Tata Motors’ Jaguar is using technical knowledge gained from the I-Pace eTrophy race series to give current owners a range-boosting software upgrade which will also add enhanced Software-Over-The-Air functionality.

Dealers will carry out the upgrade.

The update optimises the management of battery, thermal and AWD systems to enhance the efficiency of the all electric powertrain.

The race series puts the EV SUV through extreme use conditions and the first competitive season yielded critical learnings for the durability and thermal control of the battery and torque management systems.

Engineers have also analysed data from 50m miles of real world journeys from all corners of the world.

Stephen Boulter, I-Pace vehicle engineering manager, said: “The 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 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.”

The all-wheel drive vehicle has a range of up to 292 miles from a single charge of its 90kWh Lithium-ion battery (WLTP cycle). While the new software upgrade doesn’t change the official certified range figure, the marginal gains developed from eTrophy analysis will give customers access to an improvement of up to 8% dependent on usage – equating to a potential extra 12 miles of real world range.

The changes include:

  • All-Wheel Drive: Changes to the torque distribution between the front and rear motors will deliver greater efficiency when driving in ECO mode – the system still delivers permanent AWD traction
  • Temperature control: Refinements to thermal management control will make greater use of the active radiator vane system, closing the vanes more frequently to enhance aerodynamic performance more of the time
  • Battery Capacity: Updates allow the battery to run to a lower state of charge than previously without affecting driveability, durability or performance

Additional changes derived from real-world data analysis include:

  • Regenerative Braking: The vehicle’s brakes will harvest energy more efficiently when the battery is in a high state of charge and the amount of energy recovery has been increased at lower driving speeds to maximise efficiency and range
  • Range calculation: Changes to the predictive range calculation algorithm will deliver a more accurate and consistent estimate of vehicle range, while being more reflective of an individual’s driving style

Customers are being invited to take vehicles to dealers to receive the complimentary update. The wide ranging changes will also enable enhanced Software-Over-The-Air (SOTA) functionality. After receiving the latest software, more electronic modules will be able to receive remote updates.
