Tesla now recommends Model 3 charging to 90% for normal driving (especially in the winter!). If you have been charging to a lower level for your daily driving, continue charging to 90% to help the BMS re-calibrate over a period of three or four charges and it will start charge-completion to your setting of 90%.

Tesla Dual Motor cars are rear biased. The rear motor does most of the work, that's why you'd notice the back end kicking out sometimes. Most people don't realize this. Depending on what models your previous AWD cars were, they might have been front wheel drive biased and send power to the rear when necessary.
Usually only higher end AWD cars are rear wheel biased for performance reasons.

I dont... i just bought another house... and am in the middle of a reno at the new place.. it has garages.. lol part of the reason i bought it... i held off installing the wall charger at my current house... cause i figured id be buying a bigger place and figured id save the cash..
I use percentage of energy left instead of distance. I find it more accurate.
In summer, I would multiple it by 5; in mild winter by 3; this weekend, it is 2. Doing so, will give me a much better idea of how far I can go.
But man, the Grimsby Supercharger is the best I have seen. It was charging at over 700 km/hr compared to may be 300 km/hr in Markville mall. I think both of them are rated at 175 kw. There are nobody sharing the charger with me in both cases.

I know. The problem is SO is the last person that you want to give anxiety to. They will say you spend so much money on M3 and we have to worry about battery level; we don't have that kind of problem with ICE.
Another reason why I still keep my ICE for the time being... To cold, not enough juice in M3, just drive ICE.
Tony has this right - we owned both a Audi S4 (with the Sport differential) and Acura TLX (SH-AWD). I was initially shocked at the rear end giving out on the S4 (first time with AWD) with winter tires on. I had to manually change it the non-sport setting in order to minimize the rear end fish tail. The Acura on the other hand just goes with little drama - but that is FWD bias while the Audi was RWD bias. Big difference in how they tackle road conditions.

Hmmm I wonder if its a calibration issue? I started to charge at 90% from 80% around Nov, but noticed the car rarely stops its charge at 90%, completes at 89% even though the app is set to 90% (below the trip range indicators).

Exactly, perfect examples. Which is why even the Dual Motor Tesla's aren't infallible to the rear end kicking out. They may correct a split second sooner than the RWD cars but it can still happen.
Same thing happens to mine, set to charge at 90% daily and it completes with 89%. Sometimes it shows 90%, not sure what's up.
As part of the battery re-calibration, Tesla also wants us to charge to 100% every now and then, on top of the normal 90% charge for daily driving, which should clear up this issue, as it did mine.

I have the car charging now while at work. Will let it juice up to 100% and see how it goes. Been about 2 months since I last charge it to 100%, but that was at a supercharger.

I've never waited for a full 100%, takes too long. Anything above 95% should give you a good recalibration.
The front motor is smaller than the rear one. Maybe that’s why it’s rear biased. However we are looking at a disruptive ev design... there is mechanical torque distribution system other than two individually computerized motors.

It's rear biased on all the Tesla's with dual motors. Not all Models have a larger rear motor, with the S & X only the Performance models have a larger rear motor. The front motors engage for efficiency purposes, acceleration and stability to name a few. The rear motor does most of the work.

^ This. I found a tip on Reddit that suggested creating a new driver profile named Snow (or whatever works) and setting Acceleration to Chill and Battery Regen to Low. I also set Creep to Off on mine. Whenever the roads get bad, just switch profiles.
I didn't know the driver profiles saved all these settings, I thought it was just seats and mirrors, so it was a TIL thing.
As for range, it's been pretty miserable the last couple of days. I stayed home most of the weekend due to the cold, but Saturday I drove 13 Km with 42% efficiency, and Sunday I drove 19 Km with 48% efficiency. But, it's only 3-4 months that we have to deal with this, then it'll warm up.
