Interview with Ferrari's designer, Rory Bryne
Q: Tell us about the advantages of this new car?
Rory Byrne: The 2000 Formula One car is the first to be conceived entirely in our new wind tunnel. It incorporates a fundamental revision of the placement of the main masses, including a new V10 engine, to optimise the weight distribution.
We have also achieved a significant reduction in the height of the centre of gravity. This helps tyre wear in a race. In '98, the overall width of the car was narrowed another 200mm and the narrower the regulations make the car, the more important it is to reduce the height of the centre of gravity. The effect on tyres is one of the most important aspects, but there are others such as reduced roll, improved aerodynamic efficiency. It's one of those areas where you lower it as much as you practically can.
We have also incorporated a number of characteristics which will be obligatory for the coming years, to improve driver comfort and safety.
Q: So where has the main performance improvement come from?
Byrne: I think the main improvement in performance comes from the aerodynamics. In this area, we have made the biggest step forward since I joined Ferrari. I think part of the improvement is because we've done all the development in the new facility, rather than the old one, and it's due partly to the effort that the aerodynamic department has put into this car. It was started a lot earlier than last year's car and that's paid off.
The transmission is all new and incorporates new materials and processes. Its lubrication system has been revised to save weight and improve efficiency.
On the suspension side, we have a new system for the springs and the height adjustment and for the first time, all the main components are made from carbon composite. The power steering system has also been revised. We are using torsion bars with the suspension but the fundamentals of the suspension are different this year.
The fuel system has been completely redesigned to improve performance in both qualifying and the race, when it will be possible to reduce the time taken to refuel. In terms of fuel capacity, it's something we review from year to year and we've reviewed it for this year, but I'm not prepared to say what we've done.
In terms of the fuel flow, the FIA regulates the flow delivered at the nozzle but there are other areas where you can gain a small advantage if you're careful. You can certainly lose it if you're not careful.
There is a new Step 9 Marelli electronic system which improves the management and data acquisition system on the engine and car.
Q: Has regulation stability helped?
Byrne: The longer the regulations are stable, the more difficult it is to make big gains, so I'm quite pleased with the gains that we've made, bearing in mind this is the third year of similar type of regulation. There are always places to look for improvements, but it gets more difficult. You need to put in more effort, but I don't believe we'll ever come up against a brick wall, not with the current rules. There's still scope for development.
Q: You've tested on your own at your own test tracks for the past couple of years? Has that been a good or bad thing?
Byrne: Whether we test at Barcelona or Fiorano or Mugello I don't think is going to make very much difference on our first race competitiveness. We're going as hard as we can and we're going to be introducing updates and modifications during this test programme to give yourselves maximum competitiveness for Australia. Whether we test at Barcelona or Mugello will not actually test our performance. We feel it is much more important to be close to base so that we can attend to any problems much more quickly; the whole logistics is much easier.
Q: Are you running full scale models in the wind tunnel at the moment?
Byrne: We're mostly running a fifty per cent model in there at the moment, but there is provision to run a full scale model and we'll review that in due time. We have two models at the moment but we're constantly reviewing that and upgrading our facility and capability. That may increase in the future.
Interview with Ferrari Engine Chief Paolo Martinelli
Q: It's sounds as though the 049 is a brand new engine. How new?
Paolo Martinelli (head of the engine department): Although it is based on the 048 in terms of concept, it is a brand new engine from a structural point of view. Most of the components have been redesigned. It ran for the first time on the bench in the middle of October. At first, we concentrated on performance, but now we're working on reliability and simulating race distances on the bench. It hasn't run in a car yet, because it has been designed to run in the new car and it hasn't been possible to put the new engine in the old car.
Q: What were you looking for in developing the new engine?
Martinelli: The engine project had to meet two specific technical objectives:
- it had to have improved performance with more power and better driveability, while retaining the necessary reliability of its predecessor, the 048
- it had to mate perfectly with the car itself. This led to a development programme aimed specifically at lowering the centre of gravity and a new layout of the ancillary components.
The engine was developed at the same time as the car to ensure a strong integration of both parts.
As for its structure, the engine block is completely new, produced using microfusion technology, while the heads are an evolution of those from the 048.
