Second-worst flop of the decade: Mitsubishi i-MiEV
Sales: 1,420 (2011-present)
The all-electric Mitsubishi i-MiEV offers one of the highest fuel-efficiency ratings of any mainstream 2013, but Takahashi calls it "a porta-potty on wheels.""It seems like the whole car is made out of really bad plastic," he says. Technically a 2012 but still available on dealers' lots, the tiny four-door hatchback gets the electric-car equivalent of 126 mpg/city and 99 mpg/highway. But the i-MiEV manages such great numbers only by having a small cabin, a 66-horsepower electric motor and batteries that need recharging after just 62 miles (meaning the car can only make a 31-mile round trip). The Mitsubishi also requires about seven hours to fully recharge at 240 volts. That's roughly twice as long as what some rival electric cars need to juice up.
