Apr.1 (GMM) BMW, McLaren and Ferrari have confirmed that they have each commenced working on controversial 'double decker' diffusers.
We previously reported that Red Bull and Renault are going down the same path, despite their looming FIA appeal hearing against what they claim is a misguided interpretation of the 2009 rules.Red Bull's Christian Horner said the team's design department began investigating the solution weeks ago.BMW-Sauber team boss Mario Theissen is now quoted in the German press as saying: "We cannot afford to wait until somebody says it is allowed or not allowed."Mercedes' Norbert Haug added: "Naturally you have to prepare in case it becomes fully legal. Every team that wants to win must work on it (the diffuser)."Media reports say the cost of Ferrari's work on accommodating a double diffuser, involving substantial revisions to the entire F60, has been estimated at 20 million (euros)."We are basically having to build a new car," an unnamed Ferrari team source is quoted by the Munich newspaper TZ as saying.
