Ferrari 248 F1 - Technical specifications
Mugello, 24th January 2006 - The 248 F1 is the fifty second
single-seater built by Ferrari specifically for use in the
Formula 1 World Championship. The project, which goes by the
internal code of 657, represents the Scuderia's interpretation
of the technical regulations which apply in 2006; the main
new feature of which is the introduction of an eight cylinder
V configuration engine, with an overall capacity of 2400 cubic
centimetres. In fact, the name of the car derives from these
key figures relating to the power unit. The chassis of the
248 F1 is lighter than that of its predecessor and its shape
has been revised, with modifications to the openings of the
side pods and in the area of the deflectors. The cooling system
has been substantially revised and not simply to meet the
needs of the new engine. The location and size of the rear-view
mirrors is one of the most obvious novelties. Other significant
changes include the engine air intake, the engine cover, the
size of the fuel cell, the aerodynamic elements on the side
pods and the layout of the exhausts. The gearbox - seven speeds
plus reverse - represents an evolution of the carbon one introduced
on the F2005 and it continues to be mounted longitudinally.
The front suspension continues the classic design for Maranello
single-seaters. However, the rear suspension has been designed
to meet a key objective, which is to increase the overall
aerodynamic efficiency of the rear end and to mechanically
improve the usage of the Bridgestone tyres. This work was
also supported by the Fiat Research Centre. As key elements
to achieve these objectives the aerodynamic design of diffuser
and the floor of the car have been extensively redesigned
and in collaboration with Sachs, particular attention was
paid to the dampers. As was the case last year, extensive
design work went into the electronic installations, with the
support of Magneti Marelli. Continued co-operation with Brembo
has enabled another step forward with the braking system.
The 056 engine is load-bearing and is fitted longitudinally.
Design work began back in the spring of 2005 and naturally,
took into account the strict limits laid out in the FIA technical
regulations, in terms of the angle of the V, weight, dimensions
and centre of gravity. The first example of the V8 engine
ran on track in the month of August and development was initially
carried out with it fitted to an F2004. As was the case last
year, engines will again have to be used for two consecutive
grands prix in 2006. With this in mind, Shell's support has
been even more invaluable in defining the specification for
fuels and lubricants best suited to meeting set targets in
terms of reliability and performance. Driveability was another
important factor, when defining the new engine's characteristics,
with the regulations requiring fixed inlet trumpets: engine
management is controlled by an integrated injection and ignition
system from Magneti Marelli. The 248 F1 renews a tradition
for Ferrari Formula 1 cars fitted with V8 engines, last seen
in 1964 with the 158 F1. As usual, great attention is paid
to the behaviour and optimisation of the materials used, from
the design phase and through quality control, always striving
to maximise the level of performance and to achieve the highest
possible levels of safety.
