Zoom Klien getting on better with KERS than Kubica

For the third and final day of testing the BMW Sauber team used two interim cars, which were based on the 2008 chassis with some of the bodywork from the 2009 regulations.

In Jerez the team came as close as could be to the test kilometres and sets of tyres allocated for the 2008 testing season.

In the morning Christian Klien drove the KERS’ equipped F1.08B. Working on different energy strategies, the team continued the development work as scheduled.

"“We made good progress today”," Klien said. "“We still have a lot of work to do on the KERS system. But the promising test results show we are moving in the right direction.”"

Robert Kubica in the sister car, but without KERS, tried numerous set-ups aiming to improve on the results from using the new slick tyres. For the afternoon session, according to the plan, he switched to the KERS’ equipped car, but due to a mechanical failure he had to abandon the scheduled programme.

Kubica then got back into the conventional F1.08B and continued testing for the rest of the day.

Today was the final test day of 2008 for the team.
