It's green for go [Control]

In late 2007, governing body of the Formula one mtor, F1A announced it was freezing the specification of F1 engines to encourage car makers to develop environmentally friendly technologies such as KERS - a form of regenerative braking making them the only means for the present by which teams can gain a power advantage. KERS technology takes a moving vehicle's kinetic energy, which isotherwise wasted during braking, stores it, and then releases it back into the drivetrain as the vehicle accelerates. One reason behind the FIA's move is to promote the use of eco-friendly technology in road cars by helping manufacturers sell it to the public through its use in F1. Another reason is the thinking behind the freeze on engine design. The third reason is to save money by ensuring the sport's engineers do not pursue technologies that are not relevant to road cars.
