Sebastian Vettel was left twiddling his thumbs today. On standby, in case Mark Webber decided not to overwork his injured leg, the German had nothing to do as our Aussie driver comfortably reeled off 83 laps. This was Mark's first taste of the new car and his first day on track since last year's Brazilian Grand Prix.

"There were a lot of questions going into today and I answered them," said Mark at the end of the day. "From my point of view, it all went better than expected and to do over a race distance on my first day back in the cockpit, with several weeks to go to Melbourne is a good thing."

It was also a good day on the technical front as RB5 ran 100% reliably, with the team working through every point on the job list. With the programme running to plan, the team was able to move on from a basic assessment of the new car, to working on aerodynamics and general set-up.

Seb returns to the cockpit tomorrow.
