Although BMW's Formula 1 team has had its fair share of troubles
getting the Kinetic Energy Recovery System (KERS)
to work properly, those minor setbacks may not be enough to stop the Bavarian automaker from using a similar system for its line of high performance M Division vehicles. The sophisticated hybrid system uses a high-speed flywheel to store energy which would otherwise be lost while braking which is then fed back into the driveline when the vehicle next needs to speed up. Besides being more efficient than battery storage, the KERS system is significantly lighter, coming in at just fifty-five pounds in racing configuration. On a production car, the KERS system could be combined with a much smaller battery and electric motor for true full-hybrid operation.
If these rumors hold true, the Federation Internationale de l'Automobile's (FIA) goal of letting racing perform the research and development for new car technology would be achieved. We'll just need to wait and see
how effective the innovative hybrid system proves in Formula 1 before making any judgements.
