A new teaser shows the engineering team's progress on the chassis dynamics of the electric M3. We are transported to Sweden, where BMW has settled into a private test centre in Arjeplug, near the Arctic Circle. Near the end of the video, we find ourselves inside the M3's interior, watching a pair of engineers perform acceleration. It is here that we first hear the synthesised exhaust sounds of the electric M3 being broadcast through the speakers.
The sound can be described as an electric interpretation of the operation of a six-cylinder petrol engine. Which isn't really surprising, given BMW's long history with this engine layout. The video cuts off without letting us hear more, so it's possible that the sound could change as speeds increase. There's also the possibility of a simulated gear shift, such as in the Hyundai Ioniq 5 N. Last year, BMW's M division said it would build its electric cars with simulated gear shifts. And if you look closely, just before the video cuts off, the driver reaches for a petal on the steering wheel.
BMW has already released three such videos since December, so it's likely that the company will release a few more before the car officially debuts.
