There seems to have been some mutterings (on RTL) that Ferrari's use of qualification mode to get past Lewis was an illegal move. As much as I'd have liked Lewis to win Ferrari's use of this seems to have been a gamble that paid off. My simple brain would say that using quali mode carries a deal of risk in that it puts maximum stress on the car that still has to go another 43 laps at full chat. Pity it hadn't rained today. That would have been a bit more interesting.
