Thierry Salvi, Renault: "Daniel confirmed he was the quickest car behind Mercedes this weekend. He managed his race perfectly, just the same as he did during qualifying. Giving the team a podium is a good gift this weekend. For Seb, it was a great recovery drive and he was flat out throughout the race. His strategy allowed him to ramp up to fourth place: a fantastic result looking at his weekend as a whole - he didn't run on Friday, so was not able to test and set up his car, then FP3 was very busy and again an issue in qualifying. Today's result was the best possible for him in these situations so he showed again how strong he can be in these tricky situations."

Mercedes AMG Petronas took the first one-two finish for a team at the Spanish Grand Prix since 2009. Today's result marks a fourth consecutive one-two finish for the team; a feat last achieved by Mercedes-Benz in 1955. Lewis began the race on option tyres, stopping for a second set of options on lap 18 and primes on lap 43. Nico also started on options, switching to primes on lap 21 and then back to options on lap 45.

Toto Wolff: That was a fantastic afternoon of sport. We have two incredible drivers who are capable of fighting until the last corner of the last lap to achieve success. That was the case again today and they were incredibly closely matched in spite of running different strategies in the race. Their battle is so intense and so close that I am sure it will carry on all the way to the final race. We will savour this victory tonight and enjoy our success - but from tomorrow, our focus is on Monaco. We had a very strong result there last year and our target will be to improve on that this year.

Paddy Lowe: Both cars made a great start and got through Turn One cleanly without incident. From then on, it was all about some incredibly close racing between two drivers, with an hour and a half of constant work between them and their engineers to try and find any possible edge. It's great to watch both sides of the garage working so well to get the best for their driver. Lewis and Nico both delivered great drives and to see a gap of 0.6s after 66 laps of flat out racing just about sums it up. I would like to thank all the team in Brackley, Brixworth and Stuttgart for the huge effort that went into creating such a competitive car at this pivotal and very difficult race of the season. We are now looking forward to Monaco which brings some very different challenges for us to tackle.

Romain started from fifth position on scrubbed medium tyres, changing to scrubbed medium tyres on lap 15, and making his final pitstop on lap 34 for scrubbed hard tyres. Pastor started from the back of the grid (22nd) on new medium tyres, changing to new medium tyres on lap 15, which included his five second stop/go penalty, and stopping again on lap 37 for new hard tyres.

Federico Gastaldi, Deputy Team Principal: "We are very pleased for the team and for Romain to have scored our first points today. It's certainly been a long road to get to this place. It's not all a sweet taste as we were expecting to have finished further up the grid. We had some issues with the power unit again so we need to keep working with Renault Sport F1 to ensure we can keep fighting for as many points as possible. We have two days of testing coming up and our target is to carry on making improvements in performance and reliability."

Alan Permane, Trackside Operations Director: "We're obviously very happy to score our first points of the season and we were enjoying a very good first stint in front of both Ferraris but unfortunately Romain's power unit developed a problem which cost him a step in power for the rest of the race. Given the circumstances, Romain did an incredible job, battling right to the chequered flag. We always knew Pastor would have a difficult race from the back of the grid but he did everything he could to make seven places to finish in fifteenth. We have plenty more in terms of development for the car which we hope to harness with improved reliability."

Simon Rebreyend, Renault Sport F1 track support leader: "It is very positive to score the first points of the season. It shows the rapid progress we have made as a team. Unfortunately Romain was not able to hold off the Ferraris as a calibration issue caused a loss of power from the first part of the race - we need to look at what we can do to correct this in future races. Pastor's race was always going to be hard but we made the best of a bad situation and at least we showed both cars have the pace to be in the top ten."

After yesterday's qualifying problem, Kevin started an unrepresentative 14th, but made a strong start, and battled alongside Jenson for much of the first lap before running wide at Turn 13. He then tapped Sebastian Vettel as the pair entered Turn 14, which dropped him to 15th. Like Jenson, though, he went on to drive a hard, committed race, closing the gap to his team-mate throughout the final stint to finish 12th.

At the chequered flag, the pair was separated by just 0.657s - a strong indication that each got the maximum from his car this afternoon.

Eric Boullier, Racing Director: "Yesterday, our qualifying form showed that we'd taken a small step forwards in terms of performance, although that increment was somewhat disguised by the power-unit issue that prevented Kevin from setting a time in Q2.

"Today, we were unable to translate that small step into points-scoring form, largely as a result of the fact that Jenson lost a few places on lap one and Kevin had started from P14 through no fault of his own.

"Their lap-one scrap was combative but clean, and after that they both drove very well in difficult circumstances, Kevin eventually crossing the line in Jenson's wheel-tracks, less than a second behind, after an excellent and spirited drive.

"Next week Jenson and Stoffel [Vandoorne] will conduct a two-day test for us here in Barcelona, during which we hope to build on the small step we've taken recently.

"We know our journey to full competitiveness won't be a short one, but it's already clear that the trend is in the right direction."

Vijay Mallya, Team Principal and Managing Director: "There were few surprises in this afternoon's race and our final result of ninth and tenth is a fair reflection of the pace we have shown during this weekend. As I said yesterday, this circuit was never going to play to our strengths and yet we still managed to secure a double points finish. It means we've scored points in every race so far this year and this keeps up our momentum in the championship. Like everyone, we suffered with high tyre degradation and it was tricky to make the right decisions on when to stop. We felt we were quite aggressive with both car strategies, but in hindsight we probably could have pushed the limits even more. We now head to Monaco with 57 points and sitting in a strong fourth place in the championship."

Monisha Kaltenborn, Team Principal: "This result is obviously not satisfactory. We came to Barcelona with a development package, and we can see that the gap to our direct competitors is smaller than before. Now it's about further optimising this package. There are still a number of points which are not as good as they could be. On top of that, we have to get a more profound understanding of how to best use the tyres."

Giampaolo Dall'Ara, Head of Track Engineering: "For sure, this result is not great. Nevertheless, the gap to some of our direct competitors' lap times was about half a second, while in the past it was over a second, and this is motivating. So from a performance point of view we were closer, but not close enough. Initially we planned a two stop strategy with both cars, but then we switched to three for Esteban. The car's balance was not as good as it should be, but I guess we know what we have to do, and we will have the chance to work on this during the test on Tuesday and Wednesday. We have a number of new parts which should allow us to get more out of the package."

Ricardo Penteado (Renault Sport F1 track support leader): "It was a hard race all round as Daniil struggled to get the pace from the car, while JEV started with a known issue with his exhaust. We hoped to get to the end but the team decided to retire when the numbers showed it would not be safe to do so. Although the overall result is disappointing we have made progress in energy and fuel management with the new software improvements and the next round will come very shortly in Monaco."

Rob Smedley, Head of Performance Engineering: The car was the third quickest yesterday, as it was today, so overall we are pleased to be there. We came here with an upgrade package and it's clearly worked. Valtteri did a good job to make a two-stop work. We tried a different strategy with Felipe to try and release him, but unfortunately his race didn't quite work out, so we all need to look into every aspect to make sure we are in the best shape with Felipe for Monaco. We are very positive for the future though.

The pair ended the 66 lap race in 18th and 19th places respectively, displacing the single remaining Caterham car along the way and matching the Sauber team - and in the latter stages of the race, Force India - for pace.

The Marussia F1 Team continues to hold 10th place in the Constructors' Championship and Max Chilton's record remains intact, having seen the chequered flag on 24 occasions in 24 races.

John Booth, Team Principal: "Overall a good race for the Team today and one where it's great to be back looking forward to our next set of competitors, as opposed to the cars behind. We planned for a two-stop strategy and after a good start by both cars Jules was away working to build the gap to the cars behind. Unfortunately Max got stuck behind Kobayashi in the first stint and in order to try to leapfrog him, we decided to try a three-stop race with Max. In the end, Jules' two-stop strategy worked pretty much as planned and his pace at the end of the race on the prime tyre was very good. It is clear however that we need a few more tenths for us to stay with the back of the midfield pack. The three stop approach for Max was not as effective as the two-stop but it did achieve the objective in respect of Kobayashi. Unfortunately he ended up behind Ericsson on one of his middle stints, which ultimately meant that the gap to Jules at the end of the race was bigger than it should have been. We move on from this race to the test this week. Through most of the weekend we have been identifying areas where we can see room for improvement and we are pleased that the test will provide us with the opportunity for both drivers to explore these set-ups and hopefully pull a few more tenths out of this package. This will make a huge difference going forwards."

Claudio Albertini, Head of Customer Teams Power Unit Operations, Scuderia Ferrari: "The start of the European season coincided with a particularly challenging race weekend, especially in terms of reliability. Therefore, the outcome of the Spanish Grand Prix has to be welcomed, considering that both Jules and Max once again saw the chequered flag. In terms of performance, there was a step forward, evidenced by the difference in performance compared to our main opponents, but it is clear that there is much work to be done and, on this front, we know that the contribution we can make is very significant. Each kilometre is important to gain experience for the development of the power unit and, in this sense, the two days of testing that will take place at this track next week will be a big help. Our goal is to put the team in a position to be competitive against those teams ahead, albeit everyone is developing at the same time."

Tyre strategy was instrumental to the Spanish Grand Prix, with Mercedes driver Lewis Hamilton claiming his fourth consecutive win to move into the lead of the drivers championship. The Englishman, who went on a medium-medium-hard strategy from pole, beat his team mate Nico Rosberg by just six tenths of a second, who chose a medium-hard-medium strategy. The two strategies ensured a thrilling wheel-to-wheel battle as Rosberg was able to take advantage of his newer and faster tyres at the end of the race.

Red Bull's Sebastian Vettel started from 15th on the grid but finished fourth with a three-stop sprint strategy, running mostly on the faster medium tyre and setting fastest lap. He was also able to make up several places in the closing stages.

The second two-day in-season test of the year now takes place after the Spanish Grand Prix, from Tuesday. Sauber and Toro Rosso will be testing 2015 tyres for Pirelli on the opening day of the test, followed by Force India and McLaren on day two.

Paul Hembery: "We saw some very exciting battles all the way down the top 10 in the closing stages of the race, despite many of the drivers having chosen very different strategies. This underlines the importance of strategy in every race this year, with not just the number of stops but also the order in which the tyres are used really making a difference. Following some overnight rain, ambient and track temperatures were cooler today, and this reduced the time difference between the hard and medium compounds: adding another factor into the equation. Although Barcelona is one of the most demanding circuits of the year, tyre wear and degradation was fully under control, as proved by the fact that the majority of drivers completed just two pit stops. That's down to the hard work of all our team in Milan and Izmit since last year, so a big thank you to all of them. Now we focus on the second in-season test of the year, where we will be developing tyres for 2015."
