The car that we built has 2 big wheels connected by a rod in the back and then 1 big wheel on the front so it's sort of like a tricycle. Our car looks like a "derby" car because of the tail we put in the back. In the engineer process, we are ready to test our prototype.

I like the idea of the car looking a bit like a tricycle. My only question is how big is the tail of the car? Maybe it could throw the car off balance if it's too heavy.
