The Black Series GT is probably one of the fastest roadcars of all time, on real tracks.

730hp, active aero, 6.43,616 minutes for the Nordschleife, which was the record for roadcars in 2020.

This is more than a minute(!) faster than the Mach 1 in 2021 (pos. 179), not to speak of my normal 2017 which needed more than 8 minutes.
