Jaguar is to offer all existing I-Pace owners a free update designed to extend their car’s range.
The firm has used insights gained from the Jaguar I-Pace eTrophy race series to develop system updates that improve the performance of its first all-electric SUV.
It says that the optimisation of battery management, thermal systems and all-wheel drive system should give drivers up to 12 extra miles on a single charge.
The I-Pace was launched last year with an official WLTP range of 292 miles. Jaguar says that the free software updates will not affect the official figures but should add around eight per cent to the real-world range achievable from the 90kWh battery.
Shortly after the road car’s launch, Jaguar began the eTrophy single-make racing series and has used the data gathered from that to make software changes to several key elements of the car’s drivetrain.
Stephen Boulter, vehicle engineering manager for I-Pace, said: “The Jaguar I-Pace eTrophy has generated a huge amount of data for us to analyse and those marginal gains, derived from competition on the track, are now being applied to customers’ cars to further enhance their driving experience. The new software updates optimise the powertrain control systems to improve efficiency and allow I-PACE drivers to travel even further on a single charge without any hardware changes – it really is a case of the vehicle getting better with age.”
What are the changes?
The changes derived from the eTROPHY race series include changes to the torque distribution between the front and rear motors, intended to deliver greater efficiency when drivers are using “eco” mode. Jaguar says that the system will still deliver permanent AWD traction. Refinements have also been made to the thermal management control system to make greater use of the active radiator vane system, closing the vanes more frequently to enhance aerodynamic performance more of the time. The updates will also allow the battery to run to a lower state of charge than previously without, Jaguar says, affecting driveability, durability or performance.
Jaguar says its engineers have also analysed more than 50 million miles of real-world driving data from I-Pace owners around the world.
Using this information, the update includes changes to the regenerative braking which will help the car’s brakes harvest energy more efficiently when the battery is in a high state of charge. It will also bring changes to the predictive range calculation to be more accurate and consistent as well as being more reflective of individuals’ driving styles, and enhance the over-the-air software update abilities.
I-Pace owners can arrange to have the updates applied to their car free of charge at their nearest Jaguar dealer now.
