In the new acoustic test benches in the new FIZ Project House North, which are specially designed to meet the requirements of electromobility, all driving situations can be realistically mapped. Disturbing noises, which the trained ears of the development engineers notice during test drives on the road, can be recreated there and eliminated in a targeted manner. Roller dynamometers with a unique quiet level and exchangeable coverings enable the measurement and validation of drive acoustics and tire noise on all road surfaces relevant to everyday traffic around the world. The requirement for the BMW i7 is to redefine the high standards of the luxury segment in terms of acoustic comfort as well. In particular, great importance was attached to the silent power generation of the electric drive. The acoustic optimization of the electric drive units, the model-specific bearing concept and a newly developed noise encapsulation for the electric motors all contribute to this. The sum of these measures helps the BMW i7 to achieve effective sound decoupling across a wide frequency range, which ensures maximum acoustic comfort in the interior in all driving situations. As a result, the driver of the purely electric luxury sedan always has the choice of enjoying either the characteristic silence of the drive or the emotionally powerful BMW IconicSounds Electric from the cooperation with Hans Zimmer
