Looking for some advice...I'm new to the EV world. I just picked a 2015 SL w 1700 miles on it. I work at sea level and live at 2980 feet. The commute is 52 miles along a windy coastal road. The first 42 miles cover 1400 ft of elevation. The last 10 miles is 1580 ft climb. I leave work with a full charge and get to the 42 mile mark with about 30miles of range indicated. The last ten miles zaps the range and I pull into my drive with my low battery light chiming. Any tips and suggestions on how to better my range for my commute?
