Jaguar XJ_e plug-in hybrid Review


Jaguar XJ_e hybrid electric plug-in

The Jaguar XJ_e plug-in hybrid engineering research vehicle, with fuel economy of 87mpg and emissions of less than 75g/km CO
, was on display at the Goodwood Festival of Speed.

Capable of 0-62mph in under 6.5 seconds and with a (limited) top speed of 150mph, the XJ_e achieves CO 2 emissions of less than 75g/km and a zero-emission range of 25 miles on electric power.

The XJ_e demonstrates how an advanced parallel plug-in hybrid design can deliver reductions in CO 2 emissions of over 70 percent, without compromising vehicle performance.

The innovative XJ_e project was created by JLR as part of its strategy to develop best-in-class low-carbon premium products, and follows other successful hybrid research demonstrators including the Limo Green and Range_e vehicles.

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.

Bob Joyce, Engineering Director, JLR, commented: “The XJ_e investigates how a 5.0-litre V8 engine could be replaced by an advanced 2.0-litre hybrid powertrain to deliver similar performance and refinement, but with CO 2 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.”

The XJ_e combines the class-leading lightweight aluminium vehicle structure from the Jaguar XJ with an advanced plug-in hybrid electric vehicle (PHEV) system, featuring the efficient 2.0-litre turbocharged direct-injection petrol engine which powers the Range Rover Evoque and a hybridised 8-speed automatic transmission.

The hybrid system uses a 69kW motor/generator and a 12.8kWh Lithium Ion battery pack, which can be fully charged by an external 240V domestic supply in around four hours. The battery pack can deliver an electric-only range of 25 miles.

The parallel hybrid design means that the XJ_e can run on petrol power, electric power, or a combination of the two, optimised by the car’s intelligent energy management system which selects the most efficient mode.

With a maximum system output of 334PS, the XJ_e is capable of fuel economy of 3.2l/100km (87mpg), meaning a maximum range of 1092 km (679 miles) on a full tank of fuel.


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, consisting of: 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 will showcase innovative new technologies – the Jaguar XJ_e, the INFINITI EMERG-E and the Lotus Evora 414E. The cars are ‘best in class’ and build on the skills of all of the businesses involved. The driving force behind this is to build a UK supply chain for new ultra low carbon vehicle technologies and position suppliers so that they can exploit the global market.
