How Tesla Cars Work
The motor converts electricity into mechanical power and also acts as a generator, turning mechanical power into electricity.
When the accelerator pedal is released, the motor switches to ‘generator’ mode and captures energy while slowing the car.

3. Fuel efficiency compared to normal cars
Equivalent of 87 miles per gallon1
Up to 265 miles on single battery charge1
85 kilowatt battery1
Equivalent of less than 3 gallons of gas1
At best, only 30% of the energy stored in gasoline is converted to forward motion. The rest is wasted as heat and noise.2
Honda Civic--“EPA-rated at 51 mpg for combined city and highway driving.”2

5. Carbon emissions of Electric cars compared to normal cars
Directly relates to power grid automobile is charging from1
Ohio, Virginia, Kentucky, Indiana (grids run off coal)--higher CO2 emissions1
California (natural gas)--lower CO2 emissions1
No tailpipe emissions1

7. Why use tesla Cars
Consumer Reports rating of 103/100 for Model S P85D2
“The more you drive it, the greener it becomes.”3
electricity costs about $0.06 for one kilowatt hour (kWh). To charge a car like the Nissan Leaf, with a 24 kWh battery, it would cost $1.44—to go 100 miles1
To go 100 miles in an internal combustion car, like the Nissan Altima, it would cost about $14.25 in gasoline.1

8. Cons of Tesla’s Battery requires charging1 Very pricey
The cost of a Tesla Model S can range from $70,000 to $138,0001
Charging inefficiency
The "peak charging efficiency" of Tesla cars is 92%3
Vampire losses2
Energy wasted when the car is off2
Requires more energy to construct Tesla automobiles than a typical sedan3
