How does KERS work?
- From the section Formula 1
BBC Sport's Gary Anderson visits the Mercedes factory in Brackley to see how KERS, short for Kinetic Energy Recovery Systems, 'harvest' energy to allow Formula 1 drivers their 'boost button' which provides them with an extra 80bhp for 6.67s per lap.
Drivers operate their Kers button to aid overtaking and defence during races.
