I thought it too difficult to compare the ecars, so I collected the bare facts and compiled them for easy comparison.
Many are "Hybrids", meaning they have a gas engine also. MPG comparison is based solely on electric from batteries. KWH is based on $.10 per kwh.
m/kwh - Miles Per Kilowatt hour
eMPG - electric cost, to gas cost, per mile comparison, (based on gas @ $3/gallon)
---------------------------------
1000w Air Conditioner
or ... 1000w Heater
168kwh per week
720kwh per month
---------------------------------
Why the air conditioner stats?
In order to demonstrate how little increased electric demand will be required by converting to electric vehicles.
For example: The BMW Mini E, can be fully charged 20+ times and driven more than 3000 miles, (coast to coast!), with the electricity used, in 1 month, by a small size, window, air conditioner, or small 1000w heater!
Some claim that the electrical grid and electrical production will require major upgrading, to accommodate electric cars.
Actually, electrical production is reduced by about 50%, every night.
Electric companies even offer 1/2 price electricity for these "off peak" hours.
If every car was replaced by electric, and timed to be charged in these "off peak" hours, the total grid usage would still be less than the daytime usage!
Yes, these timers are readily available, some ecars even have the function "built-in."

The Hybrids tend to have much lower efficiency due to having to drag around a gas motor, drive train, gas tank etc.
Please note: using electric heater - air conditioner will decrease mileage noticeably!
While eMPG is impressive, in most areas, a "smart meter" can be installed. When charged at night during "off peak" hours, electricity can be as low as 1/2 the cost. Which would effectively double the eMPG, effectively giving, some of the ecars, in excess of 300 eMPG!!!
