And poorly designed. My Chevy Volt is Is a minimum of what a plug-in hybrid should be. I get 45 to 60 miles on a charge (winter-summer), and about 80% of the time, it covers a hundred percent of my driving. I think that size the batteries for plug-in hybrid depends on your usual driving patterns. Daily driving, the 50 mile range I have now is great. About twice a week I need more like 100 mile range and 2-3 times a month, we take longer weekend trips around New England.
