Lower range after E445 major upgrade??
I’m not sure if it’s my imagination but it seems like I’m getting worse range now than prior to the E445 update. For example when starting out in my garage and a few miles thereafter, I see numbers like 970 wh/mile. It does eventually come down 400 or even in the mid to upper 300s Wh/mile but I don’t recall seeing numbers so high. Temperatures have been rather mild (40s, 50s, and even some low 60s). Yesterday, after I charged the car to 90% with a range of 361 miles, I drove for about 80 miles and the remaining range dropped to 240. Temps were in the upper 50s and dropped to the 40s for the last 35 miles.
Am I imagining this or is it a problem after the major MBUX update? What have you folks experienced?

Btw, why doesn’t the inside temperature setting say ECO++ any more? Is this due to the E445 MBUX update? I did set it to ECO on the EQ menu.

Are there any other new changes result of the new software upgrade to E445? Things such as self (auto) lane change or new games or apps in mbux?
As far as new games or apps is concerned, I’m not sure since I never play games.
BTW, today was an amazingly warm day here for this time of year (mid to upper 60s). My range increased a lot.

Today, in my local newspaper, there was an article about the efforts to unclog a kilometers-long stretch of 4-lane highway from cars stranded there for up to 22 hours during a blizzard event in my region. People idling forever in ICE vehicles fared well enough. People in EV's, fared less-well. Not a surprise either -- but it brings into sharp focus the extra planning one should do when taking extended trips if there is even the slightest possibility of extreme weather.
The article also discussed typically "overly-optimistic" EV range marketing in general (i.e. range estimates are provided at optimal temps and generally not even with an asterisk referring the reader to impossible-to-read text explaining such). The article went on to mention that Norway has apparently been doing some extensive studies on this across multiple brands/types of EV's and the general finding is a 20-40% reduction in range when operating in sub-freezing temperatures. Of course, "sub-freezing" can mean something really extreme in Norway and I have no knowledge of the details behind this study and the temperature ranges they were using. It makes on wonder if there is a temperature beyond which it would be dangerous in some way to use an EV at all.
