This is the prototype Felber Autoroller

[Wendax]

Yes, locked for you to find its name. (It can even be seen on the picture.)

Funnily enough, I found an article on the net which states that this prototype was the evolution of a previous prototype nicknamed "Murli" and I also found that the production vehicle was nicknamed "Laubfrosch" or tree frog. I didn't realise that this also had a name, but the nose badge appears to say Wr Leicht-Baby or Light Baby

[Wendax]

Yes, I didn't notice its name "Wr. Leicht-Baby" (= Wiener Leicht-Baby = Light Baby from Vienna) either before I saw a high-resolution picture of the car today. Otherwise I would have edited the puzzle picture. 

One more point for you.

Thanks for clarifying, I did wonder what that Wr prefix indicated.
