Yup, I never go back-and-forth with guys that are in the "the LR AWD with Performance Boost is equivalent to the Stealth performance" camp. They're entitled to their opinion. My opinion is different than theirs, and neither of us will convince the other to change sides. But I just gotta add my two cents here.... I agree with ya, MJP. Guys can go ahead and tell themselves that all they want, but the acceleration time difference is there, the track mode is there, and the retained resale value is there. IMO, those aren't "pretty much" the same.
But again, they're welcome to their own opinion.
For the same two thousand dollars that guys are now paying for the performance boost option on LR AWD, we got our Stealth performance with better acceleration and track mode. It's really a shame that Tesla took so much value out of it. Personally, I would've loved to see Tesla offer the full on Stealth upgrade option to LR AWD owners, but since there is a motor difference between newer LR AWD and Performance Model 3's, that just wasn't an option. A real shame, too. That would've been a lot of goodwill that Tesla could have created. Sure, it would've made our cars less of a "unicorn," but I'd rather have the goodwill than a unicorn, TBH.
As far as being "pre-thrashed." The verdict has yet to be given, but my little hunch is that we'll see much less wear on electric vehicle drivetrains that have been driven hard vs. ICE. Electric motors don't have the same type of wear and tear profile that ICE engines do.
I have much less concern about the drivetrain than I do the battery, really.
