Williams: We now look forward to the launch of the FW35 8 February, 2013 Valtteri Bottas (FIN) Williams FW34. Williams team report on the fourth and final day of Formula 1 preseason testing at Jerez, in Spain. Mike Coughlan, Technical Director: We have had a very good four days in Jerez running the FW34. We have gone through a complete programme testing various parts that will be used on the FW35. This compliments our current philosophy of using rigs to pass off systems before running them on the car. The drivers have enjoyed themselves running through tyre comparisons and set-up changes that you would be reluctant to do at a race meeting due to time constraints. Although these results have been a little compromised by the very aggressive nature of the track surface here, we have acquired some useful data to carry forward. We now look forward to the next test in Barcelona and the launch of the FW35. Valtteri Bottas: It’s been a good four days of testing for us and I’ve really enjoyed the last two days in particular when I’ve been driving the car. We have achieved everything we planned this week without any issues, and I’ve really liked how the new technical team have been working. We collected some valuable data regarding some parts for the new car and now I’m excited to go to Barcelona to drive the FW35 for the first time. The Williams F1 Team will present its 2013 car, the Williams Renault FW35, on Tuesday 19 February at the Circuit de Catalunya, Barcelona in Spain.
