Williams: We were able to get some useful tyre data 28 February, 2013 55 Valtteri Bottas Williams report on the first day of the final week of preseason Formula 1 testing from Circuit de Catalunya in Barcelona. Mike Coughlan, Technical Director: The conditions today made it difficult for us to complete our planned programme, but we were able to get some useful tyre data. It was good mileage for Valtteri, as he was able to try a mix of tyres running from the wet, onto the intermediate and finally onto dry tyres this afternoon. It’s a good grounding for him and he brought the car home safely despite the tricky track conditions. The FW35 has now completed another 85 laps without any issues. Valtteri Bottas: It was a good day overall and we had no problems with the car. It’s a shame we were disrupted a bit by the wet weather, although this did allow us to run on the wet, intermediate and dry tyres. I clocked up a lot of mileage for myself and was able to get more experience driving in difficult conditions. It was cold, wet and windy all day, and particularly slippery on track this morning. The Williams F1 Team will be back on track tomorrow, Friday 1 March, with Pastor Maldonado driving the FW35 for the second day of the test.
