Shame that the engineers at PMD did not keep this overall design for the flanks for the GP.....
Everything above the beltline is the same as what went into production but all below that was tossed.
This prototype is more in tune with the sides of the other 3 cars of the 1st gen platform, the sides are smoother, do not fold in at the bottom, more complete coverage all of the wheels, body does not taper in at the front and rear.
That's a really good looking car, too bad it wasn't kept as it sits.
