Most of the teams and FIA president Jean Todt have acknowledged the need to incorporate more relevant technology in the future; engine downsizing and KERS are both being discussed. While no one is using KERS in F1 this year, the McLaren system, which was developed with Zytek Engineering, was used by Corsa Motorsports in its American Le Mans Series car in 2009. Williams had the most unique system with its electromechanical flywheel setup. That system is actually being used this year by Porsche in the experimental 911 GT3R Hybrid which will run in the 24 Hours of Nürburgring this weekend. A decision will have to be made soon so that teams have time to incorporate the systems into their 2011 car designs.
