Have you solved the mystery of the Chevy Volt 230 mpg and the Nissan Leaf 367 mpg? I have?

I'm not sure, davepamn. It is interesting that even GM is not publishing the formula they used to calculate their mpg number. They say the EPA hasn't approved it yet.

I have seen a few attempts to come up with it (see above in the question) but all have the same flaw. Electricity has to be part of the equation. There are no "free" miles the car drives when using the battery only.

We pay for the electricity like gasoline (the battery is not much different than a gasoline tank in the car). If the electricity would be free - a pure electric car would come out with an infinite number of miles per gallon. And the Nissan Leaf is a pure electric car.It does not have a gasoline engine to drive it when the battery is empty.

The Nissan guys probably are very correct with their number of 367 mpg. Riskier of getting stranded? Not really.

A single charge will last for 100 miles. Good for a commute 80% of us go through every day. Just don't forget to plug it in in the evening!

Nissan also claims to do all that for a price 40% less than the Volt! When I heard that I remembered GM's debacle with the EV1. Their first full electric car that could go about 60 miles on a charge, a decade ago... If they would have kept that line going, they would own the EV market today.

Back to the question. The formula is still AWOL. I'm still digging.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
