    Seems like performance AWD Model 3 pulls more than 1G accelerating. What’s his comment about special modes mean?

    Perhaps it means there's an acceleration unlock mode similar to Insane/Ludicrous :D

    Needs to be track modes for reduced or negated traction/stability control.

    Sounds like it might actually be a proper track toy, which I seem to recall everyone saying it wouldn't be. (That like the S it would be a one trick "drag race" pony.)

    Let's hope "15% better than an BMW M3" meant more than 0-60 times.

    It probably didn't.

    Seems most likely that it just pulls more than 1 G transiently because otherwise it would do 0-60 in ~2.73 seconds if it maintained 1G throughout the run.

    Even at 2.73 sec, that's still not stepping on the toes of the P100D. Though maybe it's just wishful thinking :)

    If it starts at 1G and holds constant torque (like all the previous models) until 358kW I get 2.96 or 2.27 with a rollout...

    Incidentally, if Tesla can do 680 Nm with just the rear motor and optimizes for gearing and power on the front induction, if they can keep both motors producing 358kW all the way to top speed they will have a problem with their positioning relative to the P100D, not in the 0-60 but in the quarter and half mile times.

    0-60 and rollout times look good. Trap speeds for Teslas are much lower than ICE. 11.1 QTR mile trap should be about 119-121mph

    Am I correct in my understanding that your calculation is assuming an initial surge of 1 g acceleration but just keeping torque (not acceleration) constant for the run? If so it's interesting because the calculated number exceeds the linear 1 g acceleration calculation which implies that it exceeds 1 g for some period of time during the 0-60 run. The number I had was calculated just using basic physics equations of what happens with a constant 9.8 m/s2 acceleration linearly.

    I will definitely be more than happy if my P3D (or whatever we agreed to call them) produces those performance numbers you calculated. I won't care what hardware is different or not and what is software difference or not from the AWD if they can fully backup that performance with warranty service. I would think that I will definitely need to get better tires to give the car enough traction to meet up to it's potential.

    Yeah- someone really needs to figure out how wide you can go with wheels/tires and not have rubbing/clearance issues.

    Tsportline confirmed the 18s will take 255s without getting in the way of anything on the stock 18x8.5s... that's 1.1% diameter change from stock though, and as wide as you can go on 8.5" rims.

    Ideal would be 265/40 (rather than stock 235/45) since that's exact diameter, but you'd need 9" wide wheels for that and unsure if it clears.... (and I mean, technically, you CAN put 265s on 8.5" wheels... but it's out of spec for the tire)

    So Elon confirmed that if you have the right tire and wheel setup you can get the 0-60 down to 3.3.

    He also confirmed that the 20" PS4S's are a range focused tire (hence the 500 treadwear rating cited by TireRack and narrower 235 tread)

    Given this new piece of info, doesn't mean there's potential significant differences between the P3D base and P3D+ in terms of 0-60 times?

    he did not confirm that.

    He say that might be possible.

    (the or better is interesting... and also makes me wonder what the 4.5 spec on the AWD model turns into with excellent tires...)

    Actually that makes it less likely there's a huge difference.

    Before we thought the difference was 18s with mediocre all seasons vs 20s with the absolute best street summer performance tire.

    Now it's apparently 18s with mediocre all seasons vs 20s with less-than-stellar street summer performance tires.

    So maybe the extra weight on the 20s for no more width is offsetting the smaller-than-expected tread traction difference?


    it does reinforce that for folks planning to stoplight race instead of track race they're almost certainly better off skipping the Performance Upgrade and just putting regular PS 4s tires on the Aeros.

    P3D ≠ P90D.

    M3 P will be super fun to drive. My tire budget will need to double. My wallet will not like it:(
