As far as I have noticed, Tesla doesn't usually add anything to the Design Studio until it is available to build. So the AWD and Performance options may not even appear in the initial Design Studio. This may force those people who are high up in the reservation list but must have these options, to defer their order when invited to configure. But then how would those people know how long to defer etc?
