I was quite surprised about the level of the consternation expressed by many about perceived weak MS/MX guidance, as it seems that some important details were overlooked. I did not have much time to post over last few days, so here is my belated take on the guidance.
I am probably getting a lot of people bored preaching about how many cars Tesla have to have in transit pipeline under steady state operation. This concept is very important to consider, particularly as they are closing in on the mass production of M3. So far, with the few exceptions, Tesla deliveries were hugely lopsided, with 50 to 70% of deliveries made during the final month of a given quarter. Needless to say that this is less than ideal situation as it puts unnecessary strain on logistics and stores. It is quite obvious, that with the deliveries of M3 blending into the mix in second half of the year, and Tesla probably scrambling with opening additional stores and scaling up deliveries in the existing stores, this situation grows from less than ideal to simply unsustainable. So Tesla must even out monthly deliveries by the second half of the year, which means that they need fully filled transit pipeline.
Assuming steady state production of about 2500 cars/week and average global time in transit of 6 weeks means that fully filled transit pipeline requires 2500 x 6 = 15000 cars. Let's be conservative and ignore additional cars that will be required to fill newly opening stores and service centers.
According to the Tesla Q4 deliveries
press release at the end of Q4 Tesla had 6450 vehicles in transit to customers. This means that in order to fully fill transit pipeline Tesla will need to add 15000 - 6450 = 8550 cars to it.
So if we assume that Tesla is going to gradually fill the transit pipeline over next two quarters, in order to deliver 47-50K cars they will need to produce 55.5 - 58.5K MX/MS. In order to be sustainable, this production rate will have to be matched by the rate of incoming orders.
So unpacking the MS/MX delivery guidance:
- The current yearly rate of the incoming orders for MX/MS is about 112-118K
- The projected production rate is about 55.5k-58.5K per 6 month or 2312-2438 cars/week (48 production weeks per year). I would be shocked if Tesla did not sand bag this, at least by very modest amount.
- Assuming that current rate of incoming orders will be maintained going forward, there will likely be 55.5-58.5k MS/MX cars delivered in the second half of the year
- Tesla is or very close to the nominal two shift production capacity of 2500 MS/MX per week
One interesting detail that came out of the leaked Elon e-mail to the employees is that Tesla hired workers for the third shift. This potentially could mean that Tesla can increase production throughput to higher than 2500 MS/MX per week, if final assembly production area will indeed switch to 3 shift operation. BTW, for anybody with upcoming factory tour in the near future this is one piece of information that would be very useful (whether final assembly area is currently running three shifts).
