Very easy. Go to Free Play and make sure to choose the Yas Marina Circuits and it's the North circuit you want to choose ( can be either day or night). Then choose either off the Koenigsegg cars and then go to "assists" and make sure ABS is
turned off.
after that when you come out of the hairpin just hold down the accelerator until you reach 200 MPH. Hopefully this helps! I have a video guide below for those who are stuck :)
