That’s why we are so proud that the all-electric BMW i4, the M version of the i4 and the BMW iX will offer the IconicSounds Electric driving sound, created in cooperation with Academy Award winning composer Hans Zimmer.

I absolutely love how it sounds at 1:30!

You know BMW isn't messing around when they get Hans Zimmer on this project. I really like the sound, it's kind of like a tuned down version of the Taycan's sound.

Also, I really want to know what this car is that was in the video!
