Took first road trip yesterday. Car worked great. Comfortable and lots of room for stuff. Tire pressure set to 45 psi cold. Starting charge at 100%. Said 345 rated miles. Excellent! Charged for 90 to 100 times to unplug right when we had to leave. Drove 90 miles. Finish rated miles was 227. 118 rated miles used. Trip consumption was constantly falling below prediction. Ran speed limit +5 entire way. Mostly in TACC Figured it was the speed. But evtripplanner says I should have used 86 rated miles. I put in 1.1 speed in evtripplanner. And I selected a P100D which should be worse? See attached ev trip planner output. What is realistic? I was hoping I could do this round trip with no charging. Including a bit of driving around for the weekend. Looks like at minimum I'm going to have to find a supercharger in the way home.
