With a plug-in hybrid I might literally have to buy gas only a few times a year.



Can Plug-In Hybrids Ride to America's Rescue?
Engineer Behind Many Electric-Car Advances Says Oil's Days May Be Numbered

Plug-in hybrids go much farther on a single charge than an ordinary hybrid. Some converted Toyota Prius plug-ins get the energy equivalent of 100 miles (or more) per gallon and travel nearly 40 miles on electricity alone before a gasoline engine kicks in for longer trips. With their hefty battery packs, such hybrids can be plugged into a socket in the evening for a charge.

Since 78 percent of American commuters drive 40 miles or less each day, a plug-in driver might need only to fill up his tank with gasoline a half-dozen times a year. It's a game-changing concept that's won over many energy-security hawks and even environmentalists who had been married to futuristic fuel-cell vehicles, but now see plug-ins as a here-and-now way to fight global warming as well as freeing the U.S. from imported oil.
