_e investigates how a 5.0-liter V8 engine could be replaced by an advanced 2.0-liter hybrid powertrain to deliver similar performance and refinement, but with CO2 emissions of less than 75g/km. While the XJ_e is an experimental project, it highlights that JLR customers can expect some exciting low-carbon products in the future.—Bob Joyce, Engineering Director, JLR
Part funded by the UK 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.
Evolution of REEV Technologies—Building a UK Supply Base’ (REEVolution) is a Collaborative R&D project funded by the Technology Strategy Board that is creating new high performance Range Extended Electric Vehicles (REEV) and Plug-in Hybrids Electric Vehicles (PHEV).
Jaguar Land Rover (JLR) leads a consortium comprising Axeon Technologies Ltd, EVO Electric Ltd and Xtrac Limited; and three vehicle manufacturers: JLR, Lotus and Nissan Motor Company Ltd. for INFINITI brand.
Three new demonstrator vehicles are showcasing new technologies: the Jaguar XJ_e, the INFINITI EMERG-E and the Lotus Evora 414E, all on static display in their respective stands at Goodwood.
