Not enough range yet for me and no as efficient as a hybrid.
Let's go through the numbers.
By comparison one gallon of gasoline is 33.7 kw hours.
A gasoline engine is 32.5% efficient
So out of every gallon of gasoline you use you only get 10.95 kw hours. So for 50 mpg that means you use 0.219 kw hours per mile.
100 miles * .219= 21.9 kW hours.
Tesla figures 34 kW hours per 100 miles. So a Tesla is 64% as efficient as a gasoline engine getting 50 mpg. So my Prius is 33% more efficient than a Tesla. The electric motors must be generating a lot of heat!

@Tastyfrzz They do. Almost all electrical equipment, and most moving machinery of any type anyway, loses some energy by converting it into heat. Hence the cooling-fan built into most motors or clamped to the CPU in a computer.
If your petrol Prius is lighter than its nearest all-electric equivalent, it obviously also gains by less of its own mass to accelerate and keep moving - but that might be partly compensated for by the BEV lacking an alternator, cooling-fan and pump; and in many models by regenerative braking.
