Volvo unveils Flywheel KERS system image

Swedish automaker Volvo has announced that is testing a system similar to that one found on Formul1 Cars ( Kers ). Practically Volvo plans to bring a similar Kinetic Energy Recovery System (KERS) to the world of production cars.

While for some peoples this doesn’t sound terribly exciting, the automaker says the FKERS is “a light, cheap and very eco-efficient solution that makes a four-cylinder engine feel like a six at the same time as fuel consumption drops with up to 20 percent.”

Practically how KERS works? The KERS system is fitted to the rear axle of the car (displayed in video). When braking, the energy causes the flywheel to spin at up to 60,000 revs per minute. When the car starts moving again, the flywheel’s rotation is transferred to the rear wheels via a specially designed transmission. This energy can be used to accelerate the vehicle or power it once it reaches a cruising speed.

As the flywheel is activated by braking and the duration of energy storage is limited, the technology is most effective during repeated stops and starts – meaning the fuel savings will be greatest in busy urban traffic.

According to Volvo, paired with a start /stop system and an internal combustion engine, the new KERS can provide an additional 80 horsepower to an engine and at the same time reduce its fuel consumption by 20 percent.
