In the picturesque landscapes of Miramas, southern France, the new BMW X3 is nearing the completion of its development cycle. At the BMW Group test center, the fourth generation of the Sports Activity Vehicle (SAV) undergoes meticulous final adjustments to its chassis control and driver assistance systems. Poised to debut in the premium mid-range segment, this model showcases cutting-edge hybrid and efficient combustion engines. The comprehensive tuning program ensures that each variant, regardless of its configuration, achieves exceptional handling and performance.
Key Highlights of BMW X3’s Testing:
- Extensive tests across varied conditions, including snow, ice, and extreme heat.
- Enhanced everyday usability and comfort tested in urban and rural settings.
- Optimization of aerodynamics and lightweight construction leading to a drag coefficient (Cd) of 0.27.
- Improved handling and stability features, such as a more direct steering ratio and advanced anti-roll bars.
- Introduction of an Adaptive Chassis with selectable shock absorber settings for tailored driving dynamics.
The SAV’s journey to refinement has covered a multitude of tests— from chilling Arctic conditions to scorching desert trials, and rugged off-road challenges. Its adaptability is further proven on bustling city streets, serene country roads, and high-speed highways. These varied tests ensure the BMW X3 is prepared for any driving scenario, providing a reliable and dynamic performance typical of BMW’s prestigious engineering standards.
Detailed Development and Enhanced Performance
Engineers at Miramas leverage a variety of test tracks to fine-tune the BMW X3’s driving characteristics. The vehicle’s dynamic properties, such as acceleration, suspension responsiveness, and braking efficiency, are scrutinized and enhanced for optimal performance. Significant advancements include a wider track, reduced rear axle lift, and a 19 percent increase in front wheel caster for improved directional stability. The vehicle also benefits from a more direct steering ratio and finely-tuned anti-roll bars, enhancing both maneuverability and comfort.
The option of an Adaptive Chassis with electronically controlled shock absorbers illustrates BMW’s commitment to customizable driving experiences, allowing drivers to select settings that best suit their driving style.
Integration and Innovation in Automated Driving
The new BMW X3 features advancements in automated driving, supported by the latest BMW iDrive technology based on BMW Operating System 9. It includes an array of new automated driving and parking systems, such as the Active Lane Change Assistant and the Parking and Manoeuvre Assistant. These systems enable smoother and more intuitive interactions between the vehicle and driver, significantly surpassing previous models and competitors in terms of integration and functionality.
With state-of-the-art sensor technology and software advancements, the new BMW X3 not only meets but exceeds Euro NCAP safety standards, emphasizing BMW’s leadership in vehicle safety and performance integration. This comprehensive development approach ensures that the BMW X3 remains a benchmark for excellence in the premium SAV category.
