My guess as to whats going on.,.
SR+ is selling so well that they coverted all medium ranges into that by disconnecting some speakers and software locking the battery. Once they run out the model will discontinue.
They are only going to make two model 3 cars now:
SR with cloth interior: they will offer a battery unlock for $2,000 and will work on getting it cheaper to build so they don’t lose money on it. Either they keep making cost cuts or the price goes up.
Dual motor premium long range: the same car can be rwd, awd, or performance. Software upgrades and unlocks available for all trims so they can make more money later. $4k unlock front motor, $8k unlock performance.
