As of now, only a handful of models from Jaguar Land Rover are hybrids and that’s going to change soon with more future models planned both in PHEV and mild hybrid applications.
The latest report from Gaydon suggests that the Range Rover Sport is the top candidate for plug-in hybrid system, while the smaller Evoque and Discovery Sport models are to benefit from a mild hybrid set-up.
There are plans to downsize the Range Rover powertrain and shoehorn an Ingenium four pot with a plug-in hybrid module capable of touching 295bhp or more.
Last year, JLR invited a few journalists for an engineering presentation where it announced that it was building its own hybrid electric motor as aftermarket modules were not that suited. This means that the new Electric Drive Module (EDM) had to fit into the structure of the existing Range Rover and pair up with an eight-speed ZF automatic gearbox. For ensuring low centre of gravity, the battery pack is packaged under the boot floor and is expected to be juicy enough to allow for a 30-40km electric only driving range. At the time of writing, JLR’s ultra compact EDM measuring just 162mm long offers 201bhp and 332lb ft of torque. This could increase later on.
JLR’s mild hybrid project is looking at boosting and balancing a prototype three-cylinder Ingenium diesel engine equipped with an electrically powered turbocharger using a dedicated EDM. The mild hybrid application will require modest 20bhp and will work in tandem with 48V DC electrical system that powers the water pump and air-conditioning.
Since three-cylinder engines are not known to be smooth runners, JLR engineers claim that they have found a solution to the imbalance issue by using both a dual-mass flywheel and a pendulum absorber.
It’s expected that the new hybrid systems will also be used in future versions of the Jaguar F-Pace as well as the XF and future XJ models. And in comparative terms, the output figures from the EDMs so far are quite favourable. JLR expects to introduce the hybrid SUVs early next year.
