Nissan Leaf gets 99 MPG with no gas tank
Giving a vehicle that uses no gas a MPG rating is less confusing?

EVs are big news today and there are two high-profile vehicles that use electricity coming to the market in the U.S. very soon. The Nissan Leaf is a pure EV with no emissions and no tail pipe. The Chevy Volt is a more confusing animal with a gasoline engine that charges the battery pack in the car when the electric motor can no longer run alone.

The Leaf has been granted its EPA fuel efficiency label and that's where things get confusing. The EPA was looking for a way to allow consumers to compare EVs to traditional vehicles that use the miles per gallon rating so they concocted a formula that applies a MPG rating to vehicles like the Leaf that use no gasoline.

The EPA figures that 33.7 kilowatt hours of electricity is equal to a gallon of gasoline and bases their formula off that number. The official EPA number for the Leaf is 99 miles to a gallon. That number is reached by combining the 106 MPG rating in city driving with the 92 MPG on the highway rating. That is impressive and may be perfect for some drivers. However, many drivers will be concerned about the low driving range for the vehicle. Nissan has long touted that the Leaf will go for 100 miles on a single charge. The EPA put the Leaf through five different tests to simulate different driving situations to arrive at its driving range.

The EPA pegs the Leaf for 73 miles on a fully charged battery. Many factors could change that driving distance though from temperature to how much the AC and other accessories are used. To confuse things even more, on the window of the Leaf the FTC will have a sticker that displays the driving range of the car at 96 to 110 miles on a full charge. 

That means that the Leaf will wear stickers that show an EPA rating for 99 MPG despite the fact it has no fuel, an FTC sticker showing 96 to 110 miles per charge, Nissan's long-touted 100-mile driving range, and the EPA 73 miles per charge number. Oddly, all of these stickers claim the common goal of making it easier for EV shoppers to tell how they equate to other EVs and traditional vehicles as well as hybrids. The EPA figures the Leaf will cost about $561 in electricity yearly.

"We're pleased the label clearly demonstrates the Nissan LEAF to be a best-in-class option, reflecting that it's a pure electric vehicle, uses no gas, has no tailpipe and has zero emissions," said Scott Becker, senior vice president, Finance and Administration, Nissan Americas. "The label provides consumers with a tool to compare alternative-fuel vehicles to those with a traditional internal combustion engine and allows them to make an informed purchase decision."

In Theory

If a car does not have a gas engine and all the accompanying baggage, you are theoretically saving around $5000, if not much more. Solution: buy the cheapest possible ZEV with its limited range, and then rent a car for longer trips. The question is, how many times a year could you rent a car from the money you saved by buying a car with no gas engine or other extended range option? And would that be enough? Assuming you saved $5000 by nixing the gas engine, then over the course of 10 years you could rent a car about 10 days a year. Or more if you get weekend specials.

Why do you think that you'd save $5000 if you left out the engine? You'd still have to propel the car with something and I don't think that an electric motor + batteries + electricity will be as cheap as the gasoline engine + gasoline.
