• Electricity vs. Gas

  We've assumed a fuel economy of 21 miles per gallon for a comparable gasoline powered premium sedan, for example, the 2016 Mercedes-Benz S550. We've also assumed the national average of $0.13 per kilowatt-hour for electricity, 10% charging on Tesla’s Supercharger network and $2.70 per gallon for premium gasoline over the next five years.

• Express Lane bills

  Florida has allowed owners of hybrid, electric and other low-emission vehicles to ride in high-occupancy-vehicle lanes with only one person in the car between 7 a.m. and 9 a.m. and 4 p.m. to 6 p.m. on weekdays. And with the introduction of the I-95 express lanes, they don't have to pay tolls.

• Maintanance

  EVs benefit from not requiring oil changes or other maintenance costs for exhaust systems. Studies have shown that this represents a 35 percent decrease in cost over time. Some calculations peg this to about 3 or 4 cents per mile of maintenance cost in an EV versus closer to 6 cents in an internal combustion car.
