http://www.consumerreports.org/cro/2012/05/best-worst-fuel-economy/index.htm Sorry if you have seen this list already. It is from January, but I only stumbled on it today. The Energi did not make the list at all. The Max did, but with their own MPG figures, as with all the cars they mentioned. The Volt was also there but I didn't see the PIP. Not sure why Chevy got better representation than the Energi, which is more efficient than the Volt in both EV (albeit for about half the range) and gas (for about twice the range) or PIP, which is more efficient as a hybrid than the others. I guess they never got their hands on the Energi and PIP.
