Hi, I'm new to Tesla overall, and my model s is getting work done at the service center and I got a signature P90X loaner. It sure is an upgrade. However, I've been quite anxious about the range on this car since I got it about a month ago. We live in tha Bay Area and we took a day trip yesterday that totaled 152 miles and at the end of the trip there's 27 miles of range in the battery. We had charged the battery to full the night before at 242 miles. It looks like the car probably would have gotten around 170 out of the suggested 242 miles had we run it until it was empty. The weather was in the mid 80's. The trip was mostly freeway with 4 normal sized adults (avg weight 150lbs)and 2 toddlers with minimal cargo. Yes AC was on at the lowest temp and fan speed mostly at 4. I drove quite conservatively at avg speed of 72. AP was off pretty much the whole time. So my question is is that considered normal? For it to have only 170 miles out of the battery? Again, I'd not had my model s long enough to have comparable date but 170 seems very low to me given the driving condition. A couple weeks ago, we had another scare where we were about 2 miles away from home and the battery indicated we had 8 miles left. So I kept driving on the freeway at 65 with only my wife and one kid. By the time we got home, it had gone past 0. Would love to hear your thoughts and experience. Thanks.
