Here's what the men in the driving seat had to say following final day of the second pre-season test in Barcelona.
Red Bull's Mark Webber: "Today we got through a lot of stuff! We tested a lot of elements and everything worked well, especially since we had such a big programme. That can mean not a lot of laps and a lot of garage time, but we gathered a lot of good information today and that's a pleasing way to finish the week.
"We have a lot of work to do back in Milton Keynes over the next few days to get the car ready for the next test. We've done well over these two first tests and the feeling is pretty good."
Mercedes' Nico Rosberg: "After our first full test with the F1 W03, I can see that we are making good steps forward. Our test programme went well this week and we have made evident progress each day. In terms of reliability, the car is performing pretty much as we expected which is really important as we can concentrate on improving the performance.
"Of course it's difficult at this stage to predict how we will fare in race conditions against our competitors but overall I'm pleased with the start that we have made. I'm looking forward to the final test next week before the season begins, and continuing our learning with our F1 W03."
Force India's Paul Di Resta: "It was another successful day and a good way to end the week. I had a small trip through the gravel in the morning, but nothing that caused too much of an issue, although we lost half an hour of running.
"The important thing is that we still managed to do our long runs in the afternoon and I could feel the changes we made compared to yesterday. It's given me a good impression of the car's balance and consistency, and we've seen that our long run pace is improving step by step."
Caterham's Heikki Kovalainen: "This is the sort of test you look back on and think we're pleased to have got behind us, but we have still learnt a lot here and have ironed out quite a few issues that could have been more serious later in the season.
"Things haven't exactly gone as we would have liked, but I think we all know where the car can and should be when it gets real in Australia, so now the challenge is to regroup in time for next week and make sure we come back here ready to put in a final week of hard work on track and get back to where we want to be."
Sauber's Kamui Kobayashi: "I'm quite happy. We achieved a very good mileage today. The set up changes we did in the morning meant an improvement in lap times, which, of course, is very positive. There is still a lot of work to do in terms of understanding the car and the different tyre compounds at different fuel levels, but we are working in the right direction. I think it was a good test for us."
Toro Rosso's Jean-Eric Vergne: "I am much more confident in the car now than I was by the end of the Jerez test. We worked on many different aspects of the job and for example, today I had a much better understanding of the pit stops than I did after trying them yesterday for the first time. We did some good work today, acquiring plenty of data and I expect this will help us to improve still further next week."
Williams' Pastor Maldonado: "It has been a positive test for the team. We've had no problems with the car, getting in some good mileage across all four days. We now have a great deal of data to analyse so we will keep pushing to improve our car for the next test. I am looking forward to coming back next week for the final test, and getting back to racing very soon."
