- BMW iX3 Neue Klasse prototype exceeded 800 km on a single charge in real-world driving conditions.
- Advanced energy recuperation and thermal management helped maintain efficiency across challenging terrain.
BMW has reported a significant milestone for its upcoming BMW iX3 Neue Klasse long wheelbase model after completing a demanding real-world endurance drive in China. On June 10, the company announced that the iX3 50L xDrive prototype successfully covered more than 800 km on a single battery charge while driving around Qinghai Lake. The vehicle completed the full route, starting and finishing in Xining, with approximately 2% battery capacity remaining, highlighting the efficiency potential of the Neue Klasse electric vehicle architecture.
The prototype recorded an energy consumption figure of only 12.6 kWh per 100 km throughout the journey. Based on the measured consumption and remaining battery reserve, the test indicated a potential driving range of approximately 835–840 km under the conditions experienced during the route. The result demonstrates the effectiveness of the vehicle's electric powertrain, battery system, and overall energy optimization strategy during extended operation on public roads.
The route was designed to reflect practical everyday driving rather than controlled laboratory testing. The vehicle traveled on normal public roads amid regular traffic conditions, providing a realistic assessment of its performance. Starting at an altitude of roughly 2,200 meters above sea level, the journey climbed to nearly 4,000 meters before returning to the starting point. The route involved a cumulative elevation change of close to 2,000 meters, creating continuous uphill and downhill sections that placed additional demands on vehicle efficiency and thermal management.
The challenging terrain provided an opportunity to evaluate how the electric SUV manages energy usage under varying loads. Continuous ascents required sustained power delivery, while descents enabled the vehicle to recover energy through regenerative systems. These conditions tested the effectiveness of battery management, cooling performance, and overall drivetrain efficiency across a wide range of operating scenarios encountered during the trip.
The vehicle also faced a variety of weather conditions during the endurance drive. Snowfall, heavy rain, and strong sunlight at high altitude were encountered throughout different stages of the journey. Ambient temperatures fluctuated between 1°C and 21°C, creating additional challenges for battery performance and passenger comfort. According to the company, the vehicle's thermal management system maintained appropriate operating temperatures for both the battery pack and cabin, supporting consistent performance despite changing environmental conditions.
One of the key technologies highlighted during the test was BMW's Heart of Joy system, which works in conjunction with energy recuperation functions to improve efficiency. During many everyday driving situations, particularly on downhill sections, the vehicle can decelerate using regenerative energy recovery rather than relying primarily on conventional braking. This process helps convert kinetic energy back into electrical energy, which is returned to the battery and contributes to extending driving range while reducing overall energy consumption.
