Basically, if we consider the automotive world, companies try hard to come up with something that could boost fuel economy. According to that, the most common system which is used today is a hybrid arrangement. It uses batteries and electronic motors to help push the vehicle. Besides, green system is another arrangement, a KERS flywheel just similar to the one used on the Porsche 918 RSR racecar.

Following this, Volvo is now on the verge to test the KERS flywheel tech. It has also received a grant from the Swedish Government that is the Swedish Energy Agency who offered 6.57m Swedish Kronor (£640,000) just to test the capability of flywheel technology on public roads.

Volvo is set to use this money into development of the next-generation technology for kinetic recovery of braking energy, as said by the company. The system works in a particular way. It shuts off the engine of the car, making it run on the front wheels. Just when the brake is applied the car employs 60,000 rpm flywheel through a specially designed transmission which accelerates the vehicle and also offers power to the car at cruising speeds right from its rear wheels.

This technology has got potential to reduce the fuel consumption of the car by 20% as said by the Vice President VCC Powertrain Engineering Derek Crabb. Also, he added that this technology offers the driver with a boost of additional horsepower through a 4-cylinder engine which accelerates like a 6-cylinder unit. Due to the addition of the carbon fiber flywheel, the vehicle will get up to 80bhp with the improvements in torque.

Crabb has said that if in case the tests and technical development go as per the plans, then the company expects that the cars with flywheel tech will be available in the showrooms in just a few years.
