Mercedes is preparing to show off a louder engine note during the Spanish Grand Prix weekend. Early this week, team chief Toto Wolff revealed that one proposed solution to the turbo V6 sound ‘problem’ is a sort of “megaphone” addition to the exhaust.

Along with Ferrari and Renault, F1′s three engine makers have been considering how to spice up the sound of F1 2014, after some spectators and promoters were shocked at the difference compared to the screaming V8s of 2013.

“The solutions range from very complex solutions within the exhaust system down to a simple megaphone at the back,” Wolff is quoted by Kolner Express newspaper.

“The ‘megaphone’ is a parallel exhaust that simply opens up at the end, with all the problems that brings with it,” the Austrian added.

Insiders say Wolff is concerned that the solution will interrupt the thermal and aerodynamic integration between the ‘power unit’ and the current exhaust layout.

Nonetheless, he said that sound solutions will be tried on the W05 car at the post-race Barcelona test next week.
