Impressive savings!Had to whip out the calculator function on the 'puter:
84 mile round trip x 6 days a week (average 600 hrs of overtime per year) @ 18 mpg [diesel] = 1456 gallons per year.
With an Elio, assuming 84mpg, I'd be using 312 gallons per year over the same distance with a fuel usage drop of 1144 gallons per year.
I'm literally all highway from within 1/2 mile of my house, to where I-170 dumps into Boeings east parking lot.
