While the basic design elements are not new, the modern airbox wing on the FW30 is an excellent example of the current level of development in Formula One. Some teams are use very basic or no aerofoils in this area, but Williams appear to have put great effort in it. The image clearly shows a variation in chord along the width of the winglet. On top of that, the wingtip is slightly pointing upwards. The reason behind it is hard with any simulation, but any aerofoil in this area is important for air stabilisation in order to slightly improve the efficiency of the rear wing.
