Williams could revert to 2012 exhaust

Williams could revert to the exhaust of its 2012 car, after struggling for pace and handling with the new FW35 so far this season.

Technical boss Mike Coughlan admitted to ESPN that the main problem has been the 'Coanda' aerodynamic exhaust principle, which Grove based Williams is using for the first time in 2013.

He admitted "We need to go away and get a more consistent platform for the driver".

"We're of the opinion at the moment that a FW34-type of car would be faster," said Coughlan.

"I don't think we'll go back to an FW34, but we might go back to an FW34-style of exhaust system and treat Fridays as tests across cars."
