In order for electric vehicles to have a greater cruising range, in addition to equipped with an efficient power system, including a larger battery capacity, all components of the vehicle must also strive to pursue high efficiency. Tire manufacturers develop exclusive low-wear tires for electric vehicles. , designers have made the car shape have lower wind resistance, and in addition to lightweighting the wheels, some car companies have also developed low-wind resistance wheels with excellent aerodynamics. BMW's first electric SUV, iX3, is expected to go on sale in the middle of this year. BMW has released relevant information about the car. This week, it also revealed that the car is equipped with a weapon that will greatly help with mileage: Aerodynamics Wheels.
According to BMW, on today’s cars, the wheels and their aerodynamic design have an impact of up to 30% on the overall kinetic energy efficiency of the vehicle. This is why BMW is launching an aerodynamic wheel hub exclusive to electric vehicles. It will be first deployed on BMW's first SAV electric vehicle iX3. It is basically made of lightweight aluminum and combined with a multi-piece embedded blade aerodynamic design. According to BMW, compared with the conventionally powered X3, its weight is reduced by 5%. The wheel hub has a new aerodynamic design, coupled with the optimization of the airflow effect around the wheel arc, this aerodynamic wheel hub is more durable than previous BMW models equipped with aerodynamic wheel hubs. 15 lighter.
The BMW iX3 has been optimized in terms of aerodynamics and weight. Therefore, according to the European WLTP test standard, its overall power consumption can be reduced by another 2%, equivalent to 0.4kWh/100km, and thus This will extend the vehicle's cruising range by another 10 kilometers. The appearance of the wheel can be provided in many different forms and variations, making it more widely applicable to iNext and i4. The aerodynamic wheels on the BMW iX3 incorporate lightweight structures and reduce air resistance, as well as newly designed V-shaped aluminum spokes. The new wheel hub base uses less material than the previous one, and uses lightweight guide blades. Manufactured from precision molds and integrated between the outer spokes of the wheel hub, they reduce the generation of air vortices in the wheel arches. The metal base of the aerodynamic wheels can also be painted in different colors, and owners can also choose a matte or polished finish. All versions of the bottom wheel can be equipped with blades, and their appearance can also be customized according to the owner's preference, with a specific gloss, polish and pattern. Even the embedded blades can be painted in a preferred way.
