God damnit, i was looking to spend $42,000 on a car so i could save money on gas.
Good question
So at what point does an electric car become economical?
Let's assume a Volt like car costs $42,000 and an equivalent gas powered car costs $22,000 and gets 40 mpg.
Let's also assume future homes have solar powered charging stations. Assume you drive 280 miles a week or 7 gallons a week
If gas costs $4 a gallon you pay $1456 a year or $14,560 over ten years
If gas costs $5 a gallon, you pay $1820 a year or $18,200 over ten years
So break even is $5.50 A gallon
As long as gas companies keep gas under $5.50 they can keep electric cars off the market
