Mercedes set to ditch Coanda exhaust

Mercedes is set to abandon its Coanda-effect exhaust for the final race of the season in a bid to try and get a better understanding of its tyre situation. After Nico Rosberg reverted to the non-Coanda design in Austin to assist the team's 2013 development programme, the team has elected to switch both its drivers to the old version for the final weekend of the season.
