Formula One News » New Williams FW35 exhaust system “illegal” Posted on 19/02/2013
On the day they launch the FW35, Williams have been told that their exhaust system is illgal.
Mike Coughlan spoke earlier in the day about the exhaust system saying “Ours is OK, because if you look at ours it’s actually not a single piece it’s two pieces. The rule is an aperture size, and ours is an aperture size; ours is one aperture because it’s joined by a small piece in the middle, You’re governed by total aperture size, but singular aperture, and ours is a single aperture joined by a very small slot. So it’s actually two pieces, if you look closely you’ll see.”
But later in the day the FIA deemed the system illegal.
Article 3.8.5 of the FIA’s technical regulations which states that: ‘Single apertures either side of the car centre line [are permitted] for the purpose of exhaust exits. These apertures may have a combined area of no more than 50,000mm2 when projected onto the surface itself. No point on an aperture may be more than 350mm from any other point on the aperture.’
