The original design was best. The car has to be coming at the horse and the horse has to be jumping the car. Otherwise visually you're left with the sense that the horse is running the same direction as the car and it's going to land on the car when it jumps. The design has to incorporate the combined space of the front of the horse over the hood of the car or else you're going to have too large of a logo.

But I do like the more sketchy lines of the car matching the lines of the horse in the later figures.
