Plastic applications offer a particular advantage when it comes to extending the range of hybrid and electric cars, but also improving driving dynamics.
Both individual design elements and so-called full covers are used for this purpose. They optimize airflow around the wheel, reducing drag. These applications are typically much larger than simple design elements and allow drag to be optimized without adding too much weight to the wheel compared to an equivalent solid cast wheel. This is particularly important for e-vehicles, as it can increase the range. Weight reduction not only improves ride comfort but also enhances driving dynamics. In the sports car sector, aerodynamic trims are also used to control the flow of air around the overall vehicle. This is achieved through the high design flexibility of the plastic.
For even more design possibilities, the surface of aero versions can be matte, textured or even high gloss polished.
