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.
