However, these Peugeot models seem not to be plug-in models? They are claimed to be able to start on an empty battery and (did I get this right?) charge the battery mainly from braking?
In any case, this is all window dressing as DeAnander points out. tens of millions of people stand to see their lives ruined because the bureaucrats at the ECB don't understand introductory economics -- Dean Baker
An open question is how you should measure the efficiency of various technologies. What is the MPG of a plug-in hybrid? What do you do about the different energy densities of diesel oil and gasoline? Perhaps cars should be measured in energy units rather than miles per gallon (or km per l or whatever).
