It was another tardy start to a race weekend for Williams who joined Caterham and Marussia at the bottom of the Spa timesheets...
Pastor Maldonado: "Today I was struggling to get the right balance in the car and there is still a lot of work we need to do to get us to where we want to be. We are not very far from unlocking more speed, but the others around us are also making gains which makes it difficult to close the gap. Nevertheless we will try to optimise what we have and adjust the set-up to find improvements in the balance ahead of the weekend."
Valtteri Bottas: "It was difficult to test anything in the first session because of the variable weather, with the track wet on one part of the circuit but dry on the other. The dry second session was more productive and we conducted some interesting tests so we will now be analysing the data from those to make improvements to the set-up for tomorrow. My car is currently more competitive on the prime tyre, and we still have work to do to improve the overall balance on the option tyre."
Giedo van der Garde: "FP1 was a good start to the weekend. We did the installation lap on wets but for run one we went onto inters but the track was drying out pretty quickly so they didn't last too long at all. It looks like quali and the race could both have similar weather conditions to FP1 so it's good to have that information logged, but then we went onto the hard dry tyres for run two, giving us more information that the engineers can work on tonight.
"In FP2 the weather had improved from the morning session but the car didn't feel great on the first run. We had a lot of oversteer on run one and not great traction so we made a change and went out for run two on the medium tyres. The first run on those was ok but we weren't really able to get everything out of the softer rubber so there's definitely more to come from the softer rubber. On the long run on the mediums the car felt pretty good, deg levels were ok but then in turn 15 the back end got loose and I unfortunately made contact with the barrier ending the session. We're not sure why that happened yet but we'll have a look at the data and investigate more tonight. Hopefully there's a lot more to come, so a usual busy Friday night and I think we can make progress tomorrow."
Charles Pic: "We went straight out in FP2 on the hard tyres and the car was ok but the main issue on run one was mid-to exit oversteer. We made a couple of mechanical changes for the second run but still had the oversteer issue but with more changes it had improved slightly for run three when we put the medium tyres on for the first time. The car was more calm on mid-to-exit but we found we had some issues on entry into the corners so for the long run we put on a bit more front wing and it did feel like we made some progress. We still need to make more improvements to the stability of the car on entry into the corners, but we can look at that more tonight, as well as keeping an eye on the weather forecast for tomorrow and even more for Sunday."
Jules Bianchi: "The summer break seemed like an eternity for me so, on the whole, it is good to be back in the car and to get the second half of the season underway. It has been a little bit of a frustrating day today though, firstly with the weather making it difficult to get into the swing of things, although the experience in the wet may be useful later in the weekend. There is some work to do yet to get the car working better here but on paper this should be a circuit that suits us better than the last few races before the break."
Max Chilton: "I'm pleased with the way things started out for me today and with the progress we were making in FP1. The car was feeling good and the programme was working well. Things were looking promising for FP2 also but unfortunately we lost the last 30 minutes of the session because of a steering rack change. The guys worked hard to ensure I could get out at the end and so let's hope for a more straightforward day tomorrow to pick up on the positives from this morning."
