Does your hybrid respond as well as a non-hybrid? Have you seen any savings at the pump (mpg)?(how much? slight/drastic - just curious)
Most hybrids, when compared to their gas-only counterparts, have more torque because the electric motor in addition to the gasoline engine (internal combustible engine [ICE]) work at the same time during sudden acceleration, ie, 0 to 60 mph time for a hybrid is usually faster than a gas only vehicle. During slow drives, like during street traffic, traffic jams, driving around a parking lot, stopping at a street light, the ICE completely shuts off and it just runs on the electric motor. With an immediate push of the pedal, the ICE turns on without lag to help the electric motor. New York taxis are starting to use hybrids.
Electricity is generated from braking. The kinetic energy of motion that would usually be wasted/dissipated as heat on the brake pads during regular braking, is used to produce electricity through a generator attached to the brakes, and the electricity is stored in battery cells. The stored electricity in the batteries then power the electric motors. No such thing as plugging the car into an electric outlet.
Definitely have saved at the pump. For example, if I drive a round trip between Miami and Orlando (7 hours), I dont even have to get out to get gas and I have fuel to spare.
Yes the EPA's estimates for all cars have always been way off mark when compared to real world driving, this is the case for gas-only vehicles since history, and now scrutinized because of the emergence of hybrid vehicles. The EPA estimates have been proposed for a complete revision of their methods. So DanC, your monster mobile is probably doing 12 mpg, unless you have actually calculated the number of miles for every gallon you have filled in your barge, using gas receipts (highly unlikely and out of character for someone who bought a napoleon mobile).
Here are the real world mpg for the current hybrids
