KERS - Kinetic Energy Recovery System

Nick Heidfeld has said that BMW Sauber has yet to make a decision on whether the or not they will be using a kinetic energy recovery system for the opening race in Melbourne, Australia.

Williams and Toyota have stated that they will not have cars with KERS on the starting grid. Red Bull has announced that they might postpone the introduction of their KERS system.

BMW Sauber is believed to have one of the most advanced kinectic energy recovery systems and has been one of the biggest supporters of the technology in Formula 1. The precise benefits gained by using the KERS is still not known. While the system delivers an instant horsepower boost at the driver’s command, the system adds an additional 40 kg of weight to the car, changes the weight distribution, raises the center of gravity, needs more cooling, and affects stability in braking. And then there is also the question of reliability.

“Reliability seems quite good and we are testing it quite often, not all the time, but on and off to understand the benefits that we will hopefully have,” Heidfeld stated on the Formula 1 website.

Flywheel and KERS – Racing Auto Parts

In a traditional vehicle, the flywheel is the large wheel connected to the crankshaft that provides the momentum to keep the crankshaft turning while power is not being applied. The momentum is created by the energy generated during the power stroke. This energy is also used to drive the crankshaft, connecting rods and pistons during the three idle strokes of the 4-stroke cycle. This makes for a smooth engine speed. The flywheel forms one surface of the clutch and is the base for the ring gear.

Flywheel and KERS


The upcoming season of Formula 1 will allow teams to incorporate the new Kinetic Energy Recovery System (KERS) system into their cars. This addition will essentially turn the cars into hybrids. KERS is not a battery electric hybrid technology that most people are familiar with. The recovered energy is stored in a rotating flywheel instead of being converted into electricity and then applied through an electric motor. The flywheel is approximately 5 kilograms and contained inside the car’s transmission. This stored energy in the flywheel can be used by pressing a boost button during certain times of the race.
