BMW Sauber team boss Mario Theissen has poured cold water on suggestions that his squad would be better served by canning its 2009 programme and focusing on producing a winning car for 2010.
Writing in his regular post-race column on the team's website, Theissen was adamant that there would be no quitting on the current programme, with further developments in the pipeline that he hoped would turn the F1.09 into frontrunner.
The 2009 season, BMW Sauber's fourth as a constructor, was supposed to be the one in which the team challenged for the world title, but a change in the regulations, plus its off-season focus on the introduction of KERS technology, appears to have derailed the Hinwil concern, with neither Nick Heidfeld or Robert Kubica in a position to take on Jenson Button and Brawn GP.
Indeed, without the sort of double diffuser that Brawn - as well as Williams and Toyota - used to good effect in the opening three races, and with its KERS failing to live up to the amount of work invested in it over the winter, BMW Sauber has just eight points, with Kubica - who finished fourth overall in 2008 - not opening his account until Istanbul at the weekend.
The Turkish round was notable for the belated introduction of BMW Sauber's take on the diffuser situation, with a double-deck version being introduced as part of a wider aerodynamic update, and Theissen is adamant that the development is just the first of a series designed to restore both morale and reputation ahead of 2010.
"I'm often asked these days, if it wouldn't be better to simply stop working on the enhancement of the F1.09 and fully focus on our 2010 challenger instead," Theissen wrote, "But this doesn't represent an option for us.
"We won't give up on the current season - far from it! We have increased our development pace, and will bring significant improvements for the car to every second or third race from now on - improvements that will also comprise enhanced of the twin diffuser.
"At the end of the season, we want to be able to say 'we encountered a disappointing start to the season, but we succeeded in turning things around and making it back to the front end of the field."
Revealing that the introduction of the new diffuser required a major reworking of the car, notably at the front as well as the rear, Theissen admitted that the effort had been worth it.
