EPA Admits New Mileage Calculations Needed for EVs

A few weeks ago we wrote how no one was happy with the EPA’s calculations for measuring the mileage of plug-in and electric vehicles. With the EPA’s equation, GM came up with 230 mpg for the Volt and Nissan got 367 mpg for its all-electric Leaf.

In response to these pressures and a proposal from Israel’s ETV Motors, the EPA released a letter admitting its measurements need adjustment.

The letter said the agency would, “initiate a new rule-making to explore in detail the information displayed on the current fuel economy label and the methodology for deriving that information.”

It also wants input on new consumer labels that will provide all the necessary information for drivers to make good decisions.

Does this mean the other shoe will drop regarding the outdated miles per gallon measurement? It’s too soon to tell, and what shape the EPA’s “adjustment factors” take is still completely up in the air.

They should just do it like every other car but do it after like 40 miles (or whenever the batteries run down) so its like "Infinity miles per gallon up till 40 miles then its like 40mpg after that" or something like that.

I hope some companies would make electric cars more cheaper than gasoline engine vehicles.

1. The cost of running the vehicle should be 1 to 2 cents per mile, compared to 10 cents or more per mile to run a gas car.

2. How Can An Electric Car Travel 100 Miles For $1?

3. Applied to a different methodology from DOE formula, the notable EVs suffice to reach 200 to 300 MPG .

4. The vehicle-to-grid communication technology is helping the battery serve as a storage to prevent the costly blackout standing at about $90 to 100bn per year. That means utilities are shedding cost for additional storage facilities and ratepayers are selling electricity during peak demand so that EVs can make more economic sense, as we know.

5. Electric vehicles require little maintenance -- no oil changes, for instance --. Better still, they can charge at the stores offering charge service.

Hey,
I recently came accross your blog and have been reading along. I thought I would leave my first comment. I dont know what to say except that I have enjoyed reading. Nice blog. I will keep visiting this blog very often.
