I use carbon emissions here, not because I believe them to be especially important, but because 1) they are easy to work with, and 2) others (govts) think they are important.
Fuel facts :
U.S. average equals roughly 22 ounces CO2 per kWhr of electric power consumed (net, at the wall).
Gasoline combustion in a modern fuel injected engine produces roughly 310 ounces of CO2 per gallon.
Car facts :
The Tesla Model S gets roughly 2.4 miles per kWhr, town, 2 miles per kWhr Interstate highway travel, due to the fact that its 85 kWhr battery requires 100 kWhrs of electricity to fully charge (15% loss due to heating), and highway range averages roughly 200 miles and around-town averages roughly 240 miles.
The Elio gets 49 mpg city, 84 mpg highway.
Conclusions:
The Tesla Model S is responsible for 9.1 ounces CO2 per mile, town, 11 ounces per mile Interstate highway.
The Elio emits 6.3 ounces CO2 per mile town, 3.7 ounces per mile highway.
The Tesla produces more than three times the carbon emissions than the Elio on the highway, and at least 50% more around town.
These are actually optimistic figures for the Tesla, since it uses electricity at all times to maintain the temperature of its water cooled battery pack. There is also an unknown (but small) amount of
battery leakage, or loss of charge over time.
In terms of oil consumption,the Tesla can eliminate all of the oil consumed as gasoline by the car it replaces, while the Elio can eliminate half of the average car's gasoline consumption, since it
gets at least twice the mileage of the (average) car it replaces.
The Tesla Model S receives large Federal and state subsidies : $7500 tax break from the Feds, and a sliding amount from California,which forces automakers who are not producing electric cars to pay Tesla for each car it produces.
Results on a per dollar spent basis.
The above results are on a car-to-car basis. But govt subsidies have a goal of emission reduction and it is appropriate to judge their effect, not on a car to car basis, but on a dollar spent basis - how much emission reduction will result from each dollar spent subsidizing an Elio versus a Tesla Model S?
The Elio we will assume costs $7000. The Tesla Model S we know costs between $77,000 and well over a $100,000, so let's say the Tesla costs between 11 and 15 times more than an Elio. Therefore,for each dollar of subsidy, the govt can achieve 33 to 45 times more carbon emission reductions, highway,and between 6 and 8 times more, city, and 5.5 to 7.5 times greater oil reductions subsidizing Elio cars instead of Tesla Model S vehicles.
The govts also allow Tesla owners to avoid all road taxes, despite the fact that their cars(4700 pounds) will probably inflict four times the damage to our roads than the 1200 pound Elio.
