Exactly. German car manufacturers are announcing to start shipping products from next year. They are not announcing at what price and volume they expect to be selling those. But you can safely assume this will be very high and very low for quite some time. Everybody seems to be going on about Teslas well documented struggle to reach 5K cars/week in production. My guess is that it will be quite a bit of time before the traditional manufacturers will be able to boast similar numbers.
All indications are that German car manufacturers are taking the same path as Tesla has over the last ten years: start shipping in low volume at the very high end of the market and (re) learn how to build products in this market. My guess is that they are themselves expecting it to take quite a while to catch up; probably in the order of five to ten years. The currently announced and rumored models are stop gap solutions to not fall behind any further. They are behind in specs and pricing and they can't ship them in large enough volumes. But it is better than having nothing in the market.
It's what is going to come after those that is going to make or break them. Look for the second or third generation models of these vehicles by 2023-2025. By then they should have sorted out logistics and battery production issues and figured out how to make better EVs for less money.
Meanwhile, Model 3 sales alone are outpacing their high end conventional models in the same price class in the US. Considering that that is where car manufacturers make their money, that has got to be hurting financially. Likewise, Model S is selling pretty substantially in Europe, and out selling several of the BMW an Mercedes models in the same price class. In Germany! Model 3 has yet to start shipping here in serious volume.
With Tesla steadily increasing production, improving efficiency in their production, opening new factories (and planning to build more), rolling out to more countries, and dropping prices over the next five years, that is going to be a problem for other manufacturers for a while.
