Jaguar Land Rover showcases MHEV, PHEV and BEV Concept_e demonstrators; electric Drive Module

At the CENEX Low Carbon Vehicle event in the UK, Jaguar Land Rover (JLR) is showcasing three Concept_e research demonstrators—a mild hybrid, plug-in hybrid, and battery-electric vehicle—including a new novel high performance, modular electric drive module (eDM) developed in-house by Jaguar Land Rover.

These are capable of producing twice the power and torque of any electric motor-generator currently in production, JLR said, and can be inserted between any engine and transmission to create MHEV or PHEV, or used alone for a BEV.

The Concept_e technologies are the output of an advanced powertrain research program for state-of-the-art, next-generation hybrid and battery-electric powertrain technologies which began in 2013.

Led by Jaguar Land Rover, this two-year £16-million (US$25-million) research project is part-funded by the UK’s innovation agency, Innovate UK and involves 12 UK technology partners. (Earlier post.)

The three Concept_e research demonstrators include:

Concept_e MHEV research
Concept_e MHEV. The Mild Hybrid is based on a Range Rover Evoque donor vehicle and features a prototype diesel engine (90 PS) and a 48V electrical system. It incorporates a 15 kW crank-integrated motor with disconnect clutch within a hybrid module sandwiched between the engine and 9 speed transmission. The motor-generator is powered by an advanced 48-volt electrical system and 48-volt lithium ion battery pack. Click to enlarge.

Concept_e MHEV research
Concept_e PHEV. The Plug-In Hybrid employs a similar architecture to the MHEV but with a prototype gasoline engine (300 PS) and 8-speed transmission longitudinally mounted within a Range Rover Sport donor vehicle. The electric motor is capable of up to 150 kW and also takes up the function of the starter motor. The motor draws electrical energy from a 320-volt lithium ion battery packaged in the boot. The hybrid powerplant drives through the conventional automatic gearbox normally fitted to the Range Rover Sport and the full time four-wheel drive system is retained. Click to enlarge.

Concept_e MHEV research
Concept_e BEV. Concept_e BEV is a bespoke research demonstrator based on Jaguar Land Rover’s aluminium vehicle architecture. The underbody has been modified to mount the 70 kWh high voltage lithium-ion traction battery and electric axle drive (EAD) units. The front drive unit features a single speed transmission coupled with an 85 kW electric motor. The rear drive unit features a twin speed transmission coupled with a 145 kW electric motor.

The Concept_e partners include Zytek Automotive, GKN Driveline, Motor Design Limited, AVL, Drive System Design, Williams Advanced Engineering, Delta Motorsport, Tata Steel, Bristol University, Cranfield University and Newcastle University.



Batteries in the right place (à la TESLA)?

Producing twice the power and torque than other electric power trains? This seems to be exceptional?

Will TESLA (and many others) copy this straight looking more powerful approach?

Stick to the facts. Tesla's Model S P90D has 650,000 watt 750hp motors. This Jaguar concept has a combined 230,000 watt motors and a small 70 kwh battery for a large Land Rover it will not have 200 miles range.



Isn't the TESLA S-90D overpowered by at least 50% or more. Something like 230 KW may be more than enough in more efficient vehicles with higher efficiency power trains, very high efficiency heat pumps, accessories, tires, less drag design etc.

Half size batteries would cost and weight a lot less giving more range at a much lower cost? It would be a win-win solution?

Future EVs (even TESLAs) will have to be down sized (TESLA III and many others???) and progressively improved to achieve extended range at an affordable price and to compete with improved lighter ICEVs.


Right sizing is more practical for the average consumer.

The average consumer cannot afford a long range BEV and that is not going to change until we get self-driving cars that will not be owned by the average consumer but hired on a trip by trip basis using a Smartphone. Small one person self driving BEVs will be everywhere in the cities and the suburbs so you only need to wait a few seconds before one arrive after you order the trip. We will see such services emerge between 2020 to 2025 and it will become the world fastest growing industry until they take over most other forms of transportation. Until then BEVs that sells will all be luxury high power and long-range and expensive. You need high power to compete in price with luxury gassers that have much higher cost per hp than EVs and more so the more hp. Tesla's 750 hp Model S is much cheaper than the one million USD supercars that it outperforms.

Harvey I was pointing out your error in saying that Tesla was less powerful than this Jaguar concept which it is obviously not. And straight looking means less aerodynamics and lees range. You should know that.



You make some bold predictions.

True, they are bold and I did not think like this a year ago. But after giving it a lot of thought and reading through thousands of news pages on the topic and doing my own calculation this is the picture that I see very clearly. There will be many other types of self-driving cars than those one-seaters with space for luggage (such as groceries) but they will not be as common as the one-seaters and they will therefore take longer time to hire and they will also cost more to hire. At the other end of the scale you could hire a self-driving auto camper with toilet bed and a small kitchen. Use that for long-range all night transportation while you sleep instead of an airplane to a city 500 miles away.

I can even be more specific about my predictions. The self-driving one seater will cost you less than 15 cents per mile to drive and be hugely profitable for the company that operates them. A Toyota Camry self-owed and self-driven will cost you about 40 cents per mile (everything included) and a old taxi with a cap driver will cost you 1.4 USD per mile.
