two extra wheels ???????????????? on the front

does anybody know if it would be viable to fit two extra wheels to the front of the vectrix like the one thats coming out and what cost would it be panels and extra running gear ?

and what price are we looking at to get the range of approx 90 miles range top speed aprox 50+ and how many would i need ????
