What is this small car?

[Manwithnoname]

Hello everybody. First time posting on this site

For the past few days this car has been bugging me a lot and I can't figure out this at all.

It's from a 1974/75 documentary about the Soviet/Lithuanian rally driver Stasys Brundza. In one of the montages, this car was shown for a couple of seconds (participating in "Rallye Tour d'Europe" I presume?)

Source of the video (this car appears at 4:36): https://youtu.be/olDTESlEX9U

Any info about this would be very helpful!

The car has a very special rear end, but, unfortnately, it tells me nothing...

The movie is about Statys Brundza, so my best guess that it can be some kind of creation by VFTS. However, I very doubt that...

The number plate ПБ9053... It is either Perm Oblast or пробный = test/experimental??

Last question, where is the action? Most cars look to have Soviet number plates (even Alpine!?) so I cannot be sure if this is either Soviet Union event or "Tour D'Europe"..

Great mystery car! Maybe someone knows more?
