During 2021 and 2019 we visited the TT Circuit of Assen a couple of times for Supercar Madness and Japfest. There we saw a lot of supercars and sportscars arriving and leaving the event. Many participants were also revving their cars. In this video you can listen to some awesome cars like a 1250HP Supra Mk4, 700HP Armytrix GT-R with pops & bangs, Ferrari LaFerrari, Novitec N-Largo S F12, Aventador SVJ and many more!
