I think Elon's tweet here, pretty much confirms the 75 kWh battery. Of course, it is not a 100% confirmation but it is more than speculation at this point.Just asked because as far as I am aware, it is only speculation at this point that there will even be a Model 3 75D.
Hi, @SureValla. If you give me the details you have entered, I will have a look but your estimate shouldn't have moved sooner. The production start date for dual-motor in Eastern Time states was 1 Dec 2017 before the latest update. It is now 22 Jan 2018.
