The writer missed a couple important points.   The Chevy Volt is not a standard hybrid vehicle, it a PHEV (Plug-in Hybrid electric Vehicle).   After the 53 mile electric range it will go approximately 360 miles on gasoline.   Many Volt owners run as an Electric Vehicle commuting and around town, and as a "gas car" on their weekend trips to the mountains.  The other issue important for Colorado residents is that any new car purchased that "plugs in" provides the buyer a $5000 state rebate.   Colorado has the best state level incentives in the country for EVs.
