Volvo Develops Hybrid KERS Flywheel
Two years ago we reported that Volvo were testing a clever hybrid Flywheel KERS system for road cars and hoped it would prove to be a good way to make road cars more economical. And it seems it does.
The Hybrid Flywheel KERS system Volvo has developed weighs only 6kg, has a diameter of just 20cm, is made of carbon fibre, sits in a vacuum and is located on the back axle and works by recovering energy under braking which is then stored for use when the car moves off.
After braking to a halt, the KERS Flywheel kicks in as the driver sets off, giving instant torque and making for a swift take-off before the engine, which has been stopped as the Flywheel kicks in, restarts to continue the journey.
