What non-modified street legal car goes the fastest in reverse?

The vehicles that govern how fast they can go in reverse likely aren’t getting mentioned in this thread in the first place.

We’re also talking about both current production, and cars from 20, 40, or even 60 years ago. Speed regulators are rather recent inventions on that time scale.

IIRC, NSU was mentioned upthread - a company that should later morph into Audi.

And those were somewhat famous for “technically” being able to drive in reverse as fast as in a forward gear …

I recall, my grandfather owning a NSU Prinz in the 70ies … a remarcable car where you had to somewhat concentrate on which direction the car was pointing as the side-view gave few clues …

ridiculously small by today’s standards …
