Ferrari technical director Aldo Costa says he is 'satisfied' by what the Scuderia has seen from Formula One's new KERS system so far, although he has predicted that more trouble with the system could lie ahead.

The team saw its running on the second day of this week's test session in Bahrain hit by a KERS failure that left Kimi Raikkonen parked in the garage for the best part of three hours, although the failure did give the team chance to experiment with an emergency in case of a KERS failure. Raikkonen also went on to post the quickest time of the day on his return to the track.

Despite a gearbox issue in the morning, team-mate Felipe Massa was able to continue putting miles on the new F60 and the KERS system during Wednesday's penultimate day of running.

However, Costa warned that the team could still run into some problems with the new electrical system in future as it continues preparing for the season opener in Australia.

"We're coming close to the end of this long test session here in Bahrain and the days are more and more intense," he said. "We have to exploit what the rules permit in terms of tests, as far as reliability, development and research in terms of performance are concerned.

"There might be some problems ahead, like the ones we've had over the two days with the completely new components of the KERS or with experiments, like the ones we had on the gearbox this morning. As far as the KERS is concerned I have to say that we're quite satisfied with what we've seen so far, although there's still a lot of work to do.

"We used a standard configuration for the aerodynamics here in Bahrain, with just some minor updates: the complete one we'll see at the next tests in Jerez and Barcelona, where we will conclude our preparation for the Australian GP."
