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Does this mean the other shoe will drop regarding the outdated miles per gallon measurement?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.
