for a total distance of about 2800km, following HWY 1 route which has all the necessary superchargers. The car lifelong average is 238 Wh/km, which is from Sept.2014 to today. Living and driving daily through an Edmonton winter. The other thing to report is that it is not necessary for 100% range charging anywhere on this route if driving a 85 battery. ..that's with the trip temperatures between -2 to +10C typically... and at no time was battery warming cycle triggered by cold temperatures at first start up for the day. We used cabin heating as required for comfort, and little shots of A/C to clear interior window fogging due to humidity near the coast on rainy / coldish days. On the way to Vancouver I drove moderately, stayed at or under the speed limit. After learning range is no problem between any two SC I drove, er uhm, less moderately on the way back. Passing anything you want whilst going uphill on a long steep mountain pass is awesome. Push the pedal and zoom you're by any obstacle. Suggestion: Give your kid in the back a wireless USB mouse and plug it in, and have them use the web browser to pre-visit each upcoming town on wikipedia and read out interesting facts. Turns a ride into a narrated tour! We actually made stops and sought things out in towns, even if SC was not there to charge up.
