Volvo: Fuel savings of 25 percent * Sweden
* Sweden - Volvo confirms fuel savings of 25 percent with flywheel KERS
(Image: Volvo's Flywheel KERS)Goteborg,Sweden -Gizmag, by C.C. Weiss -April 26, 2013: -- After extensive testing of its kinetic flywheel technology, Volvo has announced that the system can boost fuel economy by 25 percent. The company is now looking at integrating the Flywheel KERS system into its production line... Volvo's Flywheel KERS is fitted to the rear axle. During deceleration, the braking action causes the flywheel to spin at up to 60,000 rpm. Meanwhile, the front-mounted engine shuts off. The energy stored in the spinning flywheel can then be applied via a special transmission toward acceleration or used to power the car once it reaches cruising speed... Volvo's experimental flywheel is a carbon fiber model that spins in a vacuum to minimize frictional losses. It weighs 13.2 pounds (6 kg) and measures about 8 inches (20 cm) in diameter... During road testing with a Volvo S60 flywheel test car, Volvo found that when partnered with a four-cylinder engine, the flywheel technology offers up to a 25 percent reduction in fuel consumption versus a comparably performing turbo six-cylinder. It says that the system can also augment the engine with an 80 hp boost, giving it acceleration comparable to a six-cylinder – 0-62 mph (100 km/h) in as quick as 5.5 seconds...
