FIA Race Director Charlie Whiting says that, no more plans for another sparks test or megaphone test for noise issues in the new generation V6 turbo engines, when the Autosport correspondent ask him during the media conference.
The brand new V6 turbo engines are remarkably silent than the previous seasons used V8s and most F1 fans criticized the quiet noise at the start of the season. At an in-season test in Barcelona Mercedes experiment a megaphone exhaust, but that concept was lost.
“Noise is something that we’re still working on. A solution that has been tested on a dyno is to split the exhaust. We’ve [currently] got one tailpipe in the centre of the car where all the exhaust gasses come out.”
“We did this purposefully to minimise the effect of the exhaust gasses [on aerodynamics] because, as you know, we’ve had lots of problems with the rules on exhausts.”
“What they’ve found is that by splitting that exhaust, you do get more noise. It would seem to work, especially with megaphones, be they round or rectangular, to some extent. The next step is to look at the feasibility of doing it. If you’re going to put a megaphone or two on the back of a car, there’s a lot of interaction between wing pillars, rear wings, monkey seat wings, rear impact structures, rear lights.” He added.
“All those sorts of things would have to be re-engineered, potentially, to accommodate two exhaust pipes instead of one. It’s not a straightforward job. And I think the next step it to assess whether or no everyone feels this is a worthwhile thing to do. That’s where we are.”
