40.4 here and I think there has been some improvement. I wouldn’t say it’s “grabbier” as far as the feeling of g-forces go, but I did notice when I was driving last night that I was consistently coming to a stop sooner than I had gotten used to. So maybe it’s back to being a bit more aggressive now, but still operates very smoothly as in the recent past.
As an aside, I wasn’t aware of any potential change to regen with 40.3/40.4 so I didn’t have the possibility of being affected by a placebo effect. That said, I had not driven the car for about a week until last night and it’s possible that also contributed to
misjudging stopping distances to some extent. That’s why I began my post with “I think.”
