Volvo tests out KERS for passenger cars

We've all heard the technology spoken of in Formula 1 commentaries, but now KERS could be featured in Volvo's future passenger cars.

The company is testing out the power boosting system in an S60, with the 'Flybrid KERS' (Kinetic Energy Recovery System) added to the rear axle. 

It allows the car to harness the energy created by braking, with the heat transferred to a six kilogram fibre flywheel which can spin at up to 60,000 revs per minute. 

When the car moves again, the energy stored is sent back to the rear wheels for added power or a reduction of the engine load.

This means the car can benefit from an additional 80hp performance, while fuel consumption is minimised by 25 per cent. 

If the system is successful, it will be most beneficial when in city traffic as the energy stored from the flywheel is enough to power the car for short periods. 

Derek Crabb, vice president of powertrain engineering at Volvo Car Group, said: "Our calculations indicate that it will be possible to turn off the combustion engine about half the time when driving, according to the official New European Driving Cycle."
