Bridgestone

Bridgestone’s super soft tyre proved to be the fastest rubber at the undulating anti-clockwise Interlagos circuit in Sao Paulo for the first day of the Brazilian Grand Prix as Fernando Alonso set a time of 1min 12.314secs in the afternoon practice session. Red Bull Racing driver Mark Webber set the fastest time in the morning practice session, using the super soft to achieve a 1min 12.463secs. Weather conditions were cool and cloudy all day with intermittent showers. In the afternoon session all drivers were separated by less than a second.

Q&A with Hirohide Hamashima - Bridgestone Director of Motorsport Tyre Development

What was significant about today’s running?
“The first day at Interlagos is always a challenge and today was no different. The track surface was dirty and wet from drizzle and the weather was cooler than we expected. The temperature meant that the medium compound took a little longer to warm-up. Even so, both compounds worked well. The super soft has more grip however we saw graining on the front and rear tyres. Some drivers reported a moving sensation from the rear with the super soft, and this is a characteristic of the softer compound rubber.”

How do you expect this allocation to work over the weekend?
“We have to look to the skies for the answer to that question. As we saw last year, rain can be a very big factor here and many forecasts predict more rain over the weekend. For qualifying with the temperature similar to today we can expect the super soft to be the favoured tyre. For the race the medium compound should be the favoured tyre, although some competitors might find good results with the super soft.”

Brawn GP

Brawn GP’s Rubens Barrichello and Jenson Button began the team’s on-track preparations for Sunday’s Brazilian Grand Prix at the Interlagos circuit in the city of Sao Paulo today. With the team’s focus on maximising the set-up of the BGP 001 cars for the race, Rubens and Jenson evaluated a number of different set-up options and tyre evaluations working with the Bridgestone Potenza prime and option tyres.

The morning practice session took place with light rain developing into a brief heavier shower thirty minutes into the session which kept the cars in the garage for a short while. The afternoon session was largely dry allowing the team to successfully complete the majority of today’s planned programme. Rubens completed 70 laps ending the day in third position at his home track, with Jenson totaling 74 laps in fifth position.

RUBENS BARRICHELLO: “Our focus today was on evaluating our set-up for the race and whilst the times may not have always looked competitive, the data that we gathered will be very useful when we study all the options this evening. The car felt better when we put the softer option tyre on towards the end of the day and I was able to put in a good lap. It’s great to finally get the track action underway today and I’m pleased with our progress and happy to be starting my home Grand Prix weekend at the top end of the field.”

JENSON BUTTON: “We achieved more running that we initially expected today with just a few little showers rather than the rain that was forecast. The car seems to be working well on the prime tyre which is encouraging and the pace was good. I’m struggling a little with the balance on the option tyre over one timed lap so hopefully we can resolve that overnight to be ready for qualifying.”

ROSS BRAWN: “We had two good practice sessions today and are reasonably happy with our position at the end of the day. The balance of the cars improved this afternoon and both Rubens and Jenson are fairly comfortable with the set-up over longer runs. We still have some work to do overnight and ahead of qualifying to ensure that we achieve the best one-lap pace tomorrow.”

BMW

The first two free practice sessions for the Brazilian Grand Prix were held in inconsistent weather conditions with periods of light drizzle in both sessions. For the BMW Sauber F1 Team the day went without any technical problems. Robert Kubica and Nick Heidfeld reported progress in terms of car balance and set-up in the afternoon, but were still not happy.

Robert Kubica: “Today, we tried different downforce levels and completed some long runs in preparation for the race. However, it was very difficult to get reliable results because on several occasions it was drizzling, and the conditions were changing frequently during the two sessions.”

Nick Heidfeld: “We changed the car a lot after the first session when it really wasn’t good at all. The changes definitely meant an improvement, but the balance isn’t yet as I would like it to be. We still have some work to do. The track is better than expected, so I can’t complain about any changes for the worse since last year. There are still bumps, of course, but nothing to worry about.”

Willy Rampf (Head of Engineering): “As far as the track conditions are concerned, this was a mixed Friday for all teams. Again and again light rain falling made the set-up work difficult. We concentrated on race preparation and drove with different aerodynamic configurations. For tomorrow we will concentrate on qualifying. There is still work to do.”

Ferrari

It was a rather difficult day for Scuderia Ferrari Marlboro, tackling the first two free practice sessions for the Brazilian Grand Prix. Watched by Felipe Massa, making his return to a race meeting, even if only as a spectator in the pits, rather than wearing a race suit, the two F60s ended up towards the back end of the FP2 classification, while not managing anything better than tenth place for Kimi Raikkonen in FP1. “Clearly, we cannot be satisfied with the way things went today,” said Stefano Domenicali. “We definitely have a lot of work to do to try and improve the set-up of the car within the limitations of what we have to work with. However, we should also take into account how close the times are, with all twenty drivers out on track this afternoon setting times within the same second. It takes almost nothing to make the difference between being at the front or at the back of the pack. This means that everyone, drivers and team, will have to carry out their work perfectly if we aspire to getting a good result this weekend, starting with tomorrow afternoon’s qualifying.”

Giancarlo Fisichella: “Eighteenth and twentieth places in FP2 is not a result we can be happy about but, to use a footballing expression, it’s all looking very tight, as it has been in fact for much of the year. On top of that, we are also working a lot for 2010 which makes it even harder to understand precisely where we stand compared to the others. We are really struggling in the second sector, where what counts the most is aerodynamic downforce, an area in which the F60 does not really excel. Tomorrow, it will be vital not to make the slightest mistake to try and get a good qualifying result: here it will only take a tenth or even less to fail to make it past Q1.”

Kimi Raikkonen: “I’d say this Friday was not too different to others we have experienced this season, especially in recent races. It’s all very close so it will only take a small step forward to climb back up the order, but we are definitely facing a difficult weekend. The tyres suffered with a bit of graining, which made itself felt especially in the second sector, but I believe that, as often happens here, once the track rubbers in, the situation will improve.”

Chris Dyer: “It was a pretty difficult Friday, with very changeable weather, which prevented us from getting through all our planned programme. Furthermore, we had a problem with Fisichella that prevented him from doing his final planned run in FP2. There’s a lot of work to do to try and improve the car, which lacks grip, which is particularly noticeable in the second sector, where we are not really competitive. We were also experimenting with some mechanical elements aimed at next season: without any winter testing available before the new car makes its debut, we have to exploit every opportunity, especially given the situation in the championship.”

Red Bull

SEBASTIAN VETTEL: “All in all, a good Friday. We had another practice day without any engine trouble, even though we did a lot of laps – so thanks to Renault for that. Other than that, we were fast throughout the whole of practice today. We’ll look into the data now and I’m sure we can improve further – we should have enough time before tomorrow to make another step forward. Weather-wise, I think today was the day they predicted rain and it didn’t rain much, so maybe that means rain for Sunday?... We will see.”

MARK WEBBER: “We couldn’t have got much more out of today. The guys did a good job getting the optimum time on track that we could with the tricky conditions. We were dodging showers here and there, but we timed everything as well as we could. It’s one of the more encouraging Friday’s that we’ve had for a long time, so it was good. I hope it carries on tomorrow. We’ve seen that things can change day to day with this Championship, so I’m looking forward to qualifying – it should be good for us.”

Force India

Free practice for the penultimate race of the year, the Brazilian Grand Prix, got underway today at the Autodromo Jose Carlos Pace in the heart of Brazil’s largest city, Sao Paulo. The notoriously fickle South American weather again came into play, with light showers punctuating most of the day, making the timing for running crucial. The Force India Formula One Team performed well in the changeable conditions, with Adrian Sutil setting the 9th quickest time in both sessions.

Tonio Liuzzi was classified in 17th in the morning and 16th in the afternoon after hitting traffic on his potentially quickest laps. Adrian completed 58 laps in total, making the most of the dry periods as he worked through his planned tyre and set-up evaluation for the anti-clockwise Interlagos track. Tonio Liuzzi, participating in only his fourth race for the team this weekend, similarly worked through his scheduled programme with no major issues, completing 62 laps over the day.

Adrian Sutil: Today went OK with no major problems, just working through everything as usual with the tyre comparisons. We didn’t make any real changes on the car over the day as I was quite happy with the balance so we just waited until the grip improved on track and worked through the programme. The weather was a bit crazy and actually I think everyone expected more rain, but it was quite light. In FP2 in particular the track was wet in some places and dry in others so getting the right timing was important. I was quite pleased with the progress we made and I hope we can have a good day tomorrow in qualifying as well.

Tonio Liuzzi: With this unpredictable weather it’s important to be out at exactly the right time to get the best of the track so perhaps the final classifications are not truly representative of the real order right now. We still have to work on the balance as it is not 100% just yet but overall the car is responding well to all the changes we have made. Unfortunately we just got caught in traffic every time we tried to do a good lap time but I’m happy we are going in the right direction for tomorrow. I think we could be in for a good qualifying, particularly if the weather stays so uncertain or if it rains some more as we have been pretty competitive in these types of conditions so far this year.

Dominic Harlow, chief race engineer: A couple of periods of light rain during the practice sessions today meant that our programmes were adjusted slightly to get a proper look at the tyres. It seems to be quite a standard set-up with the medium and super soft, and the car balance is not too far away. It’s very close through the field, I’ve never seen so many positions decided on thousandths, not even hundredths of a second. Qualifying will be about traffic management and timing and it looks like the weather could also play a part.

Toyota

Toyota made a positive start to preparations for the Brazilian Grand Prix, the penultimate race of the 2009 season, at Interlagos in Sao Paulo today. Jarno Trulli, after his second place in the Japanese Grand Prix, was joined by Kamui Kobayashi, deputising for Timo Glock who injured his back at Suzuka. After an installation lap to begin first practice, Kamui left the garage 22 minutes in to complete his first serious laps of Interlagos. His first task was to learn the track having only previously experienced it in video games and on a scooter. He consistently improved his lap times while Jarno evaluated aerodynamic settings until a half-hour rain interruption. Both used the medium compound Bridgestone Potenza tyres throughout and, despite late drizzle, completed a trouble-free session. In afternoon practice they again evaluated set-up changes and carried out comparison runs between the super soft and medium compound tyres while Kamui also continued to familiarise himself with race weekend procedures. Despite grey clouds, the session stayed dry until the last 20 minutes, with Kamui performing commendably and Jarno also showing strong potential for the rest of the weekend.

Jarno Trulli: "Everything went well today and we did our usual Friday testing work. We had some rain in both sessions which makes things a bit harder than normal and particularly in the morning there wasn't much grip. But even though the weather disrupted things for us, we still went through quite a few set-up changes and it feels like we are moving in the right direction. The car seems pretty good on this track and I had no major problems so I hope we can continue this positive progress for the rest of the weekend. After the great result last time in Suzuka I am really motivated to keep up the momentum and I am optimistic we can do that."

Kamui Kobayashi: "It was a a nice experience to be starting a weekend as a Grand Prix driver for the first time. It was also my first time driving in Brazil; I found that the track is good fun for a driver and also very challenging. Our work went well; just the weather wasn't perfect with the showers which meant the track surface was not consistent. That made it difficult to properly judge the set-up and also to fully learn each corner because the conditions were changing during the sessions. In the end I found a good rhythm and the car felt competitive so it was a good day for me. There are still things we can improve and I'll be working hard with my engineers to prepare properly for my first Formula 1 qualifying sessions. I'm really looking forward to it and I'm confident."

Dieter Gass - Chief Engineer Race and Test: "Overall it has been quite a good start to the weekend for us despite the difficult conditions all day. The drizzle in both sessions was not ideal but nevertheless we did pretty much all the work we wanted to; we just had to adapt the programme a bit to account for the weather. The two tyre compounds behaved largely as we expected, with no problems although the option proved to be a little better than we thought over a long run. Especially considering the difficult track conditions, Kamui's performance is even more impressive on a track he hadn't driven before today. We can only be pleased with how he performed. As usual we now have to look carefully at the data and fine-tune the set-up to get the most out of the car for the rest of the weekend."

Toro Rosso

Sebastien Buemi: “I am happy that we seemed quite competitive in the afternoon, after the mechanics did a very good job to rebuild the car after my accident this morning. I came up fast behind Liuzzi, who was going slowly on the racing line and in trying to avoid him, I went over the kerb, lost control and spun. I think we showed good speed, even though this is my first time driving this circuit. Now we have a solid basis on which to improve tomorrow, after studying all the data. Today’s session shows that our pace in Japan was not just a one-off. So, I am quite confident for the rest of the weekend.”

Jaime Alguersuari: “I enjoyed my first day at this circuit, which has a nice mix of high speed and slower corners that make it fun to drive and overall, practice went quite well, even though it was tricky when the track was a bit damp. I am still learning and getting up to speed. There is still room to improve the car set-up, especially on the softer tyre, but it’s already pretty good.”

Williams

Rod Nelson, Chief Operations Engineer: “As usual, we covered our standard Friday programme; looking at car balance, qualifying set-up and some longer race runs with heavier fuel. Obviously, the first session was somewhat upset by the rain. There was more rain in the morning session than we expected and then less than we had anticipated this afternoon, but it didn’t affect us too much.”

Nico Rosberg: “Today was all about tyre testing for qualifying and the race. We know roughly what we will do but it’s not entirely clear for the race; that will depend on how much the track improves. We also spent time looking at our downforce level but it’s always difficult and sometimes you need to compromise because, on the one hand, you want to find the quickest lap possible but, on the other, you need to be careful that people are not able to overtake you on the straight. Set-up wise, we just carried out some fine tuning. I don’t think there’s much to improve on that front for this track. Overall, we’ve had a good day’s work and we are where we need to be.”

Kazuki Nakajima: “The weather was quite tricky today but, fortunately, we still managed to get some running in under dry conditions. We worked through quite a lot of things and we know in which direction we want to head for tomorrow now. Whenever I was out on my new tyres, it started to drizzle so I didn’t get to record a good lap time today.”

Renault

Fernando: “Today wasn’t easy because the weather conditions were changing all the time. That made it difficult to concentrate on the set-up of the car, but in the end we did some good runs with positive results and hopefully tomorrow we can continue this good work. I think that the weather will be the key to this weekend so we need to react quickly to any changes and be flexible. We have a very interesting weekend ahead of us and hopefully we can maximise the work that we do tomorrow morning so that we are in good shape for qualifying.”

Romain: “The day has gone quite well but the weather has been so unpredictable. We still managed to make made good progress and tomorrow morning I will continue working hard to improve my times. This was my first experience of the Interlagos circuit and it’s a great place, although it isn’t easy and the track has lots of uphill and downhill sections which are challenging. Tomorrow I need to continue learning the track as well as completing my preparations for qualifying and the race on Sunday.”

Bob Bell, Team Principal: “Today the whole field was very closely matched and at the end of practice there was only a second covering all the cars. In the afternoon Fernando was fastest and Romain was only half a second down in P11. The major problem today was the lack of grip, which I think everybody suffered with, but overall the balance of our car wasn’t too bad. During the day we made a few changes which brought some good results and we also have a reasonable understanding of the performance of the tyres. So we are in good shape now in terms of knowing what to do for the race, but we still need to find some more grip.”
