The 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.
While retaining the longitudinal architecture for the transmission, the
entire rear end has been changed in an attempt to get the most out of
the size of the gearbox, which is smaller than its predecessor and made
from titanium and carbon fibre. Naturally, the limitations introduced by
the new regulations were taken into account during the design stage.
The rear suspension has been revised, with the twin aims of improving
the car’s dynamics in order to optimise the efficiency of operation for
the Bridgestone tyres, while also improving the aerodynamic efficiency
of the rear. The floor of the car has also been substantially redesigned
to fit in with the new dimensions of the gearbox and comply with the new
regulations. Two areas that benefited from a major effort during the
design stage were the braking and electronics systems, this work carried
out in conjunction with technical partners.
The 055 engine is load-bearing and mounted longitudinally. Much of the
internal componentry derives from the last version of the 053, currently
fitted to the F2004 M. The main changes centre on the mounting points to
chassis and gearbox. Its designers aimed to come up with an engine able
to maintain a sufficient level of performance, doubling its life given
that the sporting regulations introduced this year require the use of
the same engine for two consecutive race weekends. As always, Shell’s
help has been invaluable in the definition of fuel and lubricants to
best meet the set targets.
The F2005 represents the final evolution in a line of Ferrari Formula 1
cars fitted with a ten cylinder engine. As usual, right from the design
stage, much attention was paid to performance and optimisation of the
materials used as well as quality control, in order to increase
performance levels with maximum safety, all within the framework of the
new rules introduced this year.
