Sebastian Vettel set the pace in practice for the Spanish GP, edging Fernando Alonso and Mark Webber...
Sebastian Vettel: "We have some new parts here but the days of big, big upgrades don't really happen now with the regulations how they are. This afternoon was fairly conclusive, but this morning wasn't really much good with the weather. It's hard to say much about the harder tyre, I think the number of pit stops will be the same here in this race as at the last few."
Mark Webber: "It looks reasonably tight. We couldn't have got more out of it today really, the weather made things a bit tricky, but it was a pretty good day overall. We had a few things to test this morning which we had to move to the afternoon when the weather was better - but it was okay. We still have work to do tonight. It's a nice grand prix to come to - one of the most popular of the year."
Fernando Alonso: "The signs from today are positive, as we were quick in both the morning and afternoon and the car seems to be well balanced on light and heavy fuel loads. But it is always premature to try and draw conclusions on a Friday when everything seems to be going well, because in the past we have seen how our competitors can take off in qualifying. We have a great deal of data to analyse this evening, especially because the rain in the morning meant we had to squeeze almost all our planned programme into the second session when it was dry. The feeling is definitely good and even though we are aware it won't be easy, we are sure we can fight it out with the best. I don't expect any great surprises compared to Bahrain and I think the top group is now defined, with Red Bull, Mercedes, ourselves and Lotus, although we need to see how much McLaren manages to improve, while also keeping an eye on Force India, who have been very strong in qualifying and the race."
Felipe Massa: "Everything went well today, even if this morning's rain reduced the amount of time we had to test everything we had planned for the first session. We began that job as soon as the track dried and then finished it off in the afternoon session, paying maximum attention to the handling of the car on both types of tyre Pirelli has brought on this track, especially the new Hard. Even on the long run, the car seemed competitive and this makes me confident and so I hope we can continue to do well right to the end of the weekend."
Lotus F1:Kimi Raikkonen: "It was a pretty normal Friday. We tried some things on the car, ran with some different tyres and we'll have a look at all the data to see where we think we are. We finished the day not too far off the fastest time, so we can say that the day wasn't a disaster, but for sure there are some things we have to improve with the car which is normal after the first day's running."
Romain Grosjean: "Today was okay. It may not look great on the timesheets, but we didn't finish our lap on the medium tyres as I had to come back in. The circuit isn't an easy one to understand in terms of tyre performance as there is a lot of degradation, and of course this morning the weather conditions made things a bit difficult. We completed a good number of laps to collect as much data as possible, so we'll be working on the set-up this evening where we should be able to take some steps forwards."
Lewis Hamilton: "The team have done a great job to bring our upgrades here this weekend and whilst I could feel the impact immediately, it's difficult to quantify how much of an improvement has been made at this early stage. After the first session this morning, I felt there was some good promise and the car was well-balanced but I was a little less happy in the different conditions this afternoon. We'll keep working on it tonight and see if we can make tomorrow a little better."
Nico Rosberg: "It seems that we are quick again on one lap but we need to focus very much on achieving a good race pace. There is still a lot work to do but in general I felt that we had a good test programme today and learned quite a lot. It's difficult to manage the tyres in these conditions and we have seen a lot of graining today because of the lower temperatures."
