    In the Model S, the larger battery configurations have faster 0-60MPH times. Is there any reason to believe this won't also be the case with the Model 3? Low 5s or high 4s 0-60MPH with a 75KWH battery would be great.

    Just wait and see. I tend to agree with you that the larger pack may have a faster 0-60.

    The larger batteries are able to provide more power so they will be faster, then the D will be faster yet with dual motors, and finally the P version with ludicrous mode, will be the fastest.

    The only reason the 0-60 was the same in the latest MS 60 was it was a locked 75. Canuck is correct.

    I would like to have the 75 non-D as an option to consider. 75kwh could get close to 300 EPA range, and 250 mi real world range, which would allow me to easily go anywhere in the extended Bay Area between Santa Rosa and Big Sur, and even to Sacramento and back, or one way to Lake Tahoe, on one charge.

    Right, when you are thinking about battery range, you have to know the worst case scenario.

    That ~240 small battery, might be closer to 200 in the worst conditions.

    Im hoping the 75 non D will have 300 mi range and 4.9 0-60.... Im probably asking for a bit much but what the hell...

    So are you saying that in the Model S the different 0-60MPH times are basically a matter of physics rather than a conscious decision on the part of Tesla?

    In many configurations, the maximum power that the car can produce is limited by what the battery can safely output. In some cases, the smaller battery pack limits how much motor power they are willing to offer.
    I depends on the "C-rate" of the cell chemistry. How quickly can the cells discharge without damaging themselves too much?

    In theory, Tesla could use different cell chemistry on some packs with higher power density, but lower energy density... So you could get same max power from a lower capacity pack.
    But my guess, is that some configurations were the same chemistry with less cells, so therefore the motor has to be power limited to protect the pack. That could be a decision for cost / price reasons.

    East coaster hoping the 75kw version can be delivered first since that's my primary upgrade preference...the battery.

    The configurations are the same chemistry and they are not all pulling at the same C-rates as the performance version.

    As far as I know the non-performance versions are not limited by the battery or cell chemistry. Likely it's about tradeoffs between acceleration, motor size, range, and the life of the battery.
