Smilepak. Try putting your trip and data into a trip on evtripplanner.com. After a few road trips in our car, I've found it to be quite accurate. It has settings for weight, temperature, and more importantly speed factor. I'm typically use 1.2 for the speed factor and it works out well on I5.
This thread has been helpful. I am planning to get a Tesla (lease or finance) 70D in the coming month. We tend to go up to NorCal at least a few times a year.
1) From our house to the first SC (Tejon Ranch) on the 5 freeway is approx 125 miles. Which isn't too bad, but the high mountain of the 5 and LA traffic, that might be ok
2) From that first SC to second SC (Harris Ranch) is better only 120 miles.
3) From Harris to Gilroy is 115 miles, cutting through the 152 route.
I suppose we can charge up in Fremont while we are hanging around Silicon Valley. I would think since Tesla factory is there, I would assume more SC around Silicon Valley, but Fremont is the only one ahhah.
Question: I notice you went on a trip with just two ppl. In a car of 4 let day adult and each person one luggage, how much range effect would you think or did you experience any range effect due to added weight?
This whole thread might end up making me give up certain add-on and get the 85D instead ahahha
