The flywheel system intrigues me. Two(?) F1 teams ran this type of KERS system a couple of years ago. I'm wondering how long it will take to get to a production model.

what flywheel system?

^^^The two main systems used in the KERS (kinetic energy recovery system) used were the flywheel and the brakes. One system would recharge a battery under braking while the other recharged the battery while the flywheel was spinning. I suppose you could use the spinning wheels to recharge the battery too.............maybe that's how they did it, anyhow two main systems.

The neat thing about the flywheel is even in parking lot traffic you should be recharging the battery since the flywheel is turning. Neat system to use on an internal combustion engine setup. If the car goes full electric at slow speeds then neither system is probably going to be doing anything but going along for the ride.

The technology is interesting and would be neat to see how it transfers to mass production cars.

Recharging while braking is using the wheels, not really using the brakes. It does perform braking since torque is developed as a result of the current created in the generator function of the motor....confusing enough.


The Honda hybrid system uses the engine flywheel (or something right there anyway) as the rotor for the electric motor/generator, and it does charge the battery at idle (if the engine is running) since there is no alternator.

interesting
and looks bad ass!
