Interesting article. It looks like it is highly unlikely that you can over-rev a PDK, but may be possible in certain circumstances if really pushing it. Or maybe the parallel with the tiptronic gearbox they mention is not valid.
You can get pretty close.
At the PEC I really thrashed the Turbo and I deliberately pulled the down paddle to max out the revs, it went into the red and stayed there, the engine did not like it but I got no warnings.
Interesting for those who have sessions there booked to try it, in auto mode pulling the gears down when you should not to see what happens, then do it again but in full manual mode of the gear selector.
I hope you aren't suggesting that someone tries to break one of their cars!
Well I did honestly try, did a bit of off roading on some of the handling circuit bends when it ran wide and I kept the boot in.
Surprizing how late you can brake on the acceleration tracks if the car has ceramic brakes.
