The Ferrari F2005 is the fifty first single-seater built by Ferrari specifically to compete in the Formula 1 World Championship. The design, which bears the internal code number 656, represents Ferrari's more exhaustive interpretation of the 2005 technical regulations. The main elements, relating to aerodynamics are more advanced than on the F2004 M.
The chassis is lighter, despite the need to strengthen the lateral anti-intrusion panels within the monocoque to increase its ability to meet the requirements of the crash-test, which is stricter than in the past. The shape has been revised, with modifications to the opening of the side pods and the area around the turning vanes. The side pods have been adapted to accommodate the new cooling system.
The engine cover has been redesigned, as have the aerodynamic devices on the side pods, with a secondary winglet introduced in the area of the roll-hoop. The layout of the exhausts is fundamentally different to that of the previous car, eliminating the aerodynamic profile which characterised the rear section, which is now almost entirely integrated within the bodywork.
