johnnyduval, I can't disagree with most of what you've written, but I do want to comment on a few things.
1.) I was surprised at the favourable Signature exchange rate here in Canada. I'm not so sure that the regular production models will have such a favourable exchange rate, but I expect it to still be better than the going rate. Tesla may do the same in Europe.
2.) Audi's 310 mile range is based on the less stringent European (NEDC) standard. The Model-S also has a 310 mile NEDC range. I suspect that this number will get modified when it actually hits production.
3.) Audi (and the other manufacturers) have been promising EV for decades and they should have already be selling them now. The only reason why they're making these announcements now is due to Tesla (and to try to get consumers to hold off purchasing a Tesla). I wouldn't hold my breath that Audi will be releasing this SUV on time in 2018. And if they do release it sometime in 2018, I bet it will be very limited numbers and in limited markets.
4.) The Audi EV is a 4-seater, not a 5/6/7 seater like the Model-X
5.) This will be Audi's first EV vehicle. Are you going to trust that Audi has created a perfect, flawless vehicle on their first attempt? I suspect that their roll-out will make Tesla's ramp seem perfect.
6.) Finally, there is no guarantee that the concept in your link is going to look like the actual production model. They usually look worse and lack many of the fancy features shown in the concept.
