Red Bull made a quiet start to proceedings at Hockenheim after mixed conditions of the first day of running ahead of the German Grand Prix.
Sebastian Vettel was twelfth quickest and fastest of the two Red Bull men in the two sessions, which were hit by rain as the day wore on.
The defending champion admitted that there was only so much to be learnt from the action on track with the team limiting its running to ensure it has plenty of wet tyres for the remainder of the weekend.
“We couldn't learn too much today, so we just got used to the conditions, as there may be rain tomorrow and also on Sunday,” he said. “The forecast isn't looking great. It would have been good to have got some dry running in, especially this afternoon to test a couple of things and see how the car feels – it's hard to get a proper baseline when the conditions keep changing. We have to carry the extremes into tomorrow and Sunday, so we obviously tried to limit the running on those tyres.”
Team-mate Mark Webber was down in 20th on the timesheets and the Australian admitted that conditions on track had been worse than the team had expected them to be.
“That was a bit unreal,” he said. “We didn't expect the rain to be this bad today, but it was quite heavy at times – we even used the extreme full wet tyre. That's two races in a row now with tricky conditions. We haven't done much dry running yet, but Sunday looks like it will be better weather-wise.
“We needed to check what the track conditions were like in terms of grip level, as it's a different layout here to Silverstone and different asphalt. We tried a few small new parts today. The lap times were all over the place and there were a few incidents, but we got everything we could out of that session.”
