Audi R18 e-tron quattro: diesel hybrid Le Mans racer with electric flywheel energy storage

Green Car Congress

On the Audi R18 e-tron quattro, kinetic energy is recovered on the front axle during the braking phase. Power from the Motor Generator Unit accelerates the carbon-fiber flywheel, which runs in a high-vacuum. After the corner is taken and the driver accelerates again, the system delivers the energy to the front axle.

MHI to supply 2 electric buses featuring MLIX Li-ion batteries for Kitakyushu City

Green Car Congress

In combination with a lighter body enabled by the partial adoption of carbon fiber construction, the new buses will be able to operate continuously over increased distances—up to 80 kilometers (50 miles) on a full charge, at a top speed of 85 km/h (53 mph). Load capacity is 72 passengers.

Volvo Car and Flybrid vehicle testing showing flywheel KERS can deliver fuel savings up to 25%, with significant performance boost

Green Car Congress

Under braking, kinetic energy which would otherwise be lost as heat is transferred from the wheels to the KERS, and is used to spin a 6 kg carbon fiber flywheel at up to 60,000 revs per minute. Since the flywheel is activated by braking, and the duration of the energy storage—i.e., —Derek Crabb.

Shanghai General Motors introduces Sail SPRINGO EV at Auto Guangzhou 2012; green technology strategy to 2020

Green Car Congress

The top speed is 130 km/h (81 mph). Electric range is 130 km (81 miles) under a variety of road conditions and 200 km (124 iles) at a constant speed of 60 km/h (37 mph). More balanced power output with regenerative braking helps keep energy consumption at the lowest level. The Sail SPRINGO EV costs RMB 4.6 (US$0.74)
