The Renault F1 Team's strategy mastermind, Pat Symonds, explains the impact of changes to the sporting regulations, on how the team will work during the race weekends in 2006.
Pat, the most significant change to the sporting regulations comes in the form of tyre usage, both in the race and through the weekend. What is your perspective on the change?
Pat Symonds: The first point is that we are once again allowed to change tyres during the race. This is not a step into the unknown because it marks a return to the sprint races we have seen since the mid-90s. The more interesting change, though, is how we use those tyres throughout the weekend. Unlike last year, we are now totally free and more importantly, we do not have to make our tyre choice until qualifying starts. In previous, years, we had to do so by Saturday morning. We can even start the race on new tyres and fit new tyres all the way through the race, if we choose to. The key thing is that we only have seven sets in total. Managing tyre usage is now a key strategic choice during the weekend.
What compromises will this involve?
PS: We need to balance the performance advantage that a new set of tyres can bring in the race, against getting all our set-up work done in practice. So first we have to decide how many sets we use in practice. We then need to decide how many sets of new tyres you want to use in qualifying – one, two or three? Ideally, we will use as few as possible, to keep them for the race, but will we be quick enough to get to the final qualifying session without them? How much advantage can we gain from fitting new tyres at a pit-stop in the race? The strategic benefit of this varies from circuit to circuit, so in some places we will want a new set in every stint – which could be up to four sets. There are many factors to consider in planning the structure of our weekend.
You will be using softer tyres throughout the race weekend – what does this change for the set-up, and strategies?
PS: The use of shorter life tyres requires a fundamental change to tyre development. We will be less worried about tyre wear in 2006, but problems like graining will become an issue once again. The car will be configured to use the tyres differently – we can be more aggressive in our set-ups if the tyres don't have to last for the whole race. Finally, it has an impact on strategy. Last year, everything converged to a standard "rearward biased" two-stop strategy, with longer opening stints. In 2006, I think we will see more pit-stops and more strategic variation, to take advantage of the performance gain from fitting new tyres.
The weekend format has also changed – will that affect the amount of running you do?
PS: The most significant change is that we no longer have to make our tyre choice on Friday evening. Track conditions are not generally at their best on Friday, but last year we had to run in order to understand the tyre behaviour and make an informed choice. That is no longer the case, as we only have to make our decision before qualifying, allowing us to run when track conditions are most representative.
Does that mean we will see less running on Friday?
PS: I think it almost certainly will. Those teams with the advantage of the third car will run a lot, but for the top four teams, there will be much less activity. The tyre situation is one reason, but we also have a longer qualifying procedure – which will use up engine mileage. We will be managing engine life very carefully once again in 2006, especially at the beginning of the year when all the teams will have brand new units. Everybody will look to save their running on Friday.
But presumably, you still have to run to establish a good set-up for the car…
PS: Of course, so what we are talking about is a change in the timetable of how we run the car. With a dry weather forecast, I expect we will do very little on Friday morning, a little more in the afternoon, and the majority of our work on Saturday morning, when track conditions will be at their best. That one hour session will be very busy!
Finally, we have a new qualifying format. What strategic complications does it bring?
PS: This changes according to where you expect to qualify. If you expect to be at the back, things are very easy; similarly, at the front, it is a bit more complex but not too bad. However, in the midfield, there is a melting pot of opportunities. Any cars outside the top ten are allowed to determine their fuel load after qualifying, so there is no doubt it is better to qualify 11th, when you will most likely use a heavy fuel load, than 10th. You can then calculate your strategy around longer stints that should allow you to overtake cars ahead during the pit-stops. This may lead to some jockeying for positions outside the top ten during the second qualifying session.
Will cars running in the final super-pole session, run lower fuel loads for the first race stint than those outside the top ten?
PS: In general, I think so. Cars competing in the super-pole have to start the session with their fuel load for the first stint. Obviously, there is an optimum fuel load to carry. But you now have to calculate whether you can burn off enough of this fuel during the twenty minutes, to set a lap on low fuel at the end – when the car is at its lightest, and therefore fastest. If not, do you choose a lower fuel load to improve your grid position? Or qualify further down the grid, but with a strategic advantage? Each team will strike a balance between the optimum race strategy, and the fight for grid position. For the cars outside the top ten, the logical thing to do is to carry as heavy a fuel load, as your tyres will allow you to. This will allow you to pit later, and perhaps make fewer stops, in order to gain track position during the race.
Do you expect the nature of the races to change?
PS: I think we will soon see a pattern emerge, with the front half of the grid racing off on lower fuel loads in the opening laps while the second half, with higher fuel loads, continue running as the front cars pit for the first time. Essentially, the top ten will run a "forward-biased" race – where the opening stints are short, like we saw in 2003 and 2004. For those cars outside the top ten, the optimum strategy will be "rearward biased" – with longer opening stints, and perhaps fewer stops, like in 2005. The qualifying format will split the race into two very distinct halves in 2006, at least in the opening stages.
