The car was named after its V8 engine: 24 is the capacity in decilitres, and 8 the number of cylinders. The name broke the F200x system used from 2001 to 2005 and returned to a system similar to that used in the 1950s and 1960s ("cf." Ferrari 312) but they did revert to the previous system the following year with the F2007. The 248 model was driven by race drivers Michael Schumacher and Felipe Massa. The 248 F1 was the first Ferrari since the F1-2000 not to wear the number one, denoting that the driver is world champion. The car also featured new sponsor decals such as Martini. This was also Vodafone's last year of sponsorship for the Scuderia as they announced that they would switch to McLaren Mercedes as title sponsor. Ferrari used 'Marlboro' logos in Bahrain, Malaysia, Australia, Monaco, China and Japan.
