Mark Webber revealed that there were no big surprises as he gave the Red Bull RB9 its track début.
Webber was second fastest in Jerez and completed 73 laps.
"It was pretty good. As Adrian [Newey] said at the launch, there haven’t been big changes to the regulations this year and the car is an evolution of the one we finished with last season, so there were no big surprises. I think most of the drivers will sit back tonight and think today’s times were pretty competitive."
"It was actually like a Friday practice session in some regards. We started understanding the tyres and there were a lot of positives," he added. "There’s a bit of housekeeping we have to get on top of but, other than that, it’s been encouraging. The car feels similar to last year’s, so the main difference is the tyres. With these tyres you’re always on your toes. It was good that we had consistent temperatures today, so we got a lot of information and feedback to analyse, which is all good. Generally though, the car feels pretty good, so I’m happy."
Engineering Co-ordinator Andy Damerum added that the team completed about 90% of what was on their list.
