The BMW iX3 Long Wheelbase successfully completed a demanding real-world endurance challenge covering more than 800 kilometers without recharging. A BMW iX3 50L xDrive prototype equipped with 21-inch aerodynamic wheels completed the Qinghai Lake grand loop, departing from Xining and returning to its starting point after more than 800 kilometers of driving on public roads.
The vehicle finished the route with 2% battery capacity remaining and achieved an average energy consumption of just 12.6 kWh per 100 kilometers. The result indicates a total range potential of 835 to 840 kilometers under the conditions of the challenge.
This achievement highlights the outstanding efficiency of the BMW iX3 Long Wheelbase under challenging real-world conditions, demonstrating BMW's approach to electric mobility: delivering confidence in every kilometer.
The challenge was designed to validate the efficiency potential of the BMW iX3 Long Wheelbase in an environment closely reflecting everyday customer use. Starting in Xining at approximately 2,200 meters above sea level, the vehicle climbed to nearly 4,000 meters before descending again and completing the loop back to its starting point.
Repeated climbs and descents across an altitude difference of almost 2,000 meters continuously challenged drivetrain efficiency, energy management and thermal control. Weather conditions added a further layer of complexity.
During the journey, the vehicle encountered heavy snowfall, intense rain and strong high-altitude sunshine, while ambient temperatures ranged from 1°C to 21°C. Combined with varying road surfaces, public-road traffic conditions and the demands of plateau driving, these conditions created a highly representative test environment for electric mobility in everyday use.
To reflect realistic customer driving behaviour, the entire route was completed in Efficient mode, balancing comfort and energy efficiency in a manner closely aligned with long-distance everyday driving.
The BMW Neue Klasse approach emphasizes system-level efficiency, measuring performance by how consistently a vehicle performs in real-world conditions across varying temperatures, elevations and road profiles.
