I know we've seen some small increases in performance for the Performance models, but Tesla just sent out an email that both the Model S and X base models got their 0-60 times dropped by a full second via a S/W upgrade. That's a huge difference! Right now I'm sure it'll be a nice differentiator between them and the model 3, but there doesn't seem like many reasons the Model 3 won't be able to get a nice performance boost down the road via OTA update.
