Tesla updated the Supercharger map again this morning and it now appears that all of the major gaps on the east coast (Savannah,Georgia) and the biggest cross country (Macedonia, OH, Wyoming) have been filled and it is now theoretically possible to drive a Tesla from Vancouver BC to San Diego California to Boston Massachusetts down to Miami Florida. Theoretically…if you are very easy on the accelerator.
Tesla hasn’t officially announced the milestone yet because that 302 mile Wyoming-Colorado jump is probably too big to drive without some range extending mode happening. The imminent Cheyenne, WY station should cut this to 164 miles. Also the altitude climb here is significant.
Tesla’s Q4 financial results, where they are also expected to announce the battery giga-factory would be a good time to mention the transcontinental super(charger)highway. Tesla CEO Elon Musk is going to ride across the country with his 5 kids in March so there’s still lots of time to fill those gaps.
Maps of the 3 biggest cross country and two biggest East Coast gaps, below (or if you want to map out future stations which close these gaps, check out the TeslaWiki):
As for the East Coast, the biggest gaps are: the Newark Delaware-> VA which is 198 miles.
