Euro NCAP carried out "sine-with-dwell" tests according to the ESC GTR global technical regulation, which is based on the US regulation FMVSS126. For cars that allowed the ESC system to be switched off, tests were carried out with ESC ON and OFF. Cars were tested by undergoing multiple runs, sometimes as much as 60 per car, each time increasing the steering angle and input. The clip shows the 'first ESC off test' where the car span out. The 'ESC on test' is the one with the same steering input.
