if the answer is a regular car, how can hybrids possibly be more efficient than a regular car, since some of the power from the gas engine goes to the generator for the electric motor.
It is about inertia and storage. Hybrid is a new technology and it is more efficient, but they lack performance something the American car market still craves. Did you know that all Diesel locomotives in the US are hybrid and have been for decades? The diesel engine charges batteries and electric motors provide the actual drive.
