The hybrid vehicles on the road in the US today (Honda Insight & Civic Hybrid, Toyota Prius) have two engines, a regular ol’ combustion engine as well as an electric motor. My main question is: Can you drive these cars without gasoline in the tank, i.e. solely on the electric batteries?
One of the defining features of these cars is that they start moving under electric power only (unless you goose it), so I know it’s technically possible. Any dopers got one to test out? Also, how fast/far would you be able to go under electric power only?
