Dispute brewing between Mercedes, Renault and Ferrari 25 January, 2014 Mercedes V6 turbo Formula 1 engine Reports have emerged that even before the new V6 turbo engines are fired up in anger, a dispute is brewing between Mercedes, Renault and Ferrari. Auto Motor und Sport reports that the dispute is over whether a protective cover for the turbocharger, weighing a crucial 3 or 4 kilograms, is necessary. Mercedes and Renault argue that the cover is needed for safety reasons in the event of a turbo failure, but Ferrari wants to leave the cover off. “Next week there will be a clarifying conversation with the FIA,” wrote correspondent Tobias Gruner. “Renault will apparently show a film of what happens when a turbocharger explodes.” (GMM) Subbed by AJN.
