Last Sunday we visited the TT Circuit of Assen where Supercar Madness was being organized by 402 Automotive. It was a huge event with a lot of supercars and hypercars like a Pagani Huayra, Koenigsegg Agera R, Senna, LaFerrari, Huracan STO, Ford GT and many more! Unfortunately some of these cars arrived and left in a trailer. In this video you can see some of the participating cars arriving the event with a great acceleration and some powerslides!
