The distance between St Augustine and Savannah is by far the largest gap in the I 95 corridor. As an owner of a MS 60, I am very hesitant to attempt the distance. Currently I am on a trip from S Fl to Orlando, and drove my car very carefully from the PSL Supercharger to my destination at Championsgate, southwest of Orlando. The distance was 138 miles. I left the PSL SC with 190 Rate Miles, and drove the car 65 mph to see how it would do. We had 4 adults and light luggage, but the outside temp was 58 and we had a slight wind from the North that I am sure affected the miles. When I arrived I had only 38 rated miles left and averaged 328 wh/mi. I understand the efficiency and don't fault the car, but putting a 170+ hurdle for our MS 60s is a bit scary for me. Would love to drive my car to our second home in Western Mass but think I better put it on the Auto Train instead.
