I doubt any of us wonder if TSLA will rise over it's ATH, it's just a question of when we pass $1,200 again.
I think TSLA will pass it's ATH on.....February 3rd, 2023.

To clarify, those heavier batteries were the Plaid and Rivian. Rivian alone is nearly 800kg. Our 2020 Model Y was 440kg.
Personally, I don't think that the seats, center console, and carpet are 100kg, so the battery pack itself is probably heavier than the old design. The big savings is in eliminating the load floor, both in terms of weight, raw material cost, and labor cost. Just being able to stand inside the vehicle and install the pillar trim rather than hang into the vehicle from outside, bend backward, and clip it in is a huge ergonomic advantage.
Tesla is playing the big picture game, seeking gains across the entire vehicle, rather than looking at single part savings.
Q: Does this pack have liquid cooling? Where were the coolant connections?
A: Can confirm, I drained the coolant, got about a gallon in the pan, and about four ounces on myself.
One connector in front, one in back. Other coolant lines are routed along the sides of the pack, such as the RDU lines, and the coolant return line for the battery.
Well I can tell you that the one [battery pack] in the Model Y we tore apart back in 2020 was 437kg. Everything was weighed on calibrated scales before we finalized the report, so I can say fairly confidently that it's correct plus or minus a couple of kg overall.
Seat weight quote in the comparison report is for both. Front Driver Seat 22.2kg, Front Passenger Seat, 22.6kg. Again, this is per our mapping software from which that report was generated.
For SAG I went and pulled the new center console off and weighed it. It's around 10kgs. So, now we're up to about 55kg. Add maybe another 10 for the carpet and foam, and you get 65kg. Meaning that the battery is about 35kg heavier than the old version. Let's just hope I don't get in trouble for saying these numbers publicly before we officially publish them, yeah?
…
I think the big save is being able to get rid of the load floor in the body in white. It might not be a weight save at all in the end, but it's definitely a cost save at piece cost level, and a systemic level by eliminating part numbers, warranty claims and scrap due to those part numbers, etc.
One of my larger concerns as a mechanical engineering with a background in industrial engineering, and just being an ethical person, is always ergonomics. Being able to get inside the body and STAND UP to install the interior trim with a pushing motion, rather than crawl around in the body over pokey studs and brackets, or lean in door openings to install stuff with a pulling motion, makes a huge difference in workplace safety and stress injuries.
[The drop-in structural battery pack] also simplifies the installation of lots of other interior trim. Typically the pillar trim has to be installed from the outside by people hanging through the door opening, with this design the operator can stand inside the body and snap them in and secure them. Greatly increases safety and ergonomics, and thus time on the line.
Energy output is over 100 times the input needed to manufacture solar panels
According to a third-party study, the projected output over the 40-year warranty period of Maxeon solar panels exceeds the energy demand of manufacturing them by over 100-fold. Plus, more details from the Maxeon 2021 sustainability report.pv-magazine-usa.com
The test found that Maxeon 3 solar panels had an energy payback period ranging from 0.13 to 0.45 years for ground mounted module, and 0.27 to 0.92 years for a residential rooftop system. For ground mounted panels, the energy payback period can be as little as 47.5 days.
I still have high hopes for TSLA to install panels in my state one day. Maybe after I get my Texas made Tesla I can eventually get some Tesla Solar on my roof.
ESG ratings and UAW accusations are missing the point. Tesla is making major advances in safety for line workers by badass engineering design.
True, but I did once get one of similar vintage while driving across a UAE desert. The battery was charging well. Luckily the same trip now would be in a Tesla.You haven’t driven my 1980 BJ40 Land Cruiser lately.
CNBC trying it's best to say otherwise, so there are definitely hedgies spending money to spin this as a negative.
To me, -1% TSLA with QQQ down .85% is quite strong and smells like we end the day green. We shall see!

This often overlooked difference in business models (among others) is a key first principles win for Tesla. Not relying on low quality components that are designed with limited life expectancy to maximize dealer and OEM profitability. The ability for Tesla to say that the best service / maintenance is NO service / maintenance and honestly mean it. It promotes brand reliability. This is the right side to be on.

I'm pretty sure with the total world motor vehicle fleet that needs to be replaced at 1.4 billion vehicles we won't be worrying about unbreakable cars ending the world auto market for a very very long time.Sooo... bring on Teslabot and energy and insurance and and ...? Because infinite demand for products that don't deteriorate does not go on forever. I guess Tesla could follow the smartphone manufacturers and keep convincing us to upgrade phones that work fine, but this doesn't seem like a wise business model, eh? I mean, once Tesla reaches 20 M cars per year / it'll take them less than a decade to replace virtually ALL the cars on the road, right?
Okay, this will be a "good" problem to have, many years in the future. No alarm bells yet, but something to think about based on first principles thinking and the ceiling of compound growth rates based on limited demand.
Insightful Reddit comments from an account that’s apparently Stuart from Munro & Associates.
I want to emphasize the comments on ergonomics. Improving employee safety is the Number One Thing a company’s engineers can do to improve morale, quality, cost and throughput.
Tesla’s rear gigacasting on the Y enabled them to design the Supertub depicted on page 42 of the 2019 Impact Report (link). I think people who haven’t worked in manufacturing missed the significance of that reveal. Tesla is a mission-driven company and as such they always tend to sneak the best info into the Impact Report.

The Supertub is one of the main reasons why the Y has less labor cost than the 3. Look at the positioning of that technician in the image. Standing up straight, running the tool at shoulder level, direct line of eyesight on the nut being torqued. Damn near perfection from an ergonomic standpoint. Nobody else in the car industry has this as far as I’m aware, because it requires an IDRA Gigapress.
With the structural pack, now the whole freaking Model Y interior can be assembled in a comfortable body position and with more employees working simultaneously at a production cell because of the greater ease of access. This matters. Fewer people going home hurt after work, and fatter profit margins. Win win.

There is also a lot of unmet demand, people that have never owned a car, or never had transport and energy.I'm pretty sure with the total world motor vehicle fleet that needs to be replaced at 1.4 billion vehicles we won't be worrying about unbreakable cars ending the world auto market for a very very long time.
IDK. If each replacement had 10x utilization, would be more like 150M needed, so next decade is all.I'm pretty sure with the total world motor vehicle fleet that needs to be replaced at 1.4 billion vehicles we won't be worrying about unbreakable cars ending the world auto market for a very very long time.
Tesla has admitted the goal of 1M miles for batteries and motors. That's arguably 5x more than conventional ICE. Not all components will last this long. But don't you see the significance of having this conversation vs traditional manufacturers wondering at how many miles the motor brushes ought to be replaced at to keep their dealer network satisfied...Sooo... bring on Teslabot and energy and insurance and and ...?

What Stuart is saying in the weight comments is that it’s not a direct comparison to the battery of the Y they tore down in 2020.if he’s correct, a lower energy content 4680 pack weighing 35 kg more than a long range 2170 pack is quite disheartening.
So I guess some of the weight savings from removing the underbody is currently used up by lower density cells?
That seems to answer the puzzle why the vehicle is not much lighter than a LR 2170.
Hopefully Tesla pushes in more advanced chemistries relatively quickly! They claimed a 56% range increase (by 2025 IIRC) which only makes sense as a referral to pack energy density.
