Not at all. Perhaps you did not see the original post which pointed out that 1,000 KWh of batteries can power 1 semi or 13 M3s at 75 KWh. This is simple math. Divide 1000 by 75. Tesla seems to strive for 25 or 30% Gross Margin on its vehicles. Say they are confident they will reach that on the M3 once production ramps to planned level. If the Semi reaches the GM Tesla aims for, ideally its GM would be same percentage as M3. Say that was 30% GM. $180,000 x .30 = $54,000 gross profit. The current LR M3 runs about $50K.
$50,000 x .30 = $15,000 gross profit. If you only had 1,000 Kwh of batteries available and had to choose between using them to make 1 semi or 13 LR M3, which would be the more profitable option just from the vehicle sales standpoint?
13 x $15K = $195,000.
Fair enough, I did miss your initial reasoning. But gross margin is simply the profit margin from building the vehicle. The operating margin for the semi should be higher shouldn't it? Sales and service (warranty support) for 13 model 3's would be significantly more than the sales and service of a single semi. Perhaps enough to overcome the gross profit difference?
It's reasonable that warranty service costs for 13 M3 would be higher than for 1 Semi. But what does annual warranty service for M3
run? 1K? 2K? Multiply by 13. It would be quite a few years for this to make up for a $141K profit differential.
Anyway, leveraging off my original point, this thought exercise is flawed, as it's scoped under the assumption that Tesla is battery-production-limited. The situation is that in 2019, once the gigafactatory is nearing completion, Tesla will be vehicle-production-limited.
Still not reading what I wrote. The observation is that Tesla can make more immediate profit using cells for M3/MY than Semi.
This only becomes of potential impact to Semi volume IF increasing battery production can't keep up with demand and production capacity to build M3 and MYs. We can hope that Tesla will not be able to build enough M3 in 2019 and 2020 to outstrip GF1 battery production, but this isn't as certain as you suggest. Tesla aspires to build around 500K M3 in 2019. That equals 35 GWh. GF1's original planned capacity.. But some amount of that must go to increasing storage battery needs. They plan to begin producing MY in some factory beginning (perhaps) late 2019. 2020 sees higher M3 production and ramping MY. 105 GWh from GF1 by 2020 or later is still aspirational at this time. We don't know how many GWh GF1 is producing now, nor do we know for sure when it will reach 35GWh and then 105.
I hope like everyone invested, that the aspirations are met about when they have projected. But their aspirational goals often take longer than originally projected. It remains to be seen whether they will be limited over the next five years by how many cells they can produce or by how many vehicles of different types they have capacity to build. If M3 production in 2017 was 100 - 200K as Elon guesstimated two or three years ago, GF1 would not have been making enough cells this year to support that many.
