Williams: We need to work hard to improve overall grip for the race 23 August, 2013 120 Team and drivers review the first day of free practice for the Belgian Grand Prix at Spa-Francorchamps. Xevi Pujolar, Chief Race Engineer: We had limited running this morning due to the weather as the track was damp but this afternoon we completed our planned programme. We tested some different rear wing levels, worked on mechanical set-up changes and did some long runs on both compound tyres in preparation for the race. During both sessions we worked through some aerodynamic evaluations and will now look at the data to decide which direction to continue for the rest of the weekend and to be best prepared for the changeable conditions forecast for tomorrow’s qualifying session. We still need to work hard to also improve overall grip ready for the race. 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. (Williams F1) Subbed by AJN.
