Hybrid cars are vehicles that include a motor/generator to assist both the engine and the brake. The motor/generator is attached to a relatively large rechargeable battery and the interactions between the engine and the other equipment are computer controlled. The motor/ generator assists the engine during acceleration by allowing the battery to power the motor/generator as a motor. When decelerating, the motor/generator acts as a generator and uses the car’s motion as energy to recharge the battery. This slows the car while assisting the brakes. Thus, part of the car’s motion is turned into electricity that is stored for reuse later when additional pickup is needed. No other gasoline car has this feature called “regenerative braking.” Conventional braking involves friction which literally
