Cyril Dumont, Renault: "Unfortunately for us, today is a race to forget. There is already a lot of gambling when you have these conditions and if you add the issues we had - which was no radio communication with Seb for most of the race and with Mark for parts of it - then it made it even more difficult. The race was going okay until Seb had the incident with HRT which caused a problem with the left hand wheel. For Mark fourth place was not too bad, but we would have preferred for him to have been on the podium. We have two weeks away from racing now and will be pushing to get back to where we need to be."

"For Jenson, it was simply a bad day in the office - losing a front wing in tricky conditions was always going to make it a hard afternoon for him.

"Lewis was somewhat unlucky, too: Ferrari's 'double-shuffle' pitstop meant we were obliged to hold Lewis in his pitbox longer than we would have liked, but that's motor racing. Nevertheless, he brought home some extremely valuable world championship points - his 15 points today consolidate Vodafone McLaren Mercedes' position at the top of the constructors' championship.

"Today's conditions were always going to represent something of a roll of the dice. We didn't quite manage everything today, and we'll go back and analyse our performance, but in normal dry conditions we've shown that we've got decent pace. There's a long season ahead, and with one victory and two strong podium positions, we can return to Europe extremely encouraged about the forthcoming races."

Stefano Domenicali: An incredible win, absolutely unexpected, but that does not make it any less wonderful and emotional! Once again, Fernando was amazing, driving with a cool head and determination, managing to get the very best out of this car and of the very changeable weather conditions. Today's victory does not change a jot in terms of our situation: we know that, at the moment, we do not have a car competitive enough to fight for the win under normal conditions and that we have a lot of work to do to catch up. Clearly this win gives us even more motivation, because it shows that this championship is not at all clear cut and anything can happen. A slight improvement in performance can result in a good step forward compared to other teams. Felipe suffered too much with degradation on his front tyres, which led to him making one more stop than his team-mate: this is a particularly difficult moment for him, because he cannot get the most out of a car that, objectively, is very difficult to drive. We have an obligation to stay close to him, which is as it should be in such a closely knit team. Now we will enjoy this moment for a few hours, but tomorrow we must be back in the factory again pushing on the development of this F2012. Finally I want to congratulate Sauber, who today secured their best ever result and congratulations also to Sergio Perez, a youngster from the Ferrari Driver Academy, who today confirmed his great talent.

Pat Fry: This win is a wonderful reward for all the efforts we are making here at the track and back home at the factory to try and turn around a season that immediately saw us facing an uphill struggle. However, this result must not be seen as a case of all our problems having unexpectedly solved themselves: that's not the case and everyone is aware of it. Fernando drove a fantastic race, pushing throughout the entire time, always being very careful but never overdoing it. The F2012 seemed to behave very differently depending on the conditions in which it was running: today, there were moments when it was absolutely competitive, others when it struggled. We had already seen in Melbourne on Friday that on a damp track, the situation was not bad and today it went even better. Towards the end, Perez was very quick, partly because his Hards were working better in these conditions than Fernando's mediums. Another decisive factor in today's win was the work in the pits and on the pit wall: at every pit stop, Fernando managed either to make up places or to stay ahead of his pursuers. Felipe made a good start but suffered quite badly with the front tyres as the track was drying. We tried to remedy the situation, bringing him for an extra stop and clearly that cost him valuable time. We must try and understand why, for him, the car ends up being even more unstable in terms of its handling compared to the way it works for his team-mate: it is one of our tasks for these coming days along with obviously trying to find the tenths in performance terms that we are still lacking.

Starting from third, Michael's car was touched on the first lap leading to a spin which dropped him to 16th at the end of lap one. The rain falling prior to the race increased in intensity from lap four and led to a red flag on lap nine and a 51 minute delay. After the restart, both Michael and Nico struggled to get the best from their tyres and were not able to fight for positions. Michael stopped on laps 5, 14 and 39, with an intermediate/wet/intermediate/prime tyre usage. Nico stopped on laps 5, 13, 26 and 39, with an intermediate/wet/intermediate/intermediate/prime tyre usage.

Ross Brawn: "It's a very disappointing end to what had been such a positive weekend here in Malaysia. Clearly we have a conundrum with this car that we have to unravel. After such an encouraging qualifying session, and indeed the fuel runs that we did on Friday, we struggled to get the tyres to work properly in the race today. There were little windows when we seemed to get them working and other times where we fell out of them completely. I don't believe that we are abusing the tyres, just not using them properly, and it's a problem that we have to solve if we are going to move forward with the car. It is especially disappointing after the potential we have shown, however I am confident that we have enough strength and the right people to unravel the problem. We will be getting our heads down back at the factory next week and doing just that."

Norbert Haug: "From P3 Michael did not have the best start but was still in a top five slot when he was spun around during the first lap and passed the start and finish line in P16. After the restart, things did not go any better and we never really could cope with the wet conditions and the drying out track on which nobody has had the opportunity to test before the race. Other teams could obviously handle these mixed conditions better and all credit to them. Both Ferrari and Sauber did a great job today so congratulations to those teams, Fernando Alonso and Sergio Perez. We obviously did not have the set-up to make the best out of these tricky conditions today. We brought Nico in and put him on slicks which was a calculated risk that finally did not pay off. Our car has got speed and we will continue to work hard to generate this speed in the race as well as in qualifying."

Both cars started on the green marked intermediate tyres. Kimi made three stops with an intermediate, wet, intermediate, hard tyre strategy. Kimi set a succession of fastest laps on the hard tyres as the track dried, culminating with a 1min 40.722secs on lap 53. It was the 36th Grand Prix fastest lap of his career.

Eric Boullier, Team Principal: "Today's result is a bit frustrating. Whilst it's good to have a car finish in the top five after starting from tenth in conditions which were very tricky, we can't help thinking that we could have achieved more from this race. Obviously, it's disappointing for Romain, as it's another DNF for him in the early laps of the race. He had never driven in the rain with these intermediate tyres so we have to take that into account. He had a very good start off the line, but the contact with Michael ruined his race. At the restart, we recovered well from our position and on the plus side, the car looked strong again. Kimi had a flawless race. He was very consistent in all conditions and his best lap shows what could have been without his grid penalty. I'm sure when we have a 'standard' weekend - without bad weather, penalty or interruption - we will do very well."

James Allison, Technical Director: "What we would give for a normal race! We had to fight back from a grid penalty for changing the gearbox on Kimi's car. We also had two drivers learning Pirelli's wet tyres for the first time today. This made for a difficult time here at Sepang. Our pace at the end of the race on dry tyres looks extremely promising from the perspective of both degradation and pace. Give us a normal race, with two clean getaways from the good qualifying positions of which we have shown we are capable, and I think we'll be able to collect a good reward."

Ricardo Penteado, Renault Sport F1 Team Support Leader: "Another points scoring finish for Kimi here. Again it was a shame for Romain but over the course of the weekend we confirmed the pace seen in Australia of the Lotus-Renault package. The changeable weather made it very difficult to manage fuel consumption. We burned a lot of fuel at the second start, which allowed us to be lighter towards the final laps. This played out well as Kimi set the fastest lap of the race on lap 53. Overall the engine has worked perfectly and we're now looking forward to China, which presents a very different challenge."

Robert Fernley, Deputy Team Principal: "Today's result is thanks to a tremendous team effort with everybody rising to the challenges presented by the tricky conditions. It was an especially busy race on the pit wall, but on the whole I think we made the right calls, especially the timing of our switch to the dry tyres, and both drivers delivered very strong performances. It was important to pick up points on a day like this and given where we started we have to be happy with eight points. The race was not without drama, though, and Paul was lucky to emerge unscathed from the contact with Maldonado, which occurred in the very wet conditions. Both Paul and Nico came on the radio to say how poor the conditions were, and it's to their credit that they managed to stay largely out of trouble. We now head to China determined to carry on this momentum and hopefully add some more points to our tally."

For his team mate, Kamui Kobayashi, the guessing and gambling with the weather conditions didn't pay off that well. The team took different options for the two drivers in order to maximise its chances. Kamui made an excellent start and then had to deal longer with the increasing rain on intermediate tyres. Before his late stop for rain tyres he was running ninth, but for the restart he was then only 16th. Later he retired after 47 laps because of brake problems.

Peter Sauber, Team Principal: "What a great result! Sergio drove an outstanding race and rose above our expectations. What surprised me most was the fact that he was very competitive in all conditions and with all tyres. Whether they were wet, intermediate or dry tyres he was always one of the fastest drivers on track if not the fastest. This obviously also shows the huge potential of the car. And I want to pay a big compliment to Giampaolo Dall'Ara and his team for doing a great job with the strategy. Thanks also to everybody in the factory in Hinwil. I'm sorry for Kamui who had to stop due to a technical problem. Nevertheless it was a great and important day for the team."

Giampaolo Dall'Ara, Head of Track Engineering: "It was a very strong race for our team. We made a good call on the weather conditions, and then Sergio took over. He drove a brilliant race. His pace was excellent on a wet and dry track. For Kamui it was an unlucky race. First we should have called him in earlier, but there was a chance of rain. This judgment was wrong. Secondly he had a leak in the brake system which stopped him, and we are sorry for that. We have to investigate it. However, it was a great performance and a great result for the team."

After beginning under safety car conditions, the race was red flagged on lap nine for just under an hour due to heavy rain. Following a first lap incident, Bruno made an unscheduled pitstop for a new front wing. Pastor had to make an additional pitstop after poor visibility caused him to miss his pit box when attempting to pit for wet tyres on lap 14. Bruno drove a great race to come through from 23rd at the restart to claim eight points. Both drivers put in consistently quick laptimes to challenge for positions throughout the race.

Mark Gillan, Chief Operations Engineer: It was a real rollercoaster of a race and the whole team are delighted to get our first points of the season. Bruno drove very well finishing in sixth, having been last at the restart. Unfortunately we had to retire Pastor with an engine problem with only a few laps left whilst he was running in tenth.

Laurent Debout, Renault Sport F1 team support leader: Our feelings are obviously very mixed. It's very satisfying to score the first points for the new Williams-Renault package with Bruno's sixth position, but very frustrating to lose a potential double points finish due to an engine failure on Pastor's car. We are still looking into the problem but apologies to the team and we'll look to make amends in China. There's a long gap between now and then so we have time to fully investigate.

Mark Smith, Technical Director: "From the technical perspective that was an incredibly busy race. With the constantly changing conditions we had to make a number of calls to give us a chance to fight and while that paid off for Vitaly, for Heikki it was a much tougher afternoon. He had to change a front wing after going off track and that effectively ended his race, but it is good to see how hard Vitaly was able to push, and to see the lap times he was putting in on the inters."

Tony Fernandes, Team Principal: "I'm happy with how the race went today. We recorded our first two car finish at our home race in Malaysia, and we definitely gave the fans here something to cheer for, particularly with Vitaly battling with the likes of Ferrari, Williams and Toro Rosso. We showed good pace and with a bit more work ont he strategies I think we can keep demonstrating that we keep edging ever closer to what is clearly an intense battle in the midfield. The fact we are now fighting with some of the most famous names in motorsport is a huge achievement in what is only our third season, and now we will keep fighting to close that gap which is already so much smaller than it was last year, and streets ahead of where we were in 2010."

Overall it was a satisfying result for the team who now has two weeks ahead to prepare for the Chinese Grand Prix in better conditions.

Luis Perez-Sala, Team Principal: Yesterday after qualifying we were satisfied and today, thankfully, we are again. We met another target which was to finish the race with both cars. There are aspects that need improving, without a doubt, such as reliability and the speed of the car, but by completing the race we have accumulated a lot of data which will be of great use to continue progressing. We also need to improve pit stops and team coordination but it was the first time they did it and from the first stop to the second you could already tell the difference. Today I want to highlight the work everyone did and thank them for their effort these past weeks and today’s result is a small reward for that enormous amount of work that is taking place.

The team enjoyed its second double finish in two season-opening races, with Timo Glock crossing the line at Sepang in 17th place and Charles Pic in 20th, and the Caterham of Heikki Kovalainen providing the meat in the Marussia F1 Team sandwich. The legitimate battle that both of the team's drivers enjoyed with its immediate competitor today underlined that it is back on course and can start pushing ahead in earnest with its development programme.

John Booth, Team Principal: "A fantastic end to what has been an important weekend for the team. It is extremely encouraging that we are seeing progress in every area, the most significant of which is in terms of performance. The small upgrade that we brought on Friday was the result of some very hard work in the factory over the last few weeks by the aerodynamics department and we have certainly seen the benefit of that here this weekend. However, we can't rest on our laurels and this is now the start of what is going to be a very intensive and exciting development programme for us. It was an interesting race today, with plenty of twists and turns to keep us on our toes, which the race team handled admirably. We were particularly impressed with the way Charles held off Kovalainen for so long, losing out only at the pitstop. Equally worthy of note was Timo's performance in the drying conditions, which was superb. We now look forward to evaluating the findings from these two races so we can come back stronger again in China in three weeks' time."

A rain shower before the start of the race meant that all the drivers apart from the two HRTs started on Cinturato Green intermediates. After just one lap, Perez came into the pits to change to full wets as the rain fell harder - and this call turned out to be the foundation of his result.

His early stop meant that Perez was up to third when the race was suspended on lap eight because of torrential rain. The re-start took place behind the safety car, which obliged all the drivers to start on the full wet tyres, according to the rules. As the track dried, the leaders moved onto intermediates and Perez led a race for the first time, before being passed by Alonso.

Even before the red flag came out, there was already variety of tyre strategies in play. HRTs decision to start on the full wet tyre boosted Narain Karthikeyan to 10th overall when the race was suspended: the first time that the young Spanish team has finished a lap in the points. By contrast, Toro Rosso's Jean-Eric Vergne remained on the intermediate tyre until the red flag, proving the adaptability of Pirelli's Cinturato Green by hanging onto seventh place despite huge quantities of spray and standing water. Marussia also found itself running in the points, thanks to eighth place for rookie Charles Pic shortly after the re-start.

On lap 37 Toro Rosso driver Daniel Ricciardo was the first driver to move onto slicks, using the P Zero White medium, while Alonso's switch to the medium slick three laps later was instrumental in ensuring his 28th career victory.

The fastest lap of the race was set on the P Zero Silver hard tyre by Lotus driver Kimi Raikkonen with three laps to go. The longest stints of the race were all 27 laps on the Cinturato Green intermediate tyre, run by Lewis Hamilton (McLaren), Kimi Raikkonen (Lotus) and Kamui Kobayashi (Sauber).

Paul Hembery: "This race had echoes of Canada last year, which was also suspended due to rain. Once more, that created an intriguing set of circumstances and some stand-out performances, such as Alonso and Perez at the front, who were the class of the field. After the re-start, it was important for the drivers to look after the intermediates - which showed great versatility in very mixed conditions - in order to keep them within their operating temperature range. The top two finishers adopted a completely different tyre strategy, with Alonso on the medium tyre and Perez on the hard tyre in the final stint, which shows how our decision to close up the performance gaps between the compounds has led to even closer racing. We'd also like to congratulate Bruno Senna, who scores his best-ever grand prix result in sixth."
