You’re not saving any money whatsoever – at $46,000, the difference between the Volt and a Civic/Corolla/Sentra/any other comparably sized gasoline engine car in gas mileage is negligible. Even with gas at $4 a gallon and and an annual commute of 20,000 miles, the gasoline-only car getting 25 MPG would cost you $3200 for the year. Even if the Volt were 100% free, it would still take almost 10 years of driving to offset the cost differential.
There will always be people who spend the extra to feel good about what they’re doing to save the earth or whatever, but until these things become reasonable in a way that can be substantiated by mathematics, they’re not going to go mainstream.
I previously wrote When it’s financially better than the alternatives it will catch on…and not until and If people wanted cars with great mileage, they’d be buying them about this issue.
I hope we keep making headway on alternative fuels and hybrids and Mr. Fusion, but a lot of people seem to ignore reality when they push some of this stuff.
