Engine makers to discuss turbo V6 sound in China 11 April, 2014 Formula 1’s three engine makers will discuss how to turn up the volume of their controversial V6 turbo Power Units ahead of the Chinese Grand Prix. Germany’s Auto Bild reports that Mercedes, Ferrari and Renault will get together next Thursday ahead of the race in Shanghai. Although dominant Mercedes has ruled out agreeing to any mid-season rule changes, the German marque is open to discussing ways to make the engines louder to appease disappointed fans. Auto Bild reports that one proposal made by Mercedes is to simply look into sound amplification. That is because “Mechanically, [making the engines louder] is not so easy,” insisted Mercedes engine boss Andy Cowell. (GMM) Subbed by AJN.
