We charged at four Superchargers yesterday - Gilroy, Harris Ranch, Tejon, and Barstow, all in California. It was a long day and we did have one close call. We left the Tejon Supercharger with 208 miles indicated range, drove the 137.5 miles to the Barstow Supercharger, and arrived with only 7 miles range. That means we use a theoretical 201 miles range to go only 137.5 miles. There was a mountain range crossing, and temps were in the 30's, but we don't like cutting it that close. We went with traffic or slower, generally 70 miles per hour, never over 75. The speed limit was 70.
We left Los Altos at 9:00 AM and arrived in Las Vegas at 10:30 PM. Total distance was 684 miles in 11.5 hours, so average speed with charging was almost 51 mph. That's pretty decent. However, we are averaging 403 wh/mile since Portland, far above the 325 lifetime average that we achieved with our Tesla S85 over 31k miles. This may get better now that we have broken in the tires, which supposedly get more miles per watt after 1,000 miles driven. However, we're heading into very cold country next, so I remain skeptical. The good news is that Superchargers are spaced about every 100-160 miles and we must stop because the car can't skip any chargers, so there has been on one close call as mentioned above, and that was due to a mountain climb. We don't expect any issues getting across the country about as fast as we would in a car driving on gasoline.
Yesterday J.B. Straubel posted a Tesla blog indicating that a new software upload will take advantage of our car's dual motors and ideal the bigger one at highway speeds, increasing range by 10%. That will be good, but he indicates it will come in late January, after our current adventure. No worries, but it would be nice to have more cushion on some legs. The blog post about range is here:
A few pictures, followed by a detailed chart on charges and ranges:
