Having driven 620 miles on my Karma, I decided to look at its cost per mile and compare it to my prior daily drivers. About 40% of my driving is on the freeway and 60% around town. 2/3 of the days I drive less than 30 miles and don't use the ICE.
With premium gasoline at $3.93/gal. and electricity at $.20/kwh in California, my cost is $.18/mile. Under the same driving conditions that compares with previous daily drivers:
2006 BMW M5 (12 mpg) - $.33/mile
2008 Lexus LS600 hybrid (17 mpg) - $.23
Plugging in the national averages for gasoline ($3.65) and electricity ($.115), my cost could have been $.135/mile.
Conclusions:
1) Hybrids are cheaper to operate, especially PHEV's
2) California is expensive
3) Your costs and mileage may vary
4) I'm a nerd
