Intermittent showers throughout the race put the emphasis on making the right strategic calls as Nico stayed on slick tyres for the first phase, leading the race from lap 3 for 16 laps, before switching to intermediates as the conditions steadily worsened.

Michael Schumacher had an eventful race, coming into the pits a total of four times on his way to a tenth placed finish for the final points scoring position, as he managed his worn intermediate tyres.

After four races as the Formula One calendar returns to Europe, Mercedes GP Petronas are in fourth place in the Constructors' Championship with Nico in second position in the Drivers' Championship.

Ross Brawn: "We had a very good race with Nico today. He drove extremely well in difficult conditions and the team did everything right on the tyre stops, making good strategic decisions. We lost some of our advantage with the safety car which was a shame but overall an excellent day and a great drive from Nico. With Michael, we clearly had a more difficult time but at least we got a point out of it. We have some issues that we need to understand as the deterioration of his tyres and therefore his pace is a problem that we need to resolve before the next race. We haven't quite got the car at the moment but when we do, we know that we can get the job done."

Norbert Haug: "A great result for Nico and everybody at Mercedes GP Petronas today. Well done to all of our team members on the second podium in a row with two third places for Nico and our team. Nico is now second in the points standings after four races and certainly one of the most remarkable drivers of this young season. Congratulations to our friends at Vodafone McLaren Mercedes and to Jenson and Lewis for their one-two result. This was the 70th victory for a car with Mercedes power since Melbourne 1997 here in this important Chinese market for Mercedes-Benz. A special thank you from my side and on behalf of our Board to all of the hard-working guys at Mercedes-Benz High Performance Engines in Brixworth and Stuttgart. A great job from you all! It was not a good race weekend for Michael unfortunately. We will investigate what the problems were and I am convinced we will all see much stronger results from him rather sooner than later."

Fabrice Lom, Renault, Principal Engineer Track Support: I hope people enjoyed the show. I'm sure it was a very good race to watch from the outside, but for us it was bad. We recovered a small amount of points, but it was much less than we expected to get here. The good thing is that the engine behaved correctly in these difficult situations, which is always good. We now just have to focus on the next race; we have three weeks to find more pace and be stronger.

Stefano Domenicali: First of all, I want to compliment the pit stop crew, who did an amazing job today, handling three double stops without making the slightest mistake and also helping the drivers to make up places. As for the strategy choices, especially for the first stop, it's clear from the top four finishers that two drivers made one choice and the other two a different one, which means it is difficult to give an instant assessment of which was the right one. With hindsight, Button's paid off better, but it can also be said that, but for his penalty for a jumped start, Fernando could definitely have fought for the victory. As for the passing move involving Felipe and Fernando, we only saw it afterwards on the television replay and I think it was just a racing incident and there is absolutely no problem between the two drivers: when you are always racing to win, you can have moments like this. There's a slight feeling of regret after these first four rounds of the championship. We have definitely ended up with less than we were capable of, sometimes because of incidents beyond our control and sometimes because of things that were down to us. Having said that, we are still fully in the fight for both titles and that is already very important. Now we must continue to push on the development of the car and its performance, especially in qualifying. Starting in Barcelona, we must get back on the podium and that is completely possible.

Chris Dyer: An extremely difficult race, affected by the changing weather and, in Fernando's case, by the incident at the start. After the start of the race, we opted to go for the intermediates, but the track did not stay wet enough for long and so we had to go back to slicks. Then, when the rain came, we went back to wets and both cars proved to be very competitive and the drivers did the best job possible of managing the tyres, better than many of the others, thus managing to gain some places. After the penalty, Fernando drove a great race, just as the pit stop guys did an exceptional job and very well done to them for that.

Sam Michael, Technical Director: It was disappointing not to score points today with either car. Some of the calls on our pitstops were wrong, some were right, but overall we weren't fast enough and didn't make the right decisions. Rubens made a good start so we have improved in that area since Malaysia. We're now looking ahead to Barcelona to take a step forward with our performance.

Alan Permane, Chief Race Engineer: "What an exciting race and another strong performance from the entire team. Robert drove an excellent race and we can be happy to have picked up some more good points with a strong fifth place finish. It's great to see Vitaly score points today and deliver such a mature drive. In the closing stages he did an excellent job to look after his intermediate tyres and it was very rewarding to see him overtaking much more experienced drivers. However, we're a little disappointed because we were in third and fourth places before the second safety car period. Without that, we could probably have finished on the podium."

Remi Taffin, Head of Engine Operations: "Two cars in the points today and a superb performance from both drivers, especially Vitaly who showed good, consistent pace in very difficult conditions. He also overtook lots of drivers today, including a certain former world champion. Robert drove another faultless race and has scored some more important points. As a team there were no problems during the race, which went very smoothly, and we can be pleased to have maximised our potential to come away with fifth and seventh places."

Dr Vijay Mallya, chairman and team principal: It is disappointing to see our run of points end and not to have been able to make more of these conditions, but that's sometimes what happens in this type of conditions: it can become a bit of a lottery. There are still some positives from the weekend - Adrian again proved his wet weather prowess and also that we are genuine top ten. We've got some work to do now that Renault has opened up a sizeable advantage but we have some developments in the pipeline and the season has a long way to run. We'll regroup and come back strongly in Spain I'm sure.

Mike Gascoyne, Chief Technical Officer: "Whilst I'm obviously pleased I want to say first how disappointed I am for Jarno. He's had a lot of bad luck so far - it seems all our bad luck has been on his car, so apologies to him, but it was a fantastic race from Heikki. We judged all the calls correctly and were on the right tyres all the way through, so congratulations to the whole team for that. I'm also very pleased to see our race pace was very good, especially at the end on the wet conditions. These first four races were always going to be tough, but we've achieved what we set out to and now we're looking ahead to Barcelona and seeing how the updates we've been working on help us move forward."

Tony Fernandes, Team Principal: "I'm really happy today as we've accomplished what we said we'd do. We wanted to see at least one car cross the line for the first four races, and we've done that, but it's kind of bitter sweet today. It's obviously a great result for Heikki but a real shame for Jarno as he seems to take the brunt of the issues - it's a bit odd as it does seem to be just his car. The conditions today made it very tense out there and it's very satisfying, and shows how we're progressing, that today we were racing Williams, who we beat on track."

"Another great thing for me was to see how the Lotus Racing dream is spreading, in China, Asia and across the world. We saw a load of Lotus Racing flags in the stands, and this time next year let's hope we see even more fans out there cheering for us - we'll do our best to give them something to be very proud of!"

It was a wet race where many drivers came unstuck and retired in the rain, but both HRT F1 drivers kept control to bring their cars home in competitive positions.

Dr. Colin Kolles, Team Principal: "A good day for the team completing our second two-car finish in the rain in our fourth race. Karun Chandhok and Bruno Senna drove their second wet race after Australia. Again we reached our goal with two cars finishing the race and we gathered quite a lot of data on this track that can be used for the European season. Congratulations to the team. Now in the three weeks to come, we must work on more developments for the team's home Grand Prix in Barcelona."

James Key, Technical Director: "Obviously it was a very exciting race today for watching, but frustrating for us. Kamui was unfortunately the victim of an accident that was happening behind him, and was caught out by a car coming across the track. It was not his fault. Pedro was driving an excellent race, he made a great call on the tyres and the team went with that decision. He stayed on the dry option tyres while others changed to wets, which was a very good call by the driver and the team. He ended up fourth - looked fairly strong, was battling with Vitaly Petrov and the lap times were good. Sadly there was a problem with the car. It is engine related but we can't say whether it's a specific engine problem or a problem related to the chassis. We still need to analyse that when the car comes back. It was a points' opportunity today, but unfortunately it didn't happen."

The final hours leading up to the Race revealed a problem with the clutch on Lucas' car when it was started following release from Parc Ferme. Despite the strenuous efforts of his crew, Lucas was unable to make it to the Grid and the team began to prepare for a Pit Lane start for his car. However, the replacement clutch was not functioning correctly and the Race began without him. Still determined to be part of it in order to gather vital data for the development programme, the team pressed on in the garage and Lucas finally joined the action on Lap 7. Unfortunately, it wasn't long before the clutch problem called time on his race, just 8 laps later.

Everything was running smoothly for Timo until the final stages of the Grid procedure. His car suddenly lost engine valve system air pressure and the team returned the car to the garage to try to fix the problem. It soon became apparent that the issue lay deep in the system and any attempt at addressing it would have called for the entire back end of the car to be removed - a task too substantial to contemplate during the Race.

Both Virgin Racing cars ran faultlessly throughout all three Free Practice sessions and Qualifying, which is what makes today's problems as surprising as they are frustrating.

Nick Wirth, Technical Director: Following the overnight Parc Ferme, we started the cars this morning and discovered that the clutch on Lucas' car was not functioning correctly. We changed the clutch before the Race, but it still wasn't working properly even when we eventually got Lucas out and into the Race and ultimately we had to retire him. Timo's car lost engine valve system air pressure on the Grid, which required us to move him back to the garage. We attempted to refill the air system but it was clear that there was a substantial air leak from the system in a place which was difficult to access quickly, so we were also forced to retire his car. All in all, a very disappointing day, but I know that we will get to grips with the problems and bounce back in Barcelona.

Button led his team-mate Lewis Hamilton across the line by 1.5 seconds. He started on the soft dry compound, before using two sets of intermediates to take him to the chequered flag. Hamilton made four stops, using a soft-intermediate-hard-intermediate-intermediate tyre strategy. Mercedes GP Petronas F1 Team driver Nico Rosberg finished third.

Hiroshi Yasukawa - Director of Bridgestone Motorsport: "Congratulations to Jenson Button for his second win this season and Vodafone McLaren Mercedes for their 1-2. This race was very well supported by Bridgestone China who had many guests present. We were all rewarded with a fantastic battle on track which was enjoyed by all of our guests. Today highlighted the qualities of our dry and intermediate tyres. We are pleased to support such an exciting race."

Hirohide Hamashima - Bridgestone Director of Motorsport Tyre Development: "Today was a fascinating and thrilling race. Fascinating, because conditions were right on the cross-over between the dry and intermediate tyre for so many laps, and thrilling for the action this caused on track. Jenson Button drove very intelligently to take his second win of the season by remaining on the soft tyre when many changed to intermediates, and making good use of his track position from there. There were many different approaches today. The soft compound worked very well in the damp conditions and we are happy with the performance of the intermediate. Both tyres required careful management and Formula One was gifted with a superb spectacle in Shanghai. Now the next challenge for many of our staff is finding a way back to Europe."
