40.2.1 firmware and LR RWD range decrease.

40.2.1 firmware and LR RWD range decrease.

I have a March 2019 M3 which came with 325 miles range at 100% SOC. With the 40.2.1, I see the max range I get is around 313/314 miles at 100 SOC when it was 318 /319 before the update... It has about 15000 miles on it so far. Anyone see a range decrease?

Nothing happened, your displayed range dynamically changes based on your driving and weather, this has been shown many times. As an owner of 3 Model 3s (yes 3!) I can tell you max range fluctuates all the time.

Oh no. How terrible.

I have a July 2018 built LR RWD. I have never gotten more 305 miles at 100% SOC. This is true even after the range increase to 325 miles several months ago. I have tried to calibrate the algorithm several times using different methods... I have just stopped worrying about it and I suggest you do the same.

Like me, I am assuming you are worried about your battery's health. Best thin g to do for your battery is charge it up to 70%-80% and discharged it to about 20%-30% before charging. Other than that, I would not worry about it unless there is a very large change in battery capacity.

I think Tesla needs to change it to Full, 3/4 Full, 1/2 Full, 1/4 Full and Empty. It would put a stop to all these complaints about range decreasing when all it is, is a guess-o-meter that has absolutely nothing to do with actual range.

Forgot to mention. I've noticed that when I do a long trip with multiple, consecutive charges at a superchargers the guess-o-meter seems to recalibrate. It still has nothing to do with actual range though.

I don't know what the big deal is with 100% range. A gas engine car varies as much as en EV in range based upon weather (read temperature, wind, road conditions), tire wear, load, speed, terrain, age, etc. Why would an EV be any different? I agree with gmr6415 - Tesla should just go with % and not range or should note range is 'estimated'.... I don't actually have mine set to report range in miles. I set it to report % charge instead. That is more useful to me. I just charge to 70% every day. When I go on a trip I'll charge to 90% while on trip. It just works.

Do you live in a winter state? Temperature effects the battery capacity.

In my LR RWD the estimate dropped by about 12 miles at 80/90% with 36.2.1. I haven't done a 100% charge in a long time, but the 90% range extrapolates to about 297 at 100%. No change with 40.2.1.
