Details, like everything to do with SR, seem to be hazy. Has anyone confirmed that SR cars as actually delivered are any slower than SR+? Or was that one of the originally-intended differences like cloth seats that has since been dropped?
Tesla has not published a revised 0-60 speed on the SR yet so there is no official word on how fast the car is. And they have not software locked the car yet so there is no way to test it.
