The BMW team may take the decision not to run the Kinetic Energy Recovery System (KERS) at Sepang this weekend. Due to the weight of the device, the team elected to use the system with Nick Heidfeld only in Australia, but is unsure as to whether or not KERS would in fact hinder the car's performance in the baking Malaysian temperatures.

BMW's decision may have been assisted by the fact that Räikkönen's Ferrari returned to the pit lane with smoke rising from its cockpit at the end of first practice, with the first KERS-related failure resulting in toxic fumes drifting across the pit lane as the device overheated.
"We stuck to our planned programme on Friday and concentrated on race preparation," explained Willy Rampf, BMW's head of engineering. "One focus point was the comparison of tyres over long runs. Apart from that, we tested two different options with Nick today - in the first session he drove with KERS and in the second without it, for two reasons; on the one hand we wanted to get a direct comparison, and on the other hand we wanted to practice changing in between the two sessions, and did it without any technical problems."
