I would love to see a non plug in Hybrid. I have a RAV4 Hybrid and get 40MPG without ever having to worry about plugging it in.
If you live in a densely populated city without permanent assigned parking, an apartment or condo, an old house, travel for days at a time or in the sparsely populated areas of the country the plug in option is severely limited, thereby reducing its functional value to that of a mere novelty.
If they do go with an old school hybrid it would be beneficial to increase the battery size and improve the chemistry. My battery never seems to get me out of the parking lot before the systems jumps out of electric only mode. I have not driven the new Jeep 4xe, but it looks promising on several levels...aside from the ridiculous price and weak overall fuel economy.
It would be interesting to see if the Boxer can be optimized to run a hybrid setup.
