I'm only a few months into owning my Model S, and am planning to take a "big" trip to Northern California over Christmas. The only other time I've done more than local driving is when I drove the car from the Fremont Factory back to SoCal. I have a 60 with a 210 mile range. I'm mapping my Supercharger route: Total 417 miles to Sacramento (from Redondo Beach) -Stop 1 - Buttonwillow Supercharger - 131 miles -Stop 2 - Santa Nella (Pea Soup Anderson's) Supercharger - another 150 miles -Stop 3 - Sacramento (in-laws are close to a supercharger) Given that the Buttonwillow supercharger is after the Grapevine...does the Grapevine have an impact on range with the 4000+ foot climb? Or is it net neutral in the end considering the downhill toward the end? Should I plan on a Tejon Ranch stop along the way also? Thanks!
