Q4 Model 3 production and deliveries estimate
So
@Troy asked for people to make their Q4 Model 3 production estimates, and here's my entry for the 2018 Q4 Model 3 production estimates
lottery pool:
So my official estimate for
Q4 Model 3 production is 62,800 - with deliveries about 4,000 higher than that:
66,800.
Methodology:
My method is exceedingly simple, it relies on a visible cyclical feature of Tesla Model 3 VIN registrations with the NHTSA, which can be seen on the Model 3 VIN tracker website:
This "feature" is an apparent 'quiet period' or 'pause' in new VIN registrations at around the end of quarters - preceded by small adjustments to the maximum VINs. This defines a maximum allocated VIN for that quarter, which can be extracted historically for all 4 quarters of 2018:
Code:
Model 3 VIN allocation ratios:
Quarter Maximum VIN VIN increase Production VIN-to-Production-Ratio
==================================================================================
2018/Q1 20,581 +15,787 9,766 61.86%
2018/Q2 53,800 +33,219 28,578 86.02%
2018/Q3 116,270 +62,470 53,239 85.22%
==================================================================================
2018/Q4 ~189,964 +73,694 62,804 (est.) 85.22% (est.)
Note how the 'VIN allocation ratio' has stabilized to around 85-86% in Q2 and Q3, and that we already know the Q4 maximum VIN today - what we don't know is Q4 production.
If we make the (big) assumption that in Q4 Tesla has set their production targets in a similar fashion as they did in Q3, and allocated VINs accordingly, then the production target can be calculated by applying the Q3 ratio of 85.22% to the Q4 increase in VINs allocated (+62,804) - which gives a 62,804 production target for Q4.
Also note that these VIN numbers are not sampled and don't suffer from selection bias - they are the pure maximum VIN numbers registered with the NHTSA at the (near) end of the quarter. Hence the 'only' flaw of my estimate might be that VIN allocations might not be uniform across quarters - like they weren't in Q1.
Caveats:
- Both the Bloomberg tracker and @Troy's tracker is projecting much lower Q4 production rates: the @Troy tracker's estimate is now down to 51.6k Model 3's made in Q4.
- Tesla is free to change their VIN allocation patterns at any time. They could make much fewer (or more) Model 3's than my projection.
Anyway, Tesla keeping this ratio more or less constant would be a funny and predictable way to communicate their production target without actually communicating it officially.
(Not advice. In 5 days I might be looking back at this post in embarrassment, wishing for a 'delete' button.)
