Kilowatt hour (kWh) is a unit of energy, often used to measure the storage capacity of a battery.

A kilowatt hour is the amount of energy used when a power of 1000 watts is used for one hour.

A Kinetic Energy Recovery System or KERS collects or 'harvests' waste energy during braking, and allows that energy to be re-used later to help accelerate the car.

KERS can be an electrical system using motor/generators and an electrical battery, or the energy can be stored in a flywheel and used by either an electrical or mechanical system.

Formula 1 cars use KERS to promote overtaking, and Porsche has run a 911 GT3 racing car with a flywheel KERS.

King pin inclination is the angle to the vertical of the steering axis, when viewed from the front of the car.

The king lead is the high-tension ignition lead which takes electrical energy from the ignition coil to the distributor. It has been rendered largely obsolete by modern distributorless ignition systems.
