Combined city/highway mileage: 112 mpge Mitsubishi's i-MiEV is technically a 2012, but the automaker is carrying it into 2013 unchanged -- with the best fuel economy of any mass-produced car on the U.S. market and one of the lowest prices for an electric. The small four-door hatchback starts at just $29,125, which is $10,000 or more below the price for all other mainstream electric cars except the recently discounted Nissan Leaf. Of course, the i-MiEV has a low price partly because the vehicle has a relatively small cabin, a 66-horsepower electric motor and just a 62-mile range between battery charges. The Mitsubishi also needs around seven hours to fully recharge at 240 volts -- about twice what it takes to juice up a Chevy Volt, Ford Focus BEV or the fastest-charging Nissan Leafs. Mitsubishi won't say whether it plans update the car later in 2013.
