Mmm, don't think so. On the Q3 ER call, Elon estimated Model 3 production of 7-10k/week in Fremont plus 5-8k/week in China. He also said they planned to start doing partial Model 3 production in China by the end of 2019. It may Tilburg-ish initially (I'm not sure) but the point is to add capacity (5-8K/week) as well as address tariff issues. Elon's estimate on the call for total Model 3 production was 500K-1M/year -- I used 700K/year as an estimate which will likely prove to be too low.
Elon also said on the call that Tesla had already approved a Model Y prototype for production and confirmed again that they plan to have Model Y in volume production in 2020. CUVs are more popular than sedans so Elon's rough estimate of 1M Model Ys/year sounds right to me.
It is unclear whether Model Y will be produced at a new U.S. factory or the Gigafactory, but Elon has already made clear it won't be at Fremont since it's too crowded. Tesla also has said Model Y will be produced at its factory in China, but there no reason to believe that will hamper the 5-8K/week Model 3 production in China that Elon estimated.
So Model Y should be in volume production in 2020, while Model 3 production is ramping up in China. Semi production may begin at about the same time as Model Y, we'll see. Add in storage and solar roof ramps and 2020-21 should bring more explosive growth.
If Y is to have volume production in 2020, it is easily determined it must be in a factory already constructed. I believe there is zero chance for 1mil Ys to be produced at Fremont, so either Sparks or some existing factory that Tesla will be acquiring. Can’t be a new factory yet to be built.
