There isn’t enough thermal energy in one gallon of gasoline to move a 3500 pound vehicle 230 miles.

There isn’t enough thermal energy in one gallon of gasoline to move a 3500 pound vehicle 230 miles.

There's hardly enough to drive a 5-horsepower lawn mower around a good-sized lawn.

The 230 is a lie. A blatant, bald-faced lie.

They plugged in the car, charged the batteries, then ran a 50 mile course. 40 miles were run before the hybrid engine started to recharge the batteries and power the car.

When operating in hybrid mode, the Volt gets about 60 mpg. Pretty good, but nowhere near 230.

Any electric vehicle should have an efficiency rating based on the cost of the electricity used.

Not a round trip, but if the whole trip is from north to south, it's possible - that trip is "all downhill." Just check a globe or map if you don't believe me.
