Will the Chevy Volt really get 230 mpg?

Measuring MPG doesn't make a lot of sense for a car that gets plugged in. Miles per dollar would be a lot more interesting, but with this style of vehicle it depends highly on your daily usage. This is a great marketing hack.

Yes, if you don't mind pushing it.

Nearly fell off my chair laughing. Thank you :-)

For me it would get a lot more than that. I only drive more than 40 miles in a day about a half dozen times a year.

You'll have to pay for the electricity though. I wonder how efficient the onboard generator is. There are losses for sending electricity through power lines, on the other hand gas is expensive due to taxes.

I would like to see numbers for KW/gallon for the onboard generator. Then we could compare generating your own electricity to power it, vs storing it from power lines (and don't forget losses in the battery, and self discharge).

Gas is also expensive because your engine wastes 4/5 of each gallon you buy.

Electric is 4x as efficient as ICE. So could you get from 50mpg to 200mpg? yeah. Will Chevy? no.

In the context of a plug-in hybrid, what does the "gallon" in "miles per gallon" mean?
