In contrast to last year, Mark Webber says his Red Bull team are zoning in on a confident start at 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 their mechanics after 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.
"That will be right at the top of the list but also we'll undoubtedly be doing some performance stuff, which you constantly need to keep putting on the car in order to stay close to the front."
Horner says the team is headed into the 2013 season more relaxed about its chances than ever before.
Red Bull will be chasing their fourth constructors' and drivers' titles in succession this year.
"In many respects the pressure is off us because we've achieved a triple double world championship," Horner said.
"But we put the pressure on ourselves because we want to continue that run of success.
"Of course, going into the season as reigning champions, you're there to be beaten, you're there to be shot at.
"But it's something we've got used to over the last couple of years. Pressure is part of this business, it's part of this sport," Horner said.
