I'm going to agree with the others that this change was different than I was expecting. The range estimate seems to be the same as it was prior to the update, but the SOC bars seem to be going down faster than they were.
I drove my car about 32 miles to the dealership, and my range estimate went from around 100 to about 65, so it was working about right for the way I was driving the car. Very flat roads all freeway with CC set to 58mph.
I had my car charged at the dealership prior to the update, and then after the update, when I picked up my car the range estimate was in the high nineties (97 I believe) and the mileage was about 35 miles driven, and when I got home after driving 31 miles the range extimate was 52 which is about right for the drive given that it looks like a little bit of charge was removed from the car before I drove it off plus about 3 miles added at the dealer. The only strange thing is that the SOC bars went down much further than I was expecting. I came off of the first bar quickly and I'm assuming this is because of the miles that the dealership put on the car testing the car after the modification. But then the SOC dropped much further on the way home that usual for this trip. In the end I lost about half my SOC in 31 miles (34 if you include the dealer miles), and normally I could drive about 45 miles before losing that much SOC at these speeds.
So the range estimate dropped appropriatly but the SOC dropped inappropriately in my view for this trip. I'll have to run a few more tests to be sure, but at this point, I'm in agreement that the change was strange.
