Sauber technical director James Key said he was pleased with the team's first day of running with the new C30 as F1 pre-season testing kicked off in Valencia.
Kamui Kobayashi was on duty for the first day of the test and managed 68 laps as he posted a best time just under two seconds away from the benchmark set by defending champion Sebastian Vettel.
Having taken on the job of completing the system checks required with the new car, Kobayashi will now hand it over to team-mate Sergio Perez for the remaining two days of running.
“It was a bit of a trouble shooting day, as we had to check all the various new systems and sort things out,” the Japanese driver said. “But that is no problem, as it is something you just have to go through. However, due to the work with the new systems we had no time for proper performance runs.
“The grip of the new tyres dropped off quite quickly. This is something you can improve with set up work, but for the reasons mentioned we did not really have time for that. Anyway we will continue to learn.”
Technical director James Key, who helped to oversee Sauber's fightback from a difficult start to 2010, was pleased with the first day of running for the C30 although he admitted that the degradation of the new Pirelli tyre had been slightly higher than expected.
“It was a busy day, with all the little problems you have to look into at this time of the year when testing begins with a brand new car,” he said. “The important and good thing is we had absolutely no major issues and the car was running well.
“We used the morning for several system checks and some initial set up work. We only used the KERS and the rear wing activation in the afternoon. Tyre degradation was quite high and we will have to keep an eye on that for the remainder of the test. Of course there is plenty of work to do, but we are fine with what we have learned and achieved so far today.”
