Automotive News - Feb. 26, 2005 MARANELLO, Italy - 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.

"F2005 Aerodynamics" "The shape has been revised, with modifications to the opening of the side pods and the area around the turning vanes."

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.

Byrne explains design of F2005  

Ferrari's Rory Byrne explains how the regulation changes affected the design of the F2005

"Although the fundamental design philosophy of the F2005 is the same as previous cars, the changes in bodywork regulations have meant that we have also had to maximise downforce in order to recover as much as possible of the 25% we lost initially."

"Changes to regulations which now require only one set of tyres to be used for two qualifying session and the race have meant we have had to consider tyre life as well as performance so, as usual, many areas of the car have had to be fundamentally revised in order to make a step in performance."

"I will explain in more details:

1) Aerodynamics The areas directly affected by the new regulations, eg wings and diffuser, are obviously all new but even radiator, exhaust and gearbox layouts have been fundamentally revised to optimise the aerodynamics. In addition, there are several development items planned to be introduced during testing in the next month so when it first races it will look differently in some areas to the car you see here.

2) Transmission While the transmission internals have been further optimised, the casing is completely new, both in terms of its shape to optimise the aerodynamics and its method of construction and use of materials. A prototype has been successfully tested in the F2004.

3) Chassis The chassis is completely new, both in terms of shape, which is a result of the aerodynamic development programme, and in terms of materials used and design of the structure, in order to achieve a weight saving in spite of the increased side penetration requirements for 2005.

4) Suspensions, steering and brakes Both front and rear suspensions have been further optimised to maximise performance and minimise wear of the Bridgestone tyres. A fundamentally revised power steering system to enhance driver control in transient conditions will be tested shortly. More effort than ever before has been spent on optimising the braking system in order to improve the driver use and modulation of the brakes during qualifying and the various stages of the race.

5) Electronics For the first time, a Ferrari designed and developed data acquisition system has been installed in the F2005 in order to greatly enhance the data acquisition and processing. A prototype of the system has been successfully tested on the F2004."

"Aldo Costa has been responsible for the entire F2005 project and I would like to congratulate him and his team who have carried out the research, structural calculation and design of the car and met all the objectives we defined at the start of the project."

"Finally, I would like to thank everyone at the Gestione Sportiva for their contribution in producing the best ever Ferrari Formula 1 car. Forza Ferrari!" (FERRARI)

The Ferrari 055 engine

Paolo Martinelli, Ferrari's head of engine development, talks about the new 055 engine

"The new F1 engine -- a 90 degree V10 -- which will be used for the forthcoming championship, fitted to the F2005 is called the 055.

To comply with the new regulations, that stipulate the use of just one engine per car for two races, engine life must once again be doubled, compared with the previous year: we have thus moved from 400 km in 2003 to 700 km last year and now our target is 1400 km. Furthermore, it will be imperative to have performance stability over the entire period of engine life (as engine usage will run to the end of the second race.)

The 055 engine began life as an evolution of its predecessor (called the 053.) A great deal of work in terms of design and experimentation was and will be focussed as a priority, on meeting and maintaining the necessary reliability for this new mission profile. One has to taken into consideration that for many of the engine's internal parts, especially those that move, the 1400 km range is a severe test that conflicts with maintaining performance.

Therefore, most of the engine components have been redesigned and effectively optimised to meet the new targets. The engine will be adapted in terms of "mapping" as a function of the various requirements during the season (I mean for example, the demands of various circuits that come up on the 2005 F1 calendar and the different weather conditions we can expect.)

The 055 engine design project had to meet the following technical demands: * reliability extended to around 1400 km -- as already explained -- while maintaining necessary levels of performance and driveability; *consolidating strong integration with the design of the car, which has led to a functional optimisation of layout of the engine and its accessories.

The 055 can only be fitted to the new F2005 car.

As for its structural characteristics: the block, heads and other minor castings have been strengthened without any appreciable increase in weight. All moving components are new to cope with the extended life. The Marelli engine control unit has also evolved to meet the 2005 requirements, with new electronic components. It also proved necessary to develop a new fuel and above all, a new lubricant, with invaluable support from Shell, that provides exceptional stability and engine protection.

In terms of performance development, work will go on throughout the season, with evolutionary steps already planned in the programme.

The team of Ferrari engine engineers continues, through the stability of the group, to grow in experience and responsibility, both in design and development (with a strong team of specialists in all areas: combustion, dynamics, bench testing etc.,) and in the running of the engine on the track.

Our engine department has a long history, but it is always heavily orientated towards innovation and improvement in terms of product and work methods. The organisation has been adapted to meet the new aims of the 2005 season.

It is impossible for me to mention here all those involved, but I want to single out Gilles Simon, who was in charge of design, as indeed he was for the previous V10. Supporting him on the development side will be Lorenzo Sassis. Track and reliability testing of the engine will be supervised by Noel Cavey and the race engines will be run by Mattia Binotto. The support of our technology-production side (which we call Meccanica GES) and quality control is also fundamental. It is under the leadership (not just on the engine side) of Mario Almondo.

Finally, no power figure is revealed, but, without wishing to sound repetitive, I can guarantee that again this year, all Ferrari's engine crew will work methodically and with determination to ensure there is "sufficient" horsepower, delivered in "driveable" and "reliable" manner to reach our targets for the 2005 F1 championship. All that remains is to wish all our partners and suppliers a successful year and Forza Ferrari!" (FERRARI)
