New 2025 BMW X3 Prototype Testing Has Started
58The final stages of development for the new BMW X3 are taking place at the BMW Group's test center in Miramas, located in the southern part of France. Here, engineers are meticulously adjusting the chassis control systems and the driver assistance technologies of the vehicle. This fourth generation model of the Sports Activity Vehicle, which occupies a prominent position in the premium mid-range category, will soon be launched. It will feature both advanced combustion engines and a sophisticated plug-in hybrid system.
Throughout its development, the BMW X3 has been rigorously tested under a variety of challenging conditions, including snow, ice, and extreme heat, as well as on rough off-road terrains, ensuring its readiness for mass production. The vehicle's practicality and performance have been scrutinized in heavy urban traffic, on serpentine rural roads, bustling highways, and even on specialized race tracks.
The test site in Miramas offers a diverse array of road simulations, including an asphalt oval, a highway ring, and various slalom, serpentine, and circular tracks, in addition to off-road paths and handling circuits with varying surface types. These facilities are crucial for refining the vehicle's acceleration, suspension, damping, steering precision, and braking capabilities.
In terms of driving dynamics and efficiency, the new BMW X3 is improved by its intelligent use of lightweight materials and aerodynamic enhancements, boasting a drag coefficient of 0.27—a benchmark in its class. The vehicle also features a broader wheelbase and reduced lift at the rear axle compared to its predecessor. Enhancements in body rigidity and chassis integration contribute to the car's improved stability. Changes to the axles' kinematics and elastokinematics, a 19 percent increase in front wheel caster, and a more responsive steering ratio, together with revamped anti-roll bars, significantly enhance the vehicle's directional stability and cornering prowess while maintaining comfort.
Optionally available is an Adaptive Chassis with electronically controlled shock absorbers, allowing for adjustment between two settings via the My Modes function during the dynamic testing phase in Miramas. Standard in this new model is the latest BMW Lateral Dynamics Management, which precisely controls steering torques, wheel slip, and yaw torque distribution tailored to various driving conditions.
BMW's expert engineering ensures that each component of the drive and chassis technology is in perfect harmony, delivering a blend of precision, control, and adaptability that defines the BMW SAV driving experience.
Additionally, the new BMW X3 is equipped with the most recent BMW iDrive system, based on the BMW Operating System 9. This includes the BMW iDrive Controller and an enhanced suite of automated driving and parking systems, surpassing the offerings of its predecessor and exceeding the safety standards of the Euro NCAP tests. The vehicle's assistance systems, known for their precise braking and steering interventions, facilitate a seamless interaction between the vehicle and its driver.
The technological prowess of the BMW X3 is complemented by state-of-the-art sensors, software, processors, and network capabilities. Noteworthy features include the Active Lane Change Assistant and the Parking and Maneuver Assistant, which enables drivers to execute parking maneuvers remotely using a smartphone.
