FIA ends blown exhaust era for 2014
F1's 'blown exhaust' and 'Coanda' era will be definitely over in 2014.
Germany's Auto Motor und Sport reported on Friday that the FIA has dictated that the turbo V6s only have one exhaust outlet, and that it must exit beyond the diffuser.
That will mean that, unlike in previous years, the phenomenon of engine exhaust gases having an aerodynamic effect will be almost completely removed.
Even the "area behind the exhaust pipe is a forbidden zone", Auto Motor und Sport added.
