Louder engines will make a comeback in 2016 after approval was given for alterations to the current exhaust system.
The noise of the new smaller turbo engines has been heavily criticised since their introduction in 2014, leading to research into ways of boosting the volume, one of which included fitting a trumpet-like attachment to the single exhaust tailpipe.
The solution, which has been ratified by the World Motor Sport Council, will see a second tailpipe added, but only “wastegate exhaust gases” may pass through it.
“For 2016, all cars must have a separate exhaust wastegate tailpipe through which all and only wastegate exhaust gases must pass,” read a WMSC statement.
“This measure has been undertaken to increase the noise of the cars and will not have any significant effect on power or emissions.”
Other minor changes include a clarification on track limits, with the following statement added to the Sporting Regulations: “Drivers must make every reasonable effort to use the track at all times and may not deliberately leave the track without a justifiable reason”.
Penalties will continue to be based on whether race control deems a driver to have gained an advantage.
Meanwhile any driver who forces an aborted start will no longer be permitted to rejoin the grid, they will instead have to start the race from the pit lane.
