Zero S is rated at 180 Wh/mile. Brammo Empulse is rated at 160 Wh/mile. Lightning claims ~120 Wh/mile.
Right off the bat, let me say that the Lightning is waaaay too much bike for me. Take my man club card away right now, but that is just wicked way too fast for my limited skills.
It is going to take me a while to get used to the liters/per 100 kilometer style of measuring energy consumption where lower numbers are better, instead of the miles/per gallon way of measuring where larger numbers are better.
I'm going to do some math pretty much just for myself (this is as good a place to keep it as anywhere) I pay 12 cents a kWh. Assuming 12K miles a year and 4 dollar premium gas:
Zero S = .18 kWh/mile * 12 cent/kWh = 2.16 cents a mile = 259 dollars/year
Empulse = .16 kWh/mile * 12 cent/kWh = 1.92 cents a mile = 230 dollars/year
Lightning = .12 kWh/mile * 12 cent/kWh = 1.44 cents a mile = 173 dollars/year
CBR250R = 70 mpg = 5.71 cents a mile = 685 dollars/year
SV650 = 48 mpg = 8.33 cents a mile = 1000 dollars/year
CBR1000RR = 35 mpg = 11.4 cents a mile = 1368 dollars/year
Honda Civic = 32 mpg = 12.5 cents a mile = 1500 dollars/year
Audi S4 = 22.5 mpg = 17.8 cents a mile = 2133 dollars/year
Lamborghini Aventador = 13 mpg = 30.8 cents a mile = 3696 dollars/year
Since I wouldn't be caught dead on a CBR250R on the road, it looks like all the other comparisons would put me significantly ahead each year.
(Of course now that I've bothered with all the math, I realized I could have just used empulsebuyer's calculator... Oh well.
