    I checked my Delivery Estimator and the language has changed.

    Standard Battery
    3/21/18 - 220 mile range with RWD

    Dual Motor AWD
    3/21/18 - No comment on range options... "Instantly controls traction and torque, in all weather conditions"
    2/07/18 - Choice of 220 or 310 miles

    I just checked and it's the same for me.

    Looks like stars are aligning for Tesla to push all SR production into 2019.

    Aren't the S and X are more efficient with dual motor? My understanding may be wrong, but I think the two motors are geared differently and the less efficient motor for a given speed could "coast" while the other kept the car moving.

    Perhaps dual permanent magnet motors aren't more efficient, due to not being able to "coast" one of them, resulting in the SR range dropping below 200 miles?

    I'm seeing the same thing today as well. :(

    maybe not.
    I have Mar-May for current production, but both SR and AWD show Late 2018 for me

    I always sort of figured that was an oversight on their part. Either way, it's looking like 2019 for me.

    I think that is extremely unlikely.

    In the S and X the front and rear motors work in tandem for acceleration with the bias being on the rear motor. For cruising it is 100% the front motor unless there is a traction situation, as far as I know. The dual motor versions do see range improvements but they are pretty modest. Keep in mind that you are carting around another 40+ kgs in the dual motor configuration compared to RWD.

    *sugar*, really hope not. It will be worse than the Alcanteragate scandal! SR with AWD

    My delivery schedule still shows Late 2018 for SR, Late 2018 for AWD (with SR and LR removed from description now)

    Will that mean no SR AWD?

    We'll have to see how it develops, but I'm thinking this was Tesla not wanting people to think they can buy an AWD SR car in Late 2018 when they introduce the AWD LR cars, not Tesla saying the SR will always be RWD only. The older version of the text seemed to being saying the AWD launch would offer both battery sizes from the beginning.

    IIRC SR was going to be offered before AWD so the original text was correct. They failed to update it after pushing SR back. Now they have...

    This is referred to as torque sleeping. The S/X do this for more efficiency since the front motor is smaller and more efficient.

    So the question is can the 3 can torque sleep a motor? If not, wouldn't it seem likely that you'd lose range due to the extra weight plus the need to continually supply power to both motors?

    The range difference is far from "modest" in the non "P" version of the Model S in real world testing. When my Model S was still a 60D, it had virtually the same highway range as an 85 RWD. Now that it's a 75D, I can easily achieve 275 miles highway while maintaining speed with traffic.

    Likely more to do with how the old wording could be misconstrued as SR AWD becoming available at the same time as LR AWD rather than more in line with the [more logical] timing of roughly when SR becomes available on rear wheel vehicles.

    You can coast/sleep a PM/PMSR motor. Although, based on motor design/ inverter efficiency, it might be better to feed half the power to each.

    I see that Canadian deliveries are now ahead of first day US SR "line waiters"; so much for Elon's "do the right thing."

    If Canadian deliveries push the 200,000th US car to the beginning of the next quarter, that is good for US purchasers as there will be an additional quarter of EV tax credit.

    The Canadian deliveries cited above are for mid-2018; do you think it is likely that the 200,000th US delivery will be after the third quarter 2018?
