    In just 2.5 years, we've gone from 11.7 second P85D to 10.4 P100DL. The frunk weighs no more than 30 lbs so I'm not really sure it made all that much difference.

    I think that GoPro is adding a bit of drag preventing 125 mph trap speed.

    That's crazy, just removing the frunk trim. Isn't it just some plastic, foam, and carpet? What's next passenger seat, trunk trim and rear seats?

    Yeah if he ditched the GoPro and floor mats and skipped a meal or two he might hit 10.39 :)

    Awesome.

    It's clear that weight reduction and in the right place, made a big difference here.

    Different tracks, but this is nearly 2 tenths quicker than the prior record set just a couple of days ago, and a significant improvement over that same car's prior best before the weight reduction.

    I believe that in his video he says that they've run multiple 10.7s. To go from 10.7 to 10.4 after doing nothing more than removing 30lbs off the front end of the car, there's no denying that made a difference.

    I assume with AP2.0 and the self driving update next year it will even have a greater weight reduction, but who gets the credit for the run? The software development team :)

    I'm quire certain he has removed a lot more than the frunk liner. 30lbs isn't going to amount to a hill of beans on a 15 second car, to say nothing about a 10 second run.

    Right. No way 30 lbs makes any difference at all on a 5000 pound car. Were the rear seats shown in the video? Maybe he removed those.

    Seats are an easy removal. I suspect the front and rears were removed, tire pressure lowered to ~25lbs, possibly some sort of cooling to the stator.

    Maybe he staged at the rear tires, LOL.

    Maybe he never lowered the PSI until now.

    Did they use LM to get the best time? Is there any way to get info on how to repeat this performance for other P100D owners?

    Launch mode, yes. Probably lower tire pressure - perhaps 25psi. Beyond that, I think it's just weight reduction.

    I've read all of the comments following the YouTube video.

    He makes no mention of, nor does he alludes to, any other weight reduction aside from the frunk removal for the purposes of this 10.44 pass.

    He does however state that further weight reduction efforts aside from the current frunk removal may be utilized in future runs.

    Since the only claim he has made regarding weight reduction is the frunk removal, and his videos over these last several months appear to be on the up and up, I am inclined to believe that his improvement to this point , i.e. achieving 10.44 over his prior bests in this low options version of the car, is related to his frunk removal and no other weight reduction efforts thus far.

    I agree but I suspect that this was a different track with better preparation. One track that I go to rarely (too far away) is 0.1 sec faster than my usual one.
