"More challenges than expected in developing plaid Model S, the new version of model S/X with revised interior, battery pack, internal electronics, PS5 level entertainment system, a lot of issues encountered, took quite a bit of development and make sure the new battery is safe. Trying to get all the details settled in the cars for the past few months. Making refinements and want start delivering by probably next month. Expecting high volume model S's in Q3. As we ramp out demand for the S/X will be quite high. We're going to aim to produce 2k S/X per week. It's a great car. Cost us a little less to produce but is a superior product"
