The FIA has moved to increase the noise of Formula 1 cars for 2016 after changes to exhaust set ups were approved by the World Motor Sport Council.
The quieter 1.6 litre turbo hybrid power units have been the subject of plenty of criticism from both fans and key figures in F1 for their lack of noise since being introduced in 2014.
Mercedes had trialled a trumpet exhaust last season but the FIA has concluded that the introduction of a separate watergate tailpipe alongside an exhaust tailpipe will solve the issue.
“For 2016, all cars must have a separate exhaust wastegate tailpipe through which all and only wastegate exhaust gases must pass,” read a statement from the FIA.
“This measure has been undertaken to increase the noise of the cars and will not have any significant effect on power or emissions.”
The FIA also ratified a number of other minor changes to the Formula 1 regulations for next season, including clarifying the issue of track limits.
While penalties will still be awarded based on whether a driver has gained an advantage by heading off course, the sporting regulations have been updated to stress that drivers ‘must make every reasonable effort to use the track at all times and may not deliberately leave the track without a justifiable reason’.
Reporting and inspection processes for wind tunnel and CFD usage will also be beefed up, alongside tweaked rules for engine and gearbox change penalties.
“Such penalties prior to qualifying will be applied based on the time of use,” read the statement.
“For changes made after qualifying, preference will be given to the driver whose team first informed the technical delegate that a change will occur.”
Additionally, drivers who cause an aborted start will now be required to take the second start attempt from pitlane, rather than re-taking their grid position or lining up at the back of the field.
