The new BMW aeroacoustics and E-engine center

The new Aeroacoustics and Electric Drive Center (AEC) starts operations at the BMW Group's Research and Innovation Center (FIZ).

After almost forty years, the old aeroacoustic wind tunnel is being replaced by BMW.

The building consists of two halves: In addition to a multifunctional part with workshop, testing and measurement equipment and a prototype for high-voltage batteries and inverters, the AEC has a technically and structurally unique wind tunnel.

With a length of just under 100 m, a height of 45 m and a width of 25 m, it is the world's largest vertical acoustic wind tunnel and at the same time the quietest.
