No change to BMW floor in Malaysia – Heidfeld
"For us, there is no new system," 29-year-old Heidfeld told reporters on Thursday at Sepang.
It was thought that BMW-Sauber and Ferrari were most affected by the FIA's clarification, after McLaren unofficially protested the design to the FIA following the season opening Melbourne race.
World champion Fernando Alonso suggested that even if McLaren's rivals have modified their cars, it is unlikely to drastically alter the hierarchy in Malaysia.
"Maybe they had some advantage there," said the McLaren driver on Thursday, referring to Australia, "but I don't think it will now be a change like day and night."
Alonso insisted that he is not surprised that Ferrari is currently dominating the pecking order in formula one.
He said: "For us it has been a big change after a bad season in 2006. So I think it is quite normal we are not 100 percent like Ferrari."
