- BMW says the EV M3’s sound must help drivers judge speed, not just add drama.
- It won’t copy a V8, V10 or straight-six, but BMW studied them to understand emotion.
- Real e-motor sounds are used as a base, then enriched to avoid a flat EV drone.
BMW admits fast electric vehicles have one major problem. Sure, they have brutal acceleration, but without the acoustic feedback drivers are used to, it can be hard to judge speed around a track. That’s a problem it's trying to solve with its upcoming electric M3.
