2020 Mercedes-Benz EQC 400 - The EQC is also very, very quiet, much quieter than the Jaguar I-PACE and it seemed just as quiet as the Audi. You don’t really hear the electric motors at work, just wind and tire noise and that’s all. When I asked Bastian Schult what was done to make the EQC so quiet and smooth, he replied that they elected to link the front electric motor on rubber mounts to a sub-frame, which is also rubber-mounted to the chassis. This double insulation, along with a cover placed on the rear electric motor, accounts for the quietness and the smoothness of the EQC.
