FOTA votes against KERS for 2010
It is not known if the decision, voted for by the majority of the eight remaining member teams on Sunday, will be part of FOTA's demands as per their conditional entry to next year's world championship.
Earlier, it would have been possible for FOTA to simply vote against KERS and not seek an accompanying rule for 2010, as using the energy recovery systems is voluntary.
However, because Williams and Force India have been expelled from the body, it is now more difficult for FOTA to implement an unanimous agreement to keep the legal technology off all F1 cars in 2010.
Only McLaren and Ferrari used KERS in Istanbul this weekend, but even so BMW's Mario Theissen did not vote to ban the systems.
"We have voted in favor of KERS but, as in all the FOTA decisions before, we will go with the majority," the German said.
