It would stop the car faster. By the same logic your using it would be equally hard to push a car backwards with the wheels spinning as it would with its wheels locked. Spinning wheels generate friction which moves a car forward or backwards. If a car spins its wheels backwards during forward...

How strong would the braking effect be? Comparable to disc brakes, or alot less? Could you stop a car alot faster by switching the polarity and/or applying disc brakes? Electric motors have alot of torque, maybe there could be a system if you slammed on the brakes it locks the tires with...

Q: Can the polarity of an electric motor be switched during operation to create a braking effect? thanks

id like to add... It will have 'more interior room and much more cargo space than the 5 series BMW' (The current BMW has 14cubic feet of trunk space.) , will be able to accommodate 3 child seats

Ev-battery is selling A123 systems batteries! If I had 168k lying around to pay for 1000lbs of these batteries and a bit more to pay for 4 of these, and an AC inverter, I would build the fastest 1/4 mile / street car ever. 1000lbs of these batteries make 1.62 million watts of power which is...
