Everything I am reading, people are getting mid to high 200's for Wh/mi but I have had my car just 2 weeks and gotten average 325 and often much worse on a trip. This includes a 180 mile trip I took all at highway speeds where I started with over 300 mi charge and got warning I have to go less than 65 to make it home, and we had to end up hitting a supercharger. This see4ms WAY off from predictions and other's reported usage. I was using autopilot most of the way of the 180 mi trip as regular highway speeds.

I understand that quick starts and cold weather will impact the reported Wh/mi,, but this has happened with both cold (~30F) and moderate (~55F) temperatures, but this seems way out of line with even that.

Thanks for ideas.
