Vettel and Red Bull tester Sebastien Buemi worked on evaluating various mechanical set-up changes in conjunction with the 2009-specification Bridgestone slick tyres. The RB4s ran reliably all day and overnight work on Vettels car meant it was more to his liking. The German completed 107 laps, the Swiss 92.
“Weve had pretty smooth running at this test and have completed a lot of mileage before the end of the year,” commented Vettel. “I think weve done everything we could here, learning about the tyres and next years regulations and hopefully we will start next year with a car strong enough to challenge the big boys.”
BMW Saubers Christian Klien spent the morning in the teams KERS-equipped F1.08B, working on different energy strategies. "We made good progress today," said the Austrian after 38 laps. "We still have a lot of work to do on the KERS system, but the promising test results show we are moving in the right direction."
In the sister BMW - without KERS - Robert Kubica tried numerous set-up solutions aiming to improve on the results from using the new slick tyres. He switched to the KERS-equipped car in the afternoon, but had to abandon the scheduled programme due to a mechanical failure. He completed 100 laps overall.
The final driver was Kazuki Nakajima, the Japanese driver running a mammoth 131 laps as he wrapped up Williams track work for 2008.
