Try running that case at 70 or 80% of the speed limit and see what it gets you. Slowing down usually helps a lot with range when you need it...
Good point I lowered the speed to 80% on some of the parameters that had me routing for a stop at the SC and it changed them to the 7-10% range upon arrival so yeah should be able to work around it even in the worst of weather.
Update: My sales advisor just did email me back that yes the LR RWD can be special ordered still off menu. No word about how long they take to make those but claims they are available now to order through him. Decisions, decisions,
Not sure if I can order the LR RWD with no AP, I may ask that to lower my initial cost and then spring for the AP later.
I believe the LR RWD has the full Premium Interior option so better than the SR+ interior ; it also would give me 120,000 mile battery/drive train warranty instead of 100K which is worth noting.
