In contrast to last year, Mark Webber says his Red Bull team is confident before next month's formula one season-opening Australian Grand Prix.
And Red Bull boss Christian Horner says there is now a ''relaxed'' atmosphere within the championship outfit after last week's testing in Spain.
The team was well behind in its development program at last year's Australian Grand Prix, but Webber lauded its mechanics for their latest work.
Red Bull will return to Spain next week for another session, where car performance will be a focus, before travelling to Melbourne.
Formula one teams had to deal with cold and rainy weather at the Catalunya track but Webber and his team managed to complete their full program and after 64 laps he was upbeat.
''The mechanics were incredible in getting through everything. We got a lot of good stuff done,'' Webber said.
''The boys did a great job - the best I've seen them, I think, so all credit to them.''
Webber said the team's ''housekeeping'', including pit stops and other race weekend elements, went off without a hitch.
''We're back here next week and we'll do more of the same for sure,'' he said.
''[We'll look] into how the tyres work, checking how they perform in different temperatures, all of that kind of thing.''
Horner says Red Bull is headed into the 2013 season more relaxed about its chances as it chases its fourth consecutive constructors' and drivers' titles.
''In many respects the pressure is off us because we've achieved a triple double world championship,'' he said. AAP
