You all remember the weird 230 mpg number touted by GM for Volt and the bad press that garnered.
http://scienceblogs.com/goodmath/2009/08/the_chevy_volt_gets_230_mpg_on.php
So, here is the new method of calculating mpg devised by Argonne National Laboratory. Or rather announcement that the new method has been finalized - since the method is not available freely. They are also working on mpge method for EVs.

Mike Duoba, a principal mechanical engineer at the U.S. Department of Energy's Argonne National Laboratory, and his colleagues are celebrating the recent approval of SAE J1711, the revised recommended practice for figuring out the fuel economy and exhaust emissions test procedures of hybrid and plug-in hybrid vehicles (PHEVs).

With the completion of SAE J1711, Duoba and his colleagues are now focused on supporting the development of testing standards for all-electric vehicles, known as SAE J1634. The development of this standard may be finished by year's end, with voting by SAE members to take place shortly thereafter, he said.
