Volvo video highlights KERS

A short video on the directorstalk.com website posted on 20 April 2013 in conjunction with Volvo Cars highlights the benefits of the Torotrak/Flybrid Kinetic Energy Recover System (KERS).

The flywheel KERS is fitted to the rear axle. During retardation, the braking energy makes the flywheel spin up to 60,000 rev/min. When the car starts moving off again, the flywheel’s rotation is transferred to the rear wheels through a specially designed transmission.

The fuel consumption can be reduced by some 25 per cent. Also, the power of the engine is boosted and the car’s acceleration improved.
