Maybe the electric motors are less waste heat. I suppose so, no radiator for cooling.
Turn on the AC or Heater and see how far you get.
Go up hill and see how it does. Face a stiff headwind and see what it does.
I think hybrid cars are a good thing. But I don't think all-electric cars are ready for primetime. When driving my daughter's hybrid, I press the Start button and silently glide away, very cool. However, flick on the AC or heater and the gas engine comes online. Accessories really do eat power from the batteries. If you do nighttime driving, even more of a drain from headlights and taillights. Add extra passengers and you're pulling around more mass which drains power. At least with a hybrid, you're replenishing the batteries while on the move.
