Note that there isn't really any proof of the lap yet and it doesn't have the usual GM level of documentation. This is either fake or GM just doesn't have the story ready for release yet. Time will tell . . .

incredible!

130 turns +- and using more revs = a few 1/10's per corner.... just an assumption. Magnussen is an incredible driver.
