Circuit: Circuito de Jerez -- 4,423 kms
Driver: Sebastien Buemi
Chassis: STR6 - 02
Best time: 1:21.681, 92 laps
Today, it was Sebastien Buemi's turn to return to the STR6 cockpit for the first time since last week's Valencia test. In the morning, he worked on a tyre comparison, trying the modified Pirelli Medium compound and also for the first time, the Hard. The afternoon programme featured two elements: first of all, some aerodynamic testing and secondly a long run, although the latter was compromised by some red flags and the fact that the car stopped with around ten minutes of the session remaining. By then, Sebastien's lap total had already exceeded that required for a Grand Prix distance.
Sebastien Buemi: "The team has done a good job moving on with the development of the car since I last drove it in Valencia. It is definitely better, although at the moment there is no point in talking about its performance level, as we are still working mainly on understanding everything about it. So I am happy with what we did today, when I also tried the Hard compound Pirelli, which worked well and that means I have now run with all four compounds. We have one more day here, which we will use to work through many other elements."
Sebastien will continue to drive tomorrow, the final day of this test session and, at the moment, the weather forecast is for continued good weather, rather than the rain that had been expected. Will next week's Barcelona test provide an opportunity to evaluate the rain tyres prior to the start of the season?
