If only this is rumor true... it would mean that Redbull has a KERS system that can control wheel slip based on downforce generated by the car, because traction control of any form based on engine rpm is banned. And it would somewhat explain why Redbull's KERS failed so often on Webber's car. You would need to be a robot to adapt to driving such a system.
