Still off-topic, apologies all.The Model S definitely, especially w/the E-Mission coming Any Day Now(tm)** The Model S is getting close to the 7 year mark, right? ((EDIT: Oh, the official 7 year anniversary was yesterday.)) I know the parallels may not hold that well but typical automobile industry practice would mean it's due for a major update, well past the facelift update it got with the nose.
The Model X is still pretty young to be doing a rework on it and it's got more differentiation going on.
** Perhaps latter 2019, maybe slipping to early 2020. I don't think there's even limited 3rd party reviewer access yet. Just an internal, though mostly credible, driver talking up first experience with the prototype.
Of course Tesla is more active with rolling changes to models. A 2018 Model S is functionally and and in terms of interior a departure of sort from the 2012 early production ones.
I'm still confused about Porsches upcoming offering. Is it the almost-Panamera or the almost-Cayenne? To sell any S/X cars in Germany, charging speed will need to be adressed. Less than doubling will not suffice. To remain competitive on price and spec, a larger 2170 pack will be needed. If if the same physical size. And production cost will need to be brought down. Make an S as if it were a 3. Same number of parts, same production effort more or less.
