I don't work at Tesla, but I think it's pretty obvious that they're going to produce and deliver as many Performance and AWD models as possible before they think about RWD. They want to get the highest margin cars out of the door as quickly as possible (especially before the end of the month/quarter). As long as there continues to be solid backlog/demand for P & AWD, they'll stay on that course.
