The above statement is only a little in error.. regen does NOT add any range. It merely uses a generator on the wheel to capture some of the energy used for accelerating instead of wasting it in heat. You will still get the same "RANGE" in a vehicle that has no regen if you coast to a stop. That is the maximum range of the vehicle. Regen doesn't add to it, it just makes your driving a little less wasteful. My E-10 has a switch to turn on or off the regen. I drive most of the time with it off and coast until I have a need to stop in traffic. Also when in regen the accelerator pedal controls the amount of regen.. nice setup. IMHO that's the only way regen should be implemented. I have a route that I have traveled hundreds of times. Using this out of the way route, with little or no traffic, I use 1.0 to 1.1 Ahr per mile without regen, and at times that I have traffic, I use 1.15 to 1.2 Ahr per mile using regen. That's the courteous driving penalty. REM: The energy used to accelerate is the only energy you can recover a portion of, the energy used to maintain speed and travel from point A to point B is lost forever. Think about it.. how efficient is the generator on the wheel for charging a battery? I'll use my Zivan thank you.
