So when I surmised a few days ago as to what Tesla's production roadmap would look like for the rest of Q2, I pointed out that it would likely be most worthwhile to produce exclusively for North America to maximize Q2 profit and minimize logistical and other issues that could come up during the quarter.
One critical part that I didn't think about, however, is that if Tesla delivers no cars to Europe, they get no FCA money. So it does make a lot of sense that they will produce European spec cars for a few weeks so they can get some sort of FCA credit payment, then shift to North American cars. I would think that Model Y would start right off the bat doing North American production though. It's not clear to me why that wouldn't start right away, unless there's either a supplier shortage, or they can't produce Euro-spec 3s and NA-spec Ys at the same time for some reason.
I'm also not sure it's confirmed that Y is not being produced right now--wonder if any trucks are picking Ys up off the Fremont lot?
