I think I can explain that one...I was in manual shift mode and I hit the rev-limiter before I expected and didn't shift for what felt like 3 seconds . You can see the speed in MPH is stuck at 65 on those cells. I know on other cars, they retard timing and pull fuel once the limiter is reached, so I'm assuming the same for the Mercedes based on the data we see. I'll let some others chime in to see what the consensus is
