Mark Webber got back behind the wheel of the RB9 in Barcelona, taking over testing duties from teammate Sebastian Vettel. The long runs of Thursday meant pace wasn't top of the agenda for the Red Bull team, and that was represented in their ninth fastest time at day's end.
As Webber explains, testing times aren't at all telling: "As usual at tests, the question of the pecking order comes up all the time but, honestly, I have no idea. There are a few quick cars out there, but in winter testing it’s so hard to say if anyone’s better than anyone else, especially with the tyres going off the way they are – you’re losing four or five seconds over the course of a stint, so figuring out who’s doing what is pretty difficult."
The Australian also added that they may not be able to complete the programme they're hoping for, saying: "We’d like to get a bit more mileage tomorrow in the dry, but that doesn’t look like it’s going to happen, it looks like it will be wet."
