A strange Beamng car I found a long time ago

Hello !

So, A long time ago, Beamng realease 2 update in a very short time, one probably for correct bug,
But when before the second update comming out, I found a very WIP car in the list, which I can use just one time, after the car has totaly gone and I couldn't find it in the car list :


I think It's the 200Bx, but i'm not sure, what car you think it was ?

(At the at the time I don't post thing on the Forum so ...) Wololo
