Does ver 9 affect drive efficiency?

[Silver Ghost]

I drive about 80 miles to work. Usually I drive at 80 mph on TACC. Usually my battery goes from 90% SOC to 55% by the time I reach work. Today (day 1 with ver 9) it went from 90 to 45% SOC. Noticed 2 difference 1) had a cold front come through and tire pressure dropped from 46 psi to 40 psi. 2) the rain was heavy enough that there was some standing water on I-35. Are these two differences enough to explain the change or is there more to it? Specifically did anyone else notice this ?

1) had a cold front come through and tire pressure dropped from 46 psi to 40 psi.

There’s your likely culprit right there. Not so much the lower tire pressure, but if it got colder where you are then that would negatively affect battery performance and reduce your range.

P3D with V9 - more efficient?
