When I take people for a demonstration drive in my Chevy Volt, I have to remind them that I am not hitting the “gas pedal”, I am using the accelerator pedal. The pedal has no direct connection to the gas engine generator that GM refers to as a “range extender. The pedal is hooked into the control computer of the vehicle and its only function is to modulate the amount of energy going to the electric motor. It is interesting to note that when you put the accelerator to the floor, my energy gauge shows around 80 kW of power going to the motor. Yes that’s Eighty. Thousand. Watts! That is a truly enormous amount of energy! And no gasoline involved unless I am running in range extender mode, in which case the four-cylinder gasoline power generator can contribute up to 50 kW to the battery to help maintain a safe battery level. There are times when that engine generator will ramp up to over 4000 RPM, and you really hear it, but most of the time it is barely audible.
