Farewell 2008 - Today was the final day of testing this year and both Sebs had good days,with Vettel quickest at the end of the session.Both drivers worked on evaluating various mechanical set-up changes in conjunction withthe 2009 specification Bridgestone slick tyres and the team leaves southern Spain withplenty of data and a good understanding of next season's rubber. The RB4s ran completelyreliably all day and overnight work on Vettel's car meant it was more to his liking today.
At the end of the day, Vettel said. "We've had pretty smooth running at this test and havecompleted a lot of mileage before the end of the year. I think we've done everything wecould here, learning about the tyres and next year's regulations and hopefully we will startnext year with a car strong enough to challenge the big boys."
