Which is the loudest car in F1?
Team Mercedes has produced the loudest Formula 1 car in 2011.
That is the finding of the German newspaper Bild am Sonntag, after testing the volume of this year's field trackside in Monaco just over a week ago.
The silver W02 registered 127.8 decibels, which is louder than the average human pain threshold, and nearly as loud as a military jet aircraft take-off with afterburner at 15 metres.
The Renault comes next at 127.5 decibels, followed by McLaren-Mercedes (127.3) and Renault-powered Red Bull (127.1).
The quietest F1 car this year is the Cosworth-powered Virgin, at 125.9 decibels.
Bernie Ecclestone has cited the awesome sound of the current crop of F1 cars as his main objection to the proposed four-cylinder turbo rules for 2013.
The FIA acknowledged that the 2013 debut could be delayed.
"In consultation with the main stakeholders, and following the outcome of this consultation, a fax vote by the World Motor Sport Council could be considered by 30 June latest to redefine the implementation date", the governing body said after its Barcelona meeting.
