Mercedes decide not to test megaphone exhaust in FP1 9 May, 2014 Mercedes will test a new their megaphone exhaust next week, but not during Friday practice for the Spanish Grand Prix. It had been claimed the Brackley team may run its prototype design, aimed at increasing the volume of this year’s turbo V6 engines, in Free Practice. But a Mercedes spokesman told the Austrian news agency APA that the exhaust attachment will actually only make its debut at the post-race test. “We’ll see there if it has the lasting effect that we want,” team boss Toto Wolff is quoted. APA said that the results of Mercedes’ exhaust test will be sent directly to the FIA, who will decide on the next steps. “The aim is to find a workable solution for everybody by the Canadian Grand Prix on June 8,” the report revealed.
