Vettel and Buemi at work for Red Bull

Sebastian Vettel took over chassis five from Brendon Hartley today and joined Sebastien Buemi for day two of Red Bull Racings three-day test at Jerez de la Frontera. Running two cars, the team concentrated on making set up changes to improve the balance of the car on the new-for-2009 slick tyres.

Although Vettel ran wide at Turn one a couple of times during the day, there were no significant problems and both drivers completed 83 laps each.

Buemi commented: "It's been a very good test so far, we've been improving with every lap, which is really good for next season and I'm happy. We're learning more about the slick tyres too, which is important. I'm looking forward to tomorrow and trying to improve myself more."
