at least an EPA document EPA-HQ-OAR-2009-0865-0023.pdf (Environmental Protection Agency Fuel Economy Label: Literature Review) from the EPA web site appears to focus primarily on the expression 'fuel economy'.
a comparison in terms of 'fuel economy' is certainly better than comparing in terms of a pre-metric MPG that becomes less relevant to describing the energy economy of many new autos. i however don't understand why the proposed label doesn't feature an established metric comparison of fuel economy, with a measure of liter per 100 kilometer. cheers, Ron On Wed, Nov 24, 2010 at 3:13 AM, Stan Doore <[email protected]> wrote: > Rather than focus on MPG, the focus should be on cost per mile or cost per > 100 kilometers regardless of fuel. > > Stan Doore > > > > > > *From:* [email protected] [mailto:[email protected]] *On > Behalf Of *Ron Stone > *Sent:* Wednesday, November 24, 2010 3:54 AM > > *To:* U.S. Metric Association > *Cc:* U.S. Metric Association > *Subject:* [USMA:48919] new fuel economy label under review by EPA Re: Re: > Nissan Leaf > > > > a new fuel-eonomy label is under consideration by the EPA. > > > > http://www.epa.gov/fueleconomy/label.htm > > > > there is also a form to submit a comment to the EPA. > > > > Ron > > > > On Tue, Nov 23, 2010 at 11:58 PM, John Frewen-Lord <[email protected]> > wrote: > > From the link given below: > > > > "So, how does the EPA calculate mpg for an electric car?
