Jaguar Land Rover has re­vealed some of the new and in­no­va­tive low and zero emis­sion pow­er­train tech­nolo­gies it is re­search­ing at this year’s Cenex low car­bon ve­hi­cle event in the UK.

Three Con­cep­t_e re­search de­mon­stra­tors show­case this far-reach­ing fu­ture re­search, which in­cludes a new unique 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 in pro­duc­tion to­day. These 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 pro­gramme for state-of-the-art, next-gen­er­a­tion hy­brid and bat­tery-elec­tric pow­er­train tech­nolo­gies which be­gan in 2013.

Dr Wolf­gang Ep­ple, Di­rec­tor of Re­search and Tech­nol­ogy, Jaguar Land Rover, said: “This is a longterm Jaguar Land Rover re­search pro­ject ex­plor­ing all as­pects of fu­ture hy­brid and bat­tery elec­tric ve­hi­cle tech­nol­ogy. The three Con­cep­t_e ve­hi­cles will al­low us to test and de­velop ex­cit­ing new po­ten­tial tech­nolo­gies that could form part of our low and zero emis­sions vi­sion be­yond 2020.”

The three Con­cep­t_e re­search de­mon­stra­tors in­clude:

Con­cep­t_e MHEV. The Mild Hy­brid is based on a Range Rover Evoque donor ve­hi­cle and fea­tures a pro­to­type diesel en­gine (67kW and a 48V elec­tri­cal sys­tem. It in­cor­po­rates a 15kW crank in­te­grated mo­tor with dis­con­nect clutch within a hy­brid mod­ule sand­wiched be­tween the en­gine and nine-speed trans­mis­sion.

The mo­tor-gen­er­a­tor is pow­ered by an ad­vanced 48-volt elec­tri­cal sys­tem and 48V lithium ion bat­tery pack.

Con­cep­t_e PHEV. The PlugIn Hy­brid em­ploys a sim­i­lar ar­chi­tec­ture to the MHEV but with a pro­to­type petrol en­gine (224kW) and eight-speed trans­mis­sion lon­gi­tu­di­nally mounted within a Range Rover Sport donor ve­hi­cle.

The elec­tric mo­tor is ca­pa­ble of up to 150kW and also takes up the func­tion of the starter mo­tor. The mo­tor draws elec­tri­cal energy from a 320Vt 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.

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 HV 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.

Dr Ep­ple added: “En­vi­ron­men­tal In­no­va­tion is at the heart of our busi­ness. We have a wide-rang­ing low emis­sions tech­nol­ogy strat­egy, which has cre­ated in­no­va­tions like our In­ge­nium en­gine fam­ily and lighter ve­hi­cles. Tech­nolo­gies like these have al­ready helped us re­duce our fleet CO2 av­er­age by 25 per cent in re­cent years.

“Our fu­ture vi­sion is to con­tinue to re­duce emis­sions and im­prove fuel ef­fi­ciency while still de­liv­er­ing the lux­ury, per­for­mance, re­fine­ment and com­fort our cus­tomers ex­pect.

“Whether it’s op­ti­mis­ing the in­ter­nal com­bus­tion en­gine, ad­vanced hy­brid and bat­tery­elec­tric propul­sion sys­tems, the in­tro­duc­tion of new, light­weight ma­te­ri­als or the im­prove­ment of energy con­ser­va­tion through more ef­fi­cient heat­ing and ven­ti­la­tion tech­nolo­gies, we are leav­ing no stone un­turned to en­sure Jaguar and Land Rover ve­hi­cles emit sig­nif­i­cantly less emis­sions in the fu­ture.”
