The batteries carry 92 kilowatt-hours, or enough to power an average American home for three days -- or drive the car 372 miles, enough to get from New York to Pittsburgh.

92 kilowatt-hours is the energy equivalent of 2.6 gallons of gasoline (at 34 megajoules per liter). Even considering that gasoline engines are relatively inefficient compared to electric motors (just don't ask any questions about whether the inefficiencies are moved back to the electric generation plant), that is pretty darn impressive.

Which would mean they are claiming it can go 372 miles on the equivalent of 2.6 gallons of gas. That’s 143 MPG.

Something doesn’t wash here.

It looks nice though.

92 kilowatt-hours is the energy equivalent of 2.6 gallons of gasoline.... that is pretty darn impressive.

Lets say it's lithium ion. 720kJ/kg (lead acid is only 100kJ/kg)

Gas as you say is 3400kJ/l, 4700kJ/kg.

100 years of development in battery technology, and the smart guys who picked gasoline a century ago still have the most advance electric technology beat by a factor of 6.

Indeed, that's impressive! =-)
