I just got a 500e about a week ago. I like it so far. However I have noticed some odd behavior by the climate control system. Ic seems like it impossible to turn off the AC. In most cars you can turn off the AC and just run the vent fan in the cabin to add some air flow. This typicaly does not affect the mileage of a gas powered car because the clutch on the AC pump stays disengaged. In an AC system the vent fan draws very little current compared to the compressor. However, whenever the blower motor is on in the 500e it cuts down the range estimate by about 10%. I read on another forum that if you continue driving the car the range estimate will creep back up because the system assumes worst case scenario when the climate climate control is initially turned on even if the AC is off. This seemed logical enough to me until I started doing some testing.
I parked the car and started turning on and off the ac button. It made no difference. I could hear the AC pump cycling on and off periodically with the ac button lit or unlit. The only way to turn off the pump is to turn off the system completely. I'm not confusing the vent fan with the AC compressor. I know how air conditioning works. This seems really silly on an electric car with a very limited range where every KW is precious. I know I could just roll down the windows but I don't want the noise.
