Formula One is going hybrid starting next year, according to statements released by the sport's governing body the FIA. The Kinetic Energy Recovery System (KERS) will be phased in over a period of several years, starting with the 2009 season and culminating with the full-fledged implementation by 2013. The system works essentially by storing energy expelled under braking, which can then be used via a "push-to-pass"-style button mounted on the steering wheel that drivers can employ for an extra power boost.
