Sauber technical director James Key has revealed that the Swiss-based outfit found some 'new directions' during the recent four-day test at the Circuit de Catalunya.

Speaking following the final day of testing on Monday, he confirmed that the squad will try out the first part of its update for the start of the F1 2011 season at the second test at Barcelona in two weeks time.

"It was the final day of quite a long test in Barcelona [on Monday]. It's always good to use this track as a reference. You get a far better idea about what your car is doing and where its strong and weak points are," Key said.

"We spent most of the time on day four working on the set-up of the car, and we tried some new test items. We have to look at the data, but certainly we found some new directions.

"We also found some useful directions with the different compounds of tyres between the start in the morning, which was cold, and the afternoon when it was quite warm. The temperatures, the set up and the tyre compound are all very closely linked. There's a lot of factors to consider, and we were able to learn more about all of them.

"Now we head off to the next test where we will introduce onto the car the first part of the update for the start of the season."

Sergio Perez, who was in action in the Sauber C30 for the final day, completing 74 laps in total, added: "It was another positive day. I learnt a lot, in particular about the tyres.

"They kept changing, but now we have the final spec for the beginning of the season, so it was good I was able to run them today to learn how to maximise their potential. We did a lot of work over the two days, so I'm quite happy," he summed-up.
