Powerful plug-in petrol-electric system in addition to a three-pot diesel mild hybrid are from the pipeline
Developing plug-in hybrids alongside electric vehicles makes sense for JLR, because PHEVs will become relatively mainstream sooner than EVs. Their take-up will only be sped up by increasing traffic restrictions in cities such as London in addition to a crackdown on tailpipe pollution.
Although Land Rover has been selling a Range Rover V6 diesel hybrid since 2013, of which can be working on an all-completely new plug-in hybrid powertrain of which can be based around a completely new 295bhp four-cylinder Ingenium petrol engine.
According to an engineering presentation last year, the company decided to build its own hybrid electric motor. However, the completely new Electric Drive Module (EDM) had to fit into the structure of the existing Range Rover design line-up in addition to mate up with an eight-speed ZF automatic gearbox.
The battery pack can be packaged under the boot floor, although its capacity has not yet been confirmed. To be competitive, future JLR plug-in hybrids will need to have a real-world EV-only range of more than 20 miles in addition to probably nearer 30 miles.
Even though JLR engineers had to fit the completely new EDM into a space just 162mm long, of which still develops 201bhp in addition to 332lb ft of torque. These figures are significantly above the output of the 113bhp electric motor from the current BMW X5 xDrive40e, which would certainly be the hybrid Range Rover’s closest rival.
The BMW carries a claimed 0-62mph time of just 6.5sec, which leaves the way open for even more performance coming from the electrified Range Rover, which will most likely be launched late next year.
JLR’s second hybrid project can be classed as a mild hybrid electric vehicle (MHEV) in addition to can be based around the transverseengined platform used for the Evoque in addition to Discovery Sport.
This kind of ‘production-intent’ project can be technically more complex than the one for the Range Rover because of which uses both a completely new EDM in addition to a prototype three-cylinder Ingenium diesel engine equipped with an electrically powered turbocharger. This kind of prototype also carries a 48V electrical system of which powers the water pump in addition to air-con.
Using a three-cylinder diesel engine raises refinement problems, so the compact hybrid module (just 168mm deep) incorporates both a dual-mass flywheel in addition to a pendulum absorber to help smooth out the diesel motor’s inherent imbalance.
The EDM can be relatively modest, with an output of just 20bhp. However, its role can be to fill gaps from the torque curve in addition to help to boost the vehicle’s acceleration. Electric control of the water pump means of which of which’s easier to adjust the speed of the flow of coolant in addition to allow the engine block to heat up quicker. This kind of, in turn, gets the engine oil up to the correct temperature quicker, reducing friction in addition to improving fuel consumption.
Like the Audi Q7 e-tron plug-in hybrid, JLR’s MHEV powertrain will be able to shut down its engine in addition to coast downhill to preserve fuel. Any MHEV Discovery Sport or Evoque will probably not arrive before the end of 2018.
