Kinetic Energy Recovery Systems (KERS) were used for the motor sport Formula One's 2009 season, and under development for road vehicles. Its is being mainly used by Ferrari, renault, BMW and Mc laren. Tt raises the car's center of gravity, and reduces the amount of ballast that is available to balance the car so that it is more predictable when turning. physicist Richard Feynman postulated the theory of transferring the vehicleâ„¢s kinetic energy using the method of Flywheel energy storage. Zytek, Flybrid, Torotrak and Xtrac are the conventional systems available.

Use in motor sport
History
Flybrid was the first system to be revealed. It weighed 24 kg and has an energy capacity of 400 kJ . It could provide a power boost of power boost of 60 kW .

FIA
FIA allowed the use of 81 hp KERS with some regulations. energy can either be stored as mechanical energy in a flywheel or in a battery or supercapacitor as electric energy.

Autopart makers
Bosch Motorsport Service is an active developer of KERS for motorsports. lithium-ion battery , flywheel, capacitor etc are used to store energy.

Carmakers
Many manufacturers like Honda has been testing KERS systems. Peugeot 908 HY is an Hybrid vehicle with KERS.

Motorcycles
KTM racing used a motorcycle with Kinetic Energy Recovery System (KERS) fitted to Tommy Koyama's motorcycle during the 2008. It was illegal and they were warned.
