Listen to the crazy sound of Tesla Semi electric truck prototype accelerating

That’s going to turn heads everywhere if it stays sounding like that. Sort of like a turbo charged sports car take off.

Sounds like an variable frequency drive in combination with tire noise. Youtube has some good videos on how VFDs sound like.

Are there any detailed specs on how Tesla controls the electric motor(s) in the truck? AC, DC, controller types,etc..?

Is it me or it's a pretty standard sound of a pretty mundane electric train engine vagon accelerating?
