This season, rather unusually, Ferrari have found themselves trailing the likes of Brawn and Red Bull in Formula One and they have desperately been searching for the reason why. Is the whole F60 concept flawed? Is it simply a problem of the new KERS system or the other teams' use of a double diffuser? Perhaps an aerodynamic solution is the way forward? And in this department, the French might have an idea. The shell of this Citroen 2CV has had a makeover (albeit without the benefit of a wind tunnel) and has been beefed up with Ferrari power under the bonnet. The result cost somewhere between 180,000 and 250,000 euros. This would at least solve Ferrari's difficulties with the proposed budget cap for 2010 and perhaps persuade them to sign up for next season after all.
