[Video] 2018 BMW M5 F90 Interior Plus Start-up Sound and Acceleration

Thanks to a new F90 BMW M5 prototype that spotted last week near the Nurburgring, we now get a closer look at what the interior looks like. The video below also lets us hear the start-up sound and the exhaust sound. The most important revelation in this video is that the new 8-speed automatic transmission shifter actually looks very similar to the one seen in the Concept 8 Series. Some other interior details were revealed including a red push start button, exhaust flap button, M1 and M2 buttons, and carbon fiber trim.

The reveal is expected to happen in a few months, followed by a public introduction at the 2017 Frankfurt Auto Show.
