2005 Ferrari F2005
(from Ferrari Press
Release) 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.
