According to BMW, the design of wheels and their aerodynamics have an impact on the overall kinetic energy efficiency of vehicles as high as 30%. This is why BMW wants to launch its own aerodynamic wheels for electric vehicles. It will first be deployed on BMW's first SAV electric vehicle iX3, which is basically made of light aluminum, with multi-piece aerodynamic design and embedded blades. According to BMW, compared with the X3 with general traditional power, its weight has been reduced by 5%. Due to the new aerodynamic design of the hub and the optimization of the airflow effect around the wheel arc, this aerodynamic hub is lighter than the BMW model equipped with aerodynamic wheels before 15%.
BMW iX3 is optimized in aerodynamics and weight, so press? According to the European WLTP test standard, its overall power consumption can be further reduced by 2%, equivalent to 0.4? KWh/ 100km, which will further extend the cruising range of the vehicle 10 km. The appearance of the wheel can provide many different forms and changes, which makes it more widely used in iNext and i4. ? Aerodynamic wheels on BMW iX3 combine light structure and reduce air resistance, and there are newly designed V-shaped aluminum spokes. The new wheel hub base uses less material than before, and then it is made of lightweight guide blades with precision molds and integrated between spokes on the outer wheel hub, which can reduce the generation of air vortex in the wheel arch.
The metal substrate of aerodynamic wheel hub can also be painted in different colors, and the owner can also choose to grind or polish the surface. All versions of the bottom wheel can be equipped with blades, and its appearance can also be selected according to the owner's preference, and even the embedded blades can be painted first.
