More than 800 Kilometers Without Recharging: BMW iX3 Long Wheelbase demonstrates Neue Klasse efficiency under demanding real-world conditions

More than 800 Kilometers Without Recharging: BMW iX3 Long Wheelbase demonstrates Neue Klasse efficiency under demanding real-world conditions.Qinghai, China. Demonstrating the efficiency potential of the BMW Neue Klasse, 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. The achievement highlights the outstanding efficiency of the BMW iX3 Long
Wheelbase under challenging real-world conditions and demonstrates BMW’s approach to electric
mobility: delivering confidence in every kilometer.
Real-world validation under demanding conditions.
Conducted entirely on public roads and under real-world traffic conditions, 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.
System-level efficiency: the Neue Klasse approach.
For BMW, efficiency is not defined by a laboratory figure. It is measured by how consistently a vehicle
performs in real-world conditions across varying temperatures, elevations and road profiles.
The challenge demonstrates how the technologies of the BMW Neue Klasse work together as an
integrated system to maximize efficiency under demanding real-world conditions.
Key contributors include:
• An optimized aerodynamic concept that minimizes energy losses at higher speeds.
• BMW’s in-house developed Energy Master, which intelligently manages energy distribution
based on route profile, temperature and driving conditions.

• BMW’s sixth-generation high-voltage battery featuring newly developed cylindrical cells and
108.7 kWh of usable energy, delivering significantly higher energy density while optimizing
packaging, weight and vehicle rigidity.
• A newly developed drivetrain combining an electrically excited synchronous motor and an
asynchronous motor, reducing energy losses by up to 40% while increasing overall drivetrain
efficiency by up to 20%.
• The Heart of Joy control system and highly efficient energy recuperation technology, enabling
energy recovery in up to 98% of everyday braking situations.
Thermal management plays an equally important role, particularly under demanding environmental
conditions. Cold mornings, warmer daytime temperatures and rapid transitions between rain and snow
require battery and cabin systems to respond efficiently and precisely. The integrated thermal
management system helps maintain stable operating conditions, supporting both occupant comfort
and consistent range performance.
Efficiency where it matters most.
The Heart of Joy control system works in conjunction with the highly efficient energy recuperation
system to maximize energy recovery. In up to 98% of everyday driving situations, braking can be
achieved through energy recuperation alone, allowing energy to be recovered during deceleration and
downhill driving. As a result, efficiency gains are realized precisely where customers experience them
most: in everyday driving. For BMW, efficiency is not only about achieving longer range. It is about
delivering predictable energy consumption, stable range performance and a reassuring driving
experience, even when conditions change significantly. Whether on long-distance journeys, mountain
roads or routes with highly variable weather conditions, customers benefit from greater confidence
behind the wheel. The challenge demonstrates that efficiency in the BMW Neue Klasse is not the result
of a single technology. It is the result of a holistic vehicle concept in which aerodynamics, drivetrain,
battery technology, thermal management, energy recuperation and intelligent control systems work
together seamlessly. As the first model of the BMW Neue Klasse, the BMW iX3 demonstrates the next
generation of electric mobility from BMW. By translating technological innovation into measurable realworld
performance, it delivers what matters most to customers: confidence in every kilometer.
