Volvo to test flywheel technology in autumn

Volvo cars featuring new flywheel technology, which is designed to make a four-cylinder engine feel like a six-cylinder while retaining eco-efficiency, will be road tested later this year.

After receiving a grant of 6.57 million Swedish krona (£650,000) from the Swedish Energy Agency, Volvo will begin testing the kinetic energy recovery system in autumn.

Flywheel technology is fitted to the rear axle of the car and recovers braking energy, transmitting it to the rear wheels to save fuel and increase power.

Derek Crabb, vice-president of VCC Powertrain Engineering, said: "This technology has the potential for reducing fuel consumption by up to 20 per cent.

"What is more, it gives the driver an extra horsepower boost, giving a four-cylinder engine acceleration like a six-cylinder unit."

Volvo also recently tested its C30 Electric car in tough winter conditions to ensure the battery-powered vehicle is not affected by the cold, finding it could withstand temperatures as low as -20 degrees Celsius.ADNFCR-2576-ID-800564452-ADNFCR
