That response does not address the question of the missing horsepower. I posted the following in the other thread where this is being discussed:
Tesla can't have it both ways.
They can't explain now, almost a year after the P85D was first announced, that they didn't really mean 691 HP in the way everyone else thinks of 691 HP.
Watch the following video, from about 2:04:
That's Elon Musk quite recently answering in the affirmative when asked about the P85D, "691 HP?"
There were no inane qualifiers about motor power, etc., etc. The interviewer restated the commonly known fact, propagated by Tesla, that the P85D makes 691HP, and Musk, on camera, confirmed it.
I'd ask anyone who feels like commenting on how we're whining, and how Tesla didn't mislead to please watch those ten seconds of that video before making your comments, because I think if you watch that video, you'll be hard-pressed to make your comments with a clear conscience.
Edit: It has been pointed out to me via PM that the interview with Musk was clearly edited. I hadn't noticed that, but looking at it again I'd agree. While we don't know what Musk might have said after answering in the affirmative, it may have included disclaimers or qualifiers. I would expect, though, that if they were significant, a reputable organization like "60 Minutes" would not have just edited them out.
