Red Bull Racing has lost whatever advantage was gained from its engine-map trick, which was revealed by FIA Technical Delegate Jo Bauer in Hockenheim. Red Bull successful argued that its interpretation of the rules was possible, even if it was not what the FIA had intended and the FIA Stewards in Germany had no real choice but to accept the argument, even though one got the impression that they were none too happy with allowing the team to get away with it. The statement they issued noted that the team has not in breach of the rules as written, but clearly said (in an unspoken fashion) that this did not mean that he team was in the right when it came to what the rules was intended to say and, indeed, to the spirit of the rules. The best description that can be used is that Red Bull found a loophole in the rules and exploited it, while the other teams read the rules as they were intended to be read.
One cannot really blame the team for doing this. If there is a hole in the rules, engineers are paid to find it and exploit it to the maximum. This is what Red Bull did. The hole, however, is now closed and it will be interesting to see what effect this has on the team’s performance in the races ahead.
