These optimized chassis bushings are tuned to handle the increased vehicle weight and higher preloads found in BEVs, while also ensuring great NVH performance. This is critical to occupant comfort and ride quality. Furthermore, BEV powertrains are substantially quieter than the ones found in ICE-powered vehicles. This presents an important challenge, since sounds previously masked by the ICE like road noise, chassis excitations, and in-cabin noises, become far more noticeable. This essentially calls for solutions with better high frequency isolation characteristics.
The chassis mounts employ optimized rubber compounds with low-hardening characteristics to better address and mitigate the frequencies encountered. The improved design allows the solution to better handle dynamic load (while driving), as well as static preload (while stationary).
