The NEDC "combined and weighted" mpg estimate is very sensitive to battery range which is why the Volt scores so well. I saw someone claim that the Plugin Prius would get a NEDC estimate of around 134 but I don't know how accurate that is. In general, NEDC test cycles are easy and result in higher estimates than the EPA numbers. For example, the NEDC estimates battery range of the Volt is 51.6 miles but the EPA range is 35.
