For the blog I quoted from
http://www.teslamotors.com/blog/factory-upgrade, it has nothing to say about the bottleneck you mentioned. So it's either you misread the information or TM misled the readers by hiding sth. I believe >99% of the people will think the TM production rate is @ 1k/week level instead what you claimed bottlenecked @ 800/week level after read the blog. Btw, I've pointed out this to you several times, you just can't provide solid proof and I assume it's based on your speculation!
Even in Q4 shareholder letter, the BIW upgrade has nothing to do with model S production rate, it only talks about model X. So it still can't explain why the "minor adjustments" can't be done in Q1/Q2 to significantly improve the productivity for model S as stated in blog.
Edit: Why running current BIW line at more than two shifts, using overtime, not the most efficient way of using resources? If BIW is indeed the bottleneck, keeping this bottleneck and make rest of the assembly line idle for a large percentage of time is the most inefficient way of using resource and capital. Should demand is not an issue and solely production constrained, TM should had all the motivations to attack any bottlenecks. Dealing with production line in house is way much easier than stimulating demand.
It is interesting that your choice of words to talk about production is always so ominous. This is not the first time we are having discussion on this topic, and words like "bottleneck" and "hiding" are always at the core of your argument. It seems to me that you are missing the big picture regarding the upgrade of factory production.
Just as a recap of the big picture, the Company miscalculated demand for MS/MX and equipped the factory for a roughly 40K of combined yearly production of MS/MX. One has to be aware that production of automobiles, especially at the factory that is as vertically integrated as Tesla Fremont factory, is a very complicated process, with a general assembly line is just at the tip of the multiple independent manufacturing processes feeding into the final general assembly. These include stamping of body parts, body in white (BIW) assembly line, motor and drivetrain assembly, battery assembly, internal aluminum parts casting and machining, plastic parts casting, paint shop - just to list a few. So after couple of quarters of production, seeing demand much stronger than originally expected, the Company realized that in order to meet this demand they need to upgrade all of the production processes and production areas to reach the originally not anticipated demand which, as far as we know is now expected to exceed 100K per year. Since the company needed to achieve all these upgrades with minimal interruption to the continuous production, they came up with the plan to upgrade these multiple production areas in steps, starting with the top of the chain - general assembly line. We are now still going through this multistage process that is expected to be completed by the end of this year, with the company guidance production reaching 100K run rate. So your use of words like "bottleneck" and "hiding" indicates that perhaps you are not cognizant of this bigger picture.
During our several discussions on this topic you always mention that I did not "prove" these things to you, and all of this is therefore my speculation. I think that the problem here is that you either did not make time to listen through the several quarters worth of the earning calls, or did not pay attention to the portions of them that addressed the production issues. This is evident to me because all of the production issues described above I know from listening and then reading through the transcripts of the earnings calls. I strongly recommend going through the past ER calls if you want to understand the issues related to steps involved in the the factory upgrade.
So the blog referred in your post addressed things that **WERE** upgraded during the last summer stoppage, but it was not addressing things that **WERE NOT** upgraded last summer. In another words the blog post did not mentioned any upgrades to the factory that were planned, but not accomplished yet simply because that was not the subject of it.
One, however, can't claim that the company is "hiding bottlenecks" based on the fact that other future upgrades required to reach the planned 2,000 cars/week running rate by the end of 2015 are not included in the post - simply because these additional steps were discussed by the company multiple times **BEFORE** this blog post was published. It is completely frivolous to maintain that company is hiding something because you are simply unaware of it.
I do not have time to go through the multiple ERs to educate you on all of the steps involved in factory upgrade; as I mentioned before I strongly recommend you do it before continuing sharing conspiracy theories with the Forum. I am, however, going to address one specific issue which seem to always come up during our discussions - the need for BIW upgrade which was originally planned for Q1 of 2015, but I suspect is probably slipping into Q2 due to multiple reasons - we should hear more on this during the upcoming Q1 ER call.
Here is the exchange between Ben Kallo of Baird and Elon during the
Q2 2014 ER. Note that similar to the general assembly line, the body assembly line is
common to both Model S and Model X, but unlike with the general assembly line, TM is not going to add new line instead of the old one, but will add it in parallel with existing (800cars/wek) body assembly line, and then operate two of them in parallel for a while, before switching MS to the new body assembly line (2500 cars/week), and blending it with the MX which will be produced on the new body line right from the start. This will allow for a much more streamlined switch-over than what we observed with the upgrade of the general assembly line during last summer.
Ben Kallo - Robert W. BairdHey. Thanks for taking my question. As we look ahead to next year, in the 100,000 unit by the end of next year, is the biggest production increase happening right now over these two weeks, or is there some other step that has to take place next year to get you to that level?
Elon Musk - Chairman and CEOWell, there is a big step that's expected to occur in Q1 next year which is the bring up of the body line, the SX body line. So we've -- what we did the past two weeks is the assembly line where basically the bits get put together. But then the body line is where the body itself is welded together, welded and bonded together. So it's like the core skeleton of the car is created. And so we anticipate probably -- well, I'm not sure if -- it may only that we -- actually -- sorry, I take it back.
We're going to bring the body line up in parallel with the current line. So unlike this case with the assembly, we had to -- we didn't have too complete assembly lines, where we had to stop and retool. In the case of new SX body line, which is a line that is designed to be capable of 2,500 units a week, maybe more than that, conservatively at 2,500 units a week, at a lower cost point, we should be able to do that in parallel.
