Williams scraps controversial Coanda exhaust trick 25 February, 2013 New Williams FW35 exhaust outlet Spurred by suggestions from the FIA, Williams has removed the controversial layout of its Coanda-effect exhaust from its new FW35. Despite designer Mike Coughlan believing his layout cleverly exploited a loophole in the rules, the FIA reportedly told the British team its solution was not legal. “Charlie Whiting was here yesterday,” British broadcaster Sky’s pit reporter Ted Kravitz said on Friday as the Barcelona test concluded. “(I think) he went to Williams and had a quiet word in their ear that they might want to take that (exhaust solution) off. We don’t expect to see it reappear given the FIA’s stance on that,” he added.
