Mercedes’ rivals may block megaphone exhaust 10 May, 2014 Mercedes’ rivals may block the introduction of the megaphone exhaust system, according to reports. Already utterly dominating the 2014 season, Mercedes will try the trumpet-like exhaust attachment at Barcelona during next week’s post-Spanish Grand Prix test. Earlier reports suggested that, following widespread criticism of the milder sound of this year’s engines, the Mercedes exhaust would get Formula 1’s volume half-way between the volume of the current V6s and the old, screaming V8s. But before the exhaust can be introduced at grands prix, “the other manufacturers, Ferrari and Renault, would have to agree”, Austria’s APA news agency reports. “They fear that Mercedes has made the development for its own benefit,” the report added. Mercedes Chairman Niki Lauda hit back: “It changes the horse power of the engine by zero. The only thing that changes is the funnel at the end of the exhaust. “It just makes more noise,” he added. “Everyone thinks Mercedes has done this to have an advantage – what absolute nonsense.” He claims that Mercedes was the only team that responded to the cries of the fans for more noise. “The others have not done anything,” Lauda is quoted by Bild. Nonetheless, he said that the Mercedes solution can simply be attached to the end of any exhaust – including those of rival Renault and Ferrari engines. Lauda said that initial tests had shown that, with the attachment, “you can reach almost twice the volume” of the current V6 engines. “The problem,” he explained, “is that all the teams would have to agree. Just because of that it won’t happen? What nonsense,” Lauda charged. Rival engine maker Renault confirmed that it is not convinced Formula 1 has a sound problem. “Take, for example, the most famous race outside of Formula 1, which is Le Mans,” Renault chief Jean-Michel Jalinier is quoted by Speed Week. “Last year I was there and there were more than 70 cars in the field, and yet it made less noise at the start than our 22 (Formula 1) cars. But no one complains that Le Mans is not a fantastic race,” he said. “If GP2 is louder, it just means that GP2 is outdated rather than Formula 1 having a sound problem. You just have to move with the times,” Jalinier argued, “and it is no longer the time for a V10 or V8 using 60 litres of fuel every 100 kilometres.” Interestingly, it seems that Mercedes’ efforts to introduce the ‘megaphone’ may not be blocked at least by title rival Red Bull. “The test next week is a step in the right direction,” said Helmut Marko. “GP2 is now louder than Formula 1, which cannot be.” (GMM) Subbed by AJN.
