The Vision GT is a concept racing version of the Chiron, I think? That aero device on the rear is massive, but I understand the size of it considering the speed the car can attain. It would be cool to see them race, but that W16 is no bueno....that thang is probably too heavy and thirsty to race. Kinda wonder if the Chiron will still be made considering the trouble VW is having and what probably lies ahead...
