Following the allegations regarding the legality rear diffusers of those three cars – Toyota TF109, Williams FW29 and BGP 001 – the Australian steward spent no less than 4 hours discussing the concepts with several F1 teams before finally giving their blessing.
As expected, Ferrari, Renault and Red Bull have all lodged a protest against the aforementioned designs, arguing they are illegal. BMW Sauber also wanted to join the pack, but their protest was not recorded because of some irregularities regarding the submission timeframe.
Although none of those 4 teams have officially announced it, they will more than likely take the protest to another level, naming the FIA International Court of Appeal. However, this next (and final) step will only bring light into the matter shortly after the Malaysian Grand Prix, when the next meeting of the aforementioned body is scheduled.
That means all three teams in question will race under appeal for the upcoming 2 races, until a final decision is made.
“We are pleased with the decision of the race stewards but we prefer not to comment further on the situation. This weekend promises to be a tremendously exciting Australian Grand Prix so we are now looking forward to starting the competition on track with the first practice sessions on Friday,” said Toyota Motorsport Chairman Tadashi Yamashina after the stewards' decision.
