To ensure the brand’s first electric vehicle (EV) can withstand anything customers throw at it, JLR is putting Range Rover Electric prototypes through rigorous testing in harsh environments.

JLR released information about that tests on Tuesday. In the vicinity of the Arctic Circle, where temperatures can dip as low as -40 degrees, there are extreme cold conditions for testing. This is to guarantee that in these extremely low temperatures, the electric powertrain nevertheless achieves performance goals.

The testing conducted in cold weather also enable engineers to assess the vehicle’s performance on low-grip surfaces. Tested on frozen lakes with very repeatable circumstances, the prototypes allow the engineers to optimize numerous chassis systems, such as a new traction control system made specifically for the vehicle’s electric drivetrain.

For managing wheel slide, the Range Rover Electric uses the control module for the electric motors (the number of which JLR has not disclosed) rather than the ABS-linked traction control system found in its gas-powered lineup. As per JLR, this causes the system’s reaction time to decrease from approximately 100 milliseconds to almost instantaneous.

Testing in West Asian deserts, where temperatures can rise above 120 degrees, is another way to address extreme heat, which can significantly impair the performance of EVs.

Modified versions of the MLA (Modular Longitudinal Architecture) chassis, which powers the gas-powered Range Rover, are utilized by the Range Rover Electric. Because the electric version of the platform has an 800-volt electrical architecture, it can be charged very quickly using a DC fast charger. There will also be support for apps made to help optimize range and over-the-air updates.

The prototypes demonstrate how little will be visible on the outside to distinguish the two versions.

The Range Rover Electric is expected to make its premiere later this year, and reservations are already being accepted. JLR will soon release more electric vehicles. In addition to an electric Range Rover Velar, the first of a new series of electric Jaguars is scheduled to debut in 2025.
