I have a P85D. I'm going with two other people and a couple suitcases. My goal is to get to Vegas as quickly as possible without having to worry at all about range. Based on other threads I've seen, this is my game plan... --Set the battery limit to 100% the night before my trip. That will give me 250 miles of range to start the trip. That should be plenty to get me to Barstow without having to worry about how fast I'm going, air conditioning etc. Am I right about this? --When I get to Barstow, I was thinking of setting the charge limit a bit lower because I heard the lower the limit the faster the charge. I daily set it to 90% so I was thinking of just setting it to 90% once I get to Barstow. I figure I will eat lunch here and take a half hour break or so as it charges? ---Since the remainder of the trip is uphill and I don't want to feel any anxiety whatsoever, I was thinking of stopping at Primm before going to Vegas. Maybe letting it charge again for 20 minutes so I have plenty of miles to spare by the time I get to Vegas. --Once I'm in Vegas, I'm valeting my car at a hotel where they can charge it, so I would reset the battery limit back to 100% so for my return trip I am back to 250 miles. --On the way back, repeat the steps in reverse order. Any thoughts/comments on my gameplan? My main questions are: --is it smart to set the full battery limit the night before my trip? --am I right to bypass Rancho Cucamonga and go straight to Barstow? --am I right to set the charge limit lower when supercharging? --how much range should I have leaving Barstow where I can easily make it to Primm? --how much range should I have leaving Primm to easily make it to Vegas? --any differences on the return trip from Vegas to LA? If anyone can help me out with these questions or have any other thoughts, it would be greatly appreciated.
