The Fit EV consumes just 29 kWh of electricity per 100 miles driven, which will cost the average driver about $500 per year. The EPA's MPGe rating is determined based on the energy present in a gallon of gasoline and converting it from BTUs to kWh -- which comes out to 33.7 kWh of electricity. Otherwise, the simulated highway and city driving dynamometer tests required by the EPA are the same for EVs and cars that run on gasoline or diesel. In addition to its miserliness, the Fit EV's 20 kWh lithium-ion battery pack also gives it a decent total range -- 82 miles, according to the EPA's combined city and highway test cycle. That's nine more miles than the Leaf and a full 20 more miles than the i-MiEV. It's also six more miles than Honda told us the Fit EV would achieve in mixed driving when they unveiled the car at the LA Auto Show last November. With its 6.6 kW charger instead of the 3.3 kW unit that most EVs use, the Fit EV also promises a full
