Not too big - the engine was derived from a standard Moskvich unit, so there should be no illusions - the car was made from what was available. 1995cc engine gave out 175hp. With about 890kg of weight it was capable of 200km/h, which should have been enough for rally tracks anyway. I think it raced in USSR actually, so it was not only a design study or anything like that. The car is still alive, by the way.

P.S. In Russian speaking sources the car is said to have been developed in 1988.
