It is one possible alternative to a repetition of the Model 3 introduction, that Tesla will likely not want to relive. Talk about underestimating demand.
So Model Y production to start somewhere between the super optimistic Q3 (e.g. 1/2 year after Q1 reveal) and the not-to-be-redone two years after reveal (since two years is what it took go get the Model 3 into what could be called real production, after the reveal on the eve of 2016Q1).
Maximizing commonality between the Model 3 and Y will be crucial, as I can't see how the latter's near-certain success won't come in some parts at the sedan's expense. Europe has seen a massive move towards SUV and crossover bodystyles too.
Thus far, I think we can expect the battery pack, motors, computing hardware and sensors, and parts of the interior to carry over.
The Y will be another seminal electric vehicle sending shockwaves through the industry. I have a hunch we may eventually see both a five and a longer seven seater.
I also recall him saying there were too many features (like the glass roof) all at once. So expect shorter turn around this time with that lesson learned. Plus it's based on the Model 3 frame to start with as I believe. He really wants the Truck, so Y needs to get out of the way already, but today is pretty aggressive timing, maybe we get a date for the reveal out a few months.
In my opinion, one of the very best things about Elon Musk's fascination with the pickup is that the team around the Y gets to chug along [heh] without too many undue stressors. This is Tesla's next crucial vehicle, and if there are any significant changes, they should ideally be found on the factory floor.
I can't see how the Y won't be beyond popular.
Globally established manufacturers should watch the Y very closely and have their thinking caps handy, while the sadly much reduced and more parochial American firms will be handed a really hot potato when the pickup arrives to suck up the high margin business first.
I think some Chinese company will be the high volume (low price) producer in the future. Just not sure they can break into western markets.
Make that many. There are hundreds of firms angling for their piece of the cake over there right now. In a competitive market [we'll see about that...], the winners will make their global weight felt soon enough.
It's instructive how experienced German engineers [and South Koreans for the battery tech] were attracted to China and helped foster a more [and less] competitive industry. The same impulse has led to investments in the US with a clear view of gaining knowledge.
Elon Musk recently tweeted that the relevant talent is scarce. It's such a pity the US is so intent on revolving around a very limited event horizon right now.
EDIT: I wish Elon would let Deepak Ahuja finish his sentences. I always listen very attentively to what he says.
