Norbert Haug - vice-president, Mercedes-Benz Motorsport: "A race like a battle. Despite starting from the sixth row on the grid, Lewis was in good shape - and everybody who kept his car on the track in these conditions was a hero today. Congratulations to Jenson Button and Brawn GP on the second consecutive win with Mercedes power; which he both achieved from pole position."

Stefano Domenicali: We are very disappointed because once again today, we leave a circuit empty handed. With hindsight, it's clear that we took some wrong decisions, especially in Kimi's case at his first pit stop: the information we had at the time was that the storm was due to hit in a very short time, when in fact it took a few more minutes for the rain to come. Felipe was very unlucky: another forty seconds or so and he could have stayed on track with the extreme wet tyres, finishing in a good position at the end of the race. Clearly we have to extricate ourselves from this situation, without panicking, but with every one of us taking on our responsibilities: we have to dig deep and react, starting immediately. We have to change our mentality and accept that we are in a different situation to the past and that therefore we have to tackle it with a different approach, both on track and in Maranello.

Luca Baldisserri: Another disastrous race, and we can't make any excuses for it. Once again today we tried to second guess what might happen and every time the opposite of what we expected happened and so the race was turned into a continual struggle to make up for that and in the end we finished empty handed. In the dry, our race pace was not really exceptional, but it did reflect what was our true potential today. Now we must try to turn things around and get out of this situation in a hurry.

Mario Theissen (BMW Motorsport Director): "The race was as chaotic as we expected based on the weather forecast. For Robert, the race was already over at the start because his engine didn't respond to the throttle. According to an early analysis the reason was a leakage in the pneumatic system. Because of the weather forecast we put Nick on a heave fuel load. This enabled him to stay out until the rain started. He switched to rain tyres at the right moment and was able to finish the race. In extremely difficult conditions he managed to achieve the best possible result. Compliments go to Nick and the whole crew, who worked without any mistakes."

Willy Rampf (Head of Engineering): "This was not a race for poor nerves! For Robert, the GP was over at the start. That's a shame, because he was in a strong position. Nick started on a heavy fuel load. The strategy to leave him out for a long time paid off. This was brave, but in the end it worked out. In very difficult conditions he managed to keep the car on the track and to capture a podium finish. Compliments are due to the whole team who worked perfectly in chaotic conditions."

Pat Symonds, Executive Director of Engineering: "I suppose in many ways the heavy rain is no surprise to anyone who knows the area, but it brought some interesting elements to the race. In the early part of the race the value of the KERS system certainly showed, but as in Australia we still need to find performance from the car in other areas."

Remi Taffin, Head of Engine Operations: "Today we are disappointed. The race was challenging and we tried our best to adapt, but the weather was so difficult to predict. We knew it was going to rain, but we didn't think it would be so heavy. However, I didn't expect the race to be stopped. We now have to work hard, but I feel we have taken a step forward since Melbourne, as shown by our strong start to the race."

Tadashi Yamashina - Team Principal: "I am very proud of the team's efforts today because it is fantastic to get another podium and it shows how competitive we are this season. It was an extremely challenging race for the team but everyone did their best and was professional even in those difficult conditions. It is disappointing for the fans that the race could not continue as scheduled due to the weather but there was nothing that could be done. We have shown again today that we are really fighting at the front this season and I am obviously hoping we can continue this very good performance in the Chinese Grand Prix as well."

Fabrice Lom, Renault, Principal Engineer, Track Support: What a race! We had a difficult start at the beginning and Mark lost some places, although Sebastian made some. Both cars then had good fights– moving up through the field and overtaking lots of cars. Then the rain came and it was like a lottery. We have to apologise to Sebastian; the anti-stall didn't catch his engine, so we have to investigate that. Mark did a fantastic job; it's an unfair result for him, but at least we get the first points of the year.

Sam Michael, Technical Director: It was a great start from Nico and he continued a good performance in the dry in the first stint. When the weather came, we made the same tyre choices as the cars around us, including the Brawns and Trulli, but they gained more from their stops than us.

The race had started under ominously cloudy skies, but conditions were dry until 30 minutes into the event. Banking that the typical heavy rain would be imminent, both Giancarlo and Adrian pitted for extreme wet tyres. The downpour did not materialise however for a further 30 minutes, and when Giancarlo was just returning to the pits to change for another set of wets he aquaplaned off the circuit. Adrian did however change tyres but was in the pits when the race was suspended.

The team will now return to its UK base for a brief halt before resuming its 2009 campaign in China in two weeks.

Dr Vijay Mallya, chairman and team principal: 'Today in Malaysia we had almost unprecedented conditions and we took a risk with the strategy. Unfortunately the rain we expected - which you can normally bank on coming - didn't come soon enough and Giancarlo was unfortunate enough to be returning to the pits for a new set of extreme tyres when the rain hit hardest. As a team we will learn from this as we move forward to China and Bahrain. We're growing in confidence and potential all the time so we just need a good race to demonstrate it.'

Jenson had a good start from pole but was unable to prevent the cars on the other side of the grid overtaking down into the first corner and was running third by the end of lap one. He took full advantage of his heavier fuel load to put in some quick laps when the cars ahead pitted and took the lead on emerging from his first pit stop on lap 19. Rubens had a good start from eighth on the grid, battling through to make up six places and to be running in second position by his first stop on lap 20.

The race became increasingly hectic as rain threatened and the field dived into the pits. Jenson and Rubens pitted on lap 22 for wet tyres but the downpour was less than expected and they came back in for intermediates on lap 28 for Rubens and lap 29 for Jenson.

When the rain did arrive, it was so torrential that the wet weather tyres which the drivers fitted on lap 31 were not enough to allow the race to safely continue. After a lengthy delay on the grid, the race was declared over and half-points awarded.

After two rounds, Brawn GP lead the Constructors' Championship with 25 points and Jenson leads the Drivers' Championship with 15 points with Rubens in second position with 10 points.

Ross Brawn: "A fantastic team performance today and a thoroughly deserved second victory of the season for Jenson and the team. It was an eventful race to say the least and I am pleased with how quickly we were able to react to the changing conditions to maintain the lead that Jenson had achieved in the first stint of the race. However it was not perfect as we could have had both cars in the top three if we had been a little bolder in bringing the drivers in for their third stops for intermediate tyres. We are delighted to have had such a successful start to the season with two pole positions and two victories in the opening races. You can't ask for more than that and it is a credit to the talent, attitude and dedication of our team that we have been able to achieve such results."

Black clouds provided a backdrop to the start of the race, but it was Bridgestone's black rubber which provided the crucial performance variable. Once the rain started, the water levels on track changed lap by lap making it very difficult for competitors to choose whether the dry slick, intermediate or wet tyre should be used, and the best tyre for the conditions changed frequently.

As the race was stopped before three-quarter distance, only half points will be awarded. Nick Heidfeld (BMW Sauber) took second and Timo Glock (Panasonic Toyota Racing) finished third.

How was the race from Bridgestone's perspective?
Hirohide Hamashima - Bridgestone Director of Motorsport Tyre Development: "This was a very interesting race, even before the rain started. Everyone started on the soft tyre. The soft gave good consistent performance in the conditions we saw today and there would have been good strategy options had the weather remained dry Starting on the soft was a sensible move as the soft has a lower working range than the hard, so when the rain started it delivered better performance than the hard would have done, before the wet tyres became necessary."

How important was tyre strategy?
HH: "Choosing the correct tyre at the correct time is absolutely crucial and we saw many illustrations of how beneficial it is to make the right choice. Once the rain started there was a window where the intermediate tyre was the best one to use, as shown by Timo Glock who was up to ten seconds faster than the other cars. Some drivers used the wet tyre too early, and suffered in the too dry conditions. However, once the rain became harder the wet tyre was the correct tyre for conditions. Unfortunately, the rain then became so hard that it was too wet for Formula One cars."
