BMW Sauber will not write off the 2009 season

Unlike Ferrari, BMW is not close to assessing whether or not to write off the 2009 season, team boss Mario Theissen insists.

It was reported on Monday that, after another point-less weekend in Shanghai, Ferrari will sit down after the forthcoming Spanish Grand Prix to consider turning all efforts to regrouping in 2010.

BMW Sauber at least has a few points on the board, but is far from its pre-season ambition of being in a position to fight for the championship.

"We are not content with our start to the season, but we will not give up our goals after the third of 17 races," Theissen is quoted as saying by Germany's SID news agency.

"We must understand the car's shortcomings," the German continued, "and make big steps forward from now. The arrears is able to be recovered."

Theissen, however, acknowledged that because the 'double diffuser' solution is more complicated than it appears, a fully-developed version may not be part of the major Barcelona upgrade.
