Hello I have a new 2017 MS 75 I have had for about 2 months now. I tried to keep track of the range for each charge as I mainly do the same commute every day: 37 miles each way for a total of 77 miles. In the morning, I average about 75mph and going home I average about 30 (rush hour). It has been around 90 degrees here, so I keep the air on. I try not to mash the accelerator and drive pretty normal. During that time, my 90% would read at about 260, and after one round trip of 77.7 miles, my estimated range would be around 155. Does that seem correct? It is almost double the miles of range gone than actual miles traveled. Any advice would be appreciated.
