From wikipedia:
Along with changes to bodywork, vehicle weight and tyre size, the document includes details of a "Kinetic Energy Recovery System", or KERS. This is a regenerative brake device that is designed to recover some of the vehicle's kinetic energy that is normally dissipated as heat during braking. The recovered energy could be stored electrically, in a battery or supercapacitor, or mechanically, in a flywheel, for use as a source of additional accelerative power at the driver's discretion.

It sounds like very interesting~

sure it is, i think eletric and hybrid cars have this feature for battery recharging or something like that..

but i personally don't like "temporary boosters" in a race, so it's a -1 from me

Sorry but no. I am happy if people pass me because they diver better or because I mess up. Not because they have hit a button that makes them faster for X seconds.
