The F10 is the fifty sixth single-seater built by Ferrari, specifically to compete in the Formula 1 World Championship. The name of the car renews the tradition of being linked to the year in which it makes its debut in the Championship. The project, which went by the internal code number 661, represents the Scuderia’s interpretation of the technical and sporting regulations which apply this year. The rule clarifications issued by the FIA during the course of last season as regards the diffuser, have opened up new scenarios for the designers in terms of freeing up this area, thus presenting the opportunity to deliver potentially great performance advantages.
Compared to the F60, the F10 was obviously conceived with the aim of maximising the aerodynamic performance of the double diffuser. Therefore the engine mountings to the chassis have been modified in a specific way and also redesigned is the shape of the gearbox casing and the rear suspension layout. It only takes a quick glance to note that the front part of the chassis is considerably higher than on last year’s car and that the central upper and lower surfaces are hollowed out, in order to improve airflow. Another major rule change is that race refuelling is banned, which means the fuel cell has to be big enough to allow the car to get to the end of the race, whatever the type of circuit.
Inevitably, the car is longer to accommodate the new fuel tank and to allow the installation of longer narrower radiators, so that the sidepods have a smaller higher aperture, with a more cut out shape at the bottom. A further tapering has been achieved thanks to a revised and unconventional configuration of the exhausts. The need to start the race with a much heavier car than in the past has required a redesign of the basic characteristics of the braking system, carried out in conjunction with Brembo, as well as a new design for the relevant cooling system. Safety levels have been increased thanks to the introduction of new crash tests for the rear bulkhead and the cell with a full load.
In light of past incidents and the fact that pit stops will take less time, the wheel nuts have been updated so as to increase security when the car is sent back out on track. The 2010 technical regulations contain other new elements: some components (the chassis, nose, side and rear crash test structures) must be homologated for the entire season; some wheel rim dimensions have changed and wheel flanges are banned. It is also compulsory to use less sophisticated materials in the construction of some components and there is a restriction on the number of gear ratios that can be used during the season.
Furthermore, other changes include an increase in the minimum weight to 620 kg and the use of narrower front tyres; the latter should have been an incentive to use KERS, although, at least for this year, this system has been dropped by common agreement of all the teams. This has led to a redistribution of the accessories on the 056 engine, which is again mounted longitudinally in the F10 as a load bearing member. Not only are the 2010 tyres smaller, they will also feature different compounds and construction to those of last year.
