Williams FW31 - rear diffuser 'hole'

From this angle you can clearly see the controversial opening (in yellow) in the protested Williams diffuser. This brings more air into the central part of the diffuser, allowing it to work harder to increase downforce. Most rivals believe this hole to be against the spirit and/or wording of the regulations and the design's legality will be considered by the FIA's International Court of Appeal on April 14. Also note the small splitter in the central diffuser.

　　從圖上角度可以清楚看到威廉斯賽車備受爭議的擴散器開孔(黃色標記部分)。這樣可以使更多空氣流到擴散器的中央，提高擴散器效率增加更多下壓力。其他的車隊大部分認為這個設計已經有違反或牴觸規則的嫌疑。這個設計的合法性將會在4/14的FIA的國際法庭上提出討論。也會討論擴散器中央的小開孔設計。
