The disavowal of Srec?

Following reliability problems encountered in Malaysia, Ferrari announced even before the start of the weekend its intention not to use the Srec. Then it was the turn of Renault to give up last night after having made Nelson Piquet ride with the system on Friday. On the BMW side, Robert Kubica having not been able to manage the excessive degradation of his tires due to the excess weight generated by the SREC, the decision was made to dismantle it.

Result, when it came time to approach the qualifying session, only the two McLaren de Lewis Hamilton and Heikki Kovalainen, plus Nick Heidfeld's BMW-Sauber are equipped with SREC.
