The Ferrari cheating allegation scandal continues. Only nine days after Verstappen accused Ferrari of cheating at the US GP, the FIA sent another technical directive on possible tricks to get more power out of the engine. This time of their own accord. It basically states - "No oil from cooling systems into the engine".
It looks as if the FIA wanted to clear up the accusation once and for all that one or more teams could have unleashed more power by cheating.
