Yup. I set it up in the tool. Here is a link to my settings.

http://ecomodder.com/forum/tool-aero-rolling-resistance.php?Weight=1928&WeightUnits=lbs&CRR=.02 &Cd=.5&FrontalArea=1.54&FrontalAreaUnits=m^2&FuelW h=33557&IceEfficiency=.8&DrivetrainEfficiency=.98& ParasiticOverhead=240&rho=1.225&FromToStep=5-200-5

It doesn't agree very well with the actual wh/mi I am getting, but obviously some of the entries are simply a swag. I made the tires higher rolling resistance than normal car tires, but maybe it's not high enough?

The calculator says I should be getting around 150 mpg equiv at 50 mph, which is in the vicinity I had initially hoped for. My Saturn EV was around 140 and weighed 1000 lbs more!

First off, I'd recommend starting a "fuel economy" log, because maybe - hopefully? - that one-off measurement will turn out to be an outlier. (You can enter & track kWh units in this site's fuel log tool, btw.)
