The GT Speedvision cup is pretty near production cars. So that is the biggest difference that I could see.
Also as the other guy said about aluminum foil around the outside of the car.
Also who knows what engine they are running.
Oh by the way...I rode in a ford mondeo with a bunch of mods at autoX...it cannot touch an M3.
One tried to race me on the highway...not even close.
