~15% reduction in range after v7 update on S85

[anselor]

Is anyone else experiencing this? The v7 update installed last night.
I typically get around 280Wh/mi driving around town. Today I was getting around 320Wh/mi.

No problems here. I typically get around 330Wh/mi in my P85/21", today with v7 I got 295Wh/mi over 39mi. Probably need to gather more data before jumping before jumping to conclusions. So many factors can affect range, from day to day and trip to trip.

My efficiency seems to be slightly better, but as said before, way too small of a sample size at this point to say much. Anselor, has the weather changed a lot for you lately, could that be a factor?

 

[Odenator]

Nope, my "classic" P85 w/ v7.0 is significantly more efficent than before.

I seem more efficient than before , 330 down to 290. Not sure what is going on

My efficiency hasn't changed noticeably with 7.0; it's been hovering around 300 Wh/mi all summer. I watch it pretty carefully and would have noticed a +/-10% swing.

Mine went from 330 average. To 270

I don't know where you're located, but if you're on the east coast of the US it became much cooler this weekend. Keep in mind the car will use more energy for pack and cabin heating.

I too have noticed a significant decrease in wh/mi. This was yesterday and the temp was in the high 50's. This is on a P85D.

Sudden shift to cooler nighttime/morning temps below 50 has a noticeable impact on range, as the battery needs to be warmed in the morning. I remember being surprised by this two years ago. Best way to address is to time your charging to wrap up just before you drive the car in the morning, so the battery warms up on shore power. I start my 80a HPWC at 5:45.

I'm in Florida so, while there has been a temperature drop, it was down to the lower 70's. I don't think it's a temperature related issue.

I'm going to try a few more controlled experiments today and record consumption at varying speeds.

Mine is quite a bit worse but I also installed the winter tires so I can't, with any honesty, blame v7.

So, I have been giving consideration to putting on snow tires (here in New England). You find it necessary to put them on in TX?
Last year (on a P85) I drove on the all season and thought it was okay.

Mine dropped, but it's not due to v7. It dropped last week when it got cold on my daily commute (still on 6.2).

Also, last trip outdoor temp was 75-80F (6.2), this trip 45-50F (first trip with v7). Obviously range took a hit.

So I'm sure it's not v7 for me.
