Hello everyone, this is my first post here. My father just ordered an S and I have been following the progress of Tesla Motors with great interest over the past few years.
I have a question about how much more quickly Rated Range declines when ascending long grades, such as the western slopes of the Sierra Nevada mountains from the California Central Valley floor to Tioga Pass, compared to driving an equivalent distance on the flats, and if there is in fact a more rapid loss of range going uphill is there a corresponding conservation of Rated Range when making long descents due to regeneration?
I live in the San Francisco Bay Area. My wife and I like to take trips to the mountains and based on the map at http://www.teslamotors.com/supercharger of Supercharger stations that are being built out over the next couple of years, the closest station to the Sierra Nevada mountains on the west side is at Folsom, just east of Sacramento. A charge at that station will get an S85 to the South Lake Tahoe area and back, but it won't make it to the Yosemite / Sequoia area. Many of the places we stay at in the mountains do not yet offer a 240V outlet to their guests. We also like to go car camping where electrical outlets are even scarcer.
Currently we take our 2008 Prius on long trips, and from our house to the mountains and back typically average about 45mpg.
It is interesting to note on the Supercharger station map that it appears that no stations are planned to be built in the next 2+ years along Hwy 99 in the Central Valley. That is disappointing, as a station in the Merced/Fresno area would be well placed to support drives into the central Sierra Nevada mountains. The map does show a future station slightly east of the Bay Area and south of Sacramento but the map has so little detail that I can't determine where it will be located.
