How to rate gas mileage when no gas is used

Can a car truly break the 150 miles per gallon (MPG) mark? Well, it can if it's this company which heavily modified a Saturn VUE Hybrid. The company, AFS Trinity, also claims that they are being "muzzled" by the dark shadowy figures behind the L.A. Auto Show who are in the pockets of Big Auto.

The problem lies in their 150 mpg claim. No, the vehicle, a plug-in electric hybrid, barely uses gas but instead derives its power from electricity. Of course if your vehicle doesn't use gas as its main source of power, your MPG rating will be off the charts. The sticky part of this math is that the average consumer is still beholden to the almight MPG rating because, well, we really aren't used to having a Plan-B.

Instead, tout how far it can go on a trip per charge. Break that down to a cost per mile driven based on the average price of electricity. Convert that to the average cost for driving 15,000 miles per years and compare that with a few different gas prices such as $2.00, $3.00 and $4.00/gallon and let people draw their own conclusion.
