Range Rover Electric Completes Second Phase Of Arctic Testing

Range Rover confirmed the completion of a second winter testing season for its electric vehicle prototypes. Testing took place in Arjeplog, Sweden, covering around 45,000 miles on frozen lakes and land tracks. Engineers tested thermal systems, battery operation and all-terrain capabilities in low temperatures.

The ThermAssist system was tested to manage energy use and maintain battery and cabin temperatures. The system is designed to reduce heating energy use by up to 40 percent and operate at temperatures as low as -10°C. It also aims to preserve charging performance during cold weather.

The Range Rover Electric uses an 800V battery developed by JLR. The 117kWh battery consists of 344 prismatic cells in a two-layer structure. Testing focused on energy density, charging times and system operation in sub-zero conditions.

Engineers tested single pedal driving, allowing the vehicle to slow down and stop without using the brake pedal. This function is linked with Terrain Response and Hill Hold features. Switchable twin-chamber air suspension was tested to manage weight distribution and vehicle control on low-grip surfaces.

Thomas Müller, Executive Director, Product Engineering, JLR, said, "Rigorous testing procedures in extreme and unpredictable conditions like those experienced in Arjeplog are crucial to Range Rover Electric's real‑world reliability and resilience. Our second winter season in the Arctic Circle has provided the perfect opportunity for us to put our new ThermAssist technology to the test, and it has surpassed our expectations. It will help to ensure Range Rover Electric’s range remains intelligently optimised while also ensuring charging speeds are maintained when a top‑up is required."

The Intelligent Driveline Dynamics (IDD) system was tested for its ability to distribute torque between the rear wheels. Integrated Traction Management was evaluated for motor speed control and slip management, aiming to maintain stability across different surfaces.

Matt Becker, Vehicle Engineering Director, JLR, said, "In its driving character, Range Rover should seamlessly combine capability and refinement. Delivering both in an electric vehicle in a way that doesn’t diminish the vehicle in other areas is incredibly challenging. By increasing its torsional stiffness and improving its responses, we’ve been able to maintain a customary Range Rover driving experience that feels familiar. We have delivered on this promise by marrying all the essential Range Rover elements with new and advanced technologies."
