Are you checking from your phone?
For some reason, it does not show up on the mobile site for me either but when I open it up on my laptop/ desktop, it shows the delivery estimate. Might want to give it a shot to see if it appears there.
So what do people think... are the new acceleration numbers actually a boost or are they just Tesla catching up on updating their official times because the cars have been beating those old times for awhile...
To me it’s catching up. After 2-3 power increases they haven’t updated their site. Total marketing. The new car will not have the new cells. DU are the same. Only thing mechanically different is the heat pump which gives better range in cold climates only.
Acceleration numbers are just updated to reflect reality. The cars have been running these acceleration times for a while now. You will not see/feel any difference in acceleration.
Tesla has been overachieving its numbers, now they are just taking credit for that.

Don't listen to him. If you use the heater smart you can have almost summer consumption in near 0C.
What you must do - turn the seat heater on 5 minutes before going in and start preheating. Not more than 5 minutes. Then go inside, drive, and in about 10 minutes turn on heater, but not on Auto because it turns on AC which first cools off the canin then heats it(don't ask why) - turn heater on, AC off, manual to 2. That's it. I have managed 130Wh/km or 210Wh/m(330 miles real range) in dead of winter heating like that and if you are in stop and go just using the seat heater is mostly enough.
The heat pump is just for lazy people, who like to have it on Auto. The only real advantage is if you are camping inside the car in around 0-10C. And also, not confirmed, during battery heating
Don’t have to take my word for it. TONS upon TONS of threads on here and FB about shitty range in cold weather. Don’t say I didn’t warn you.

Yeah, and tons upon tons of other clueless threads about other stuff like degradation. If "tons upon tons" of something on the internet were any indication for anything we wouldn't have the dumbest person alive as a president of the US...
Do you even own a Tesla or have experience with one? Because I have two winters behind me in a Model 3 and actually know what I am talking about and have most of it on video, including summer range in winter cold in the city by following exactly the advice I gave above.
Looks like a lot of work to drive a "smart" car.
Don't listen to him. If heat pump doesn't help then why did Tesla decide to include it.
I don't think he's saying it doesn't help. He's just conveying some tips for improving winter range. I know I'll give them a shot this year.
Yeah having a “check list” to start your car to gain “some“ miles is completely pointless to me but whatever. Kinda like hypermilers driving 50mph on the freeway and saying yeah...you can totally get EPA range. Get real.

Exactly. This was as a suggestion to take the car if heat pump was the only variable. It does take a few extra steps to make the car more efficient without the heat pump, but it is doable. And no,
just turning on seat heater doesn't require masters in engineering like some make it to be...
I think Tesla could actually improve their PTC via software - the main problem was actually the software that turned the AC on to cool down the air(humidity?) and then heat it up. Also they fired up the heater faster(using more kW) so it means if you drive slower and heat much, the penalty will be higher, because the heater will heat the car regardless if it takes you 60 minutes to travel 10 miles or 10 minutes.
This is also what Elon said on Twitter, basically confirming anything I previously said.
The main and biggest advantages of a heat pump:
-slow traffic, short drives in temps of 0-10°C - biggest advantage if you like to put it on "Auto" and forget about it - can be mitigated by turning manual and using seat heaters on PTC car.
- camp mode in the same temp or slightly below freezing.
- (not confirmed) heating up the battery should be more efficient- will test it once it arrives
Negatives:
-weight
-another thing that will break(PTC elements are more robust)
-noise - these things are loud
- not much benefit in warm weather or long commutes over high speeds above 60mph-the benefit here is roughly 2kWh over the full battery charge. This is about 3% more range or 10 miles or so at highway speeds

Yeah, why don't we... To achieve EPA you actually have to drive at about 60-65mph, not 50, on a mildly cold autumn day. Can do around 70mph in the summer

I think we will (hopefully!) learn that the new M3 refresh has the Y motor with more capability - Nobody can confirm, but it would make sense to be able to continue to unlock more speed with updates
