Thanks for the correction. I did a little research, too.

The answer is E vehicle's much higher efficiency.

An internal combustion engine has a thermal efficiency about 26% and mechanical efficiency 94% mechanically efficient. This means that for a stock engine, only 20% of the power in fuel combustion is effective.

Thanks to higher efficiency, to drive a conventional size electrical car at freeway speeds requires about 10 to 14 horsepower – 7.5 – 10.5 Kw. That gives us a much better numbers.

The annual survey by an independent consulting company, NUS Consulting Group, Park Ridge, N.J. found the average price of electricity in the United States was 9.28 cents per kilowatt-hour (kWh) as of April 1, 2007 ( ecmag.com )

Assuming 10 cents/KwH, we are talking about $0.75 – $1.05 of EV vs $7 of gasoline car for one hour driving.

Gas is only economically competitive at about $0.50/gallon.
