Noise levels won't increase

Renault have quashed any hope that Formula One could raise the noise level of the new engines as it would require a shift in the regulations.

The 1.6-litre turbocharged V6 made their debut in Australia but fell flat with many Formula One fans.

Equating the noise to vacuum cleaners and hair dryers, reigning World Champion Sebastian Vettel summed up the general opinion when he said the sound was "s**t."

There had been talk about the possibility of increasing the noise levels, something F1 supremo Bernie Ecclestone suggested.

However, according to Renault's head of track operations Remi Taffin that is not possible.

He explained to Autosport: "There's two big items that drive this.

"Firstly revs: we went from 18,000 to something like 12,000 this year.

"It's important to say it's based on the regulations, because they set 15,000 as a maximum, but the fuel flow limitation means the maximum we're running, whether it's a Ferrari, a Mercedes, or a Renault, is 12,000 and at the end of the straight it could be 10 or 11,000.

"This makes a very big difference, because last year it was 18,000. Now where you've got grandstands it's something like 10.

"The other item is the turbo. You put one thing through the path of the exhaust gases, which is like if you would put a pillow on someone's face. It acts as a muffler.

"If you combine these two, we've got the result we've got."

And while increasing the revs alone would improve the sound, Taffin revealed that is not possible given the sport's fuel flow limit of 100kg/h.

"If you want to have a different noise you have to go up on revs, but there would be no point going up on revs if you look at the fuel flow, because you would have to get the fuel flow up. But then you bring get your efficiency down.

"There's nothing you can do with exhaust profiling because again you've got both exhaust pipes running into the same tailpipe after it has run through the turbo, so it is what it is."
