I received an email from Tesla about the, now available, update to bring Model 3 LR AWD from 4.4 sec 0-60 to 3.9. Yay, I guess. You'll need to have 2019.40.2 before the update can be installed. OK, I get all that HOWEVER... Log into your Tesla Account and select Upgrades to purchase. You can now also purchase upgrades from the Tesla app — download version 3.10.3 to access the Upgrades menu. Does this signal updates are now a chargeable item? Just checked. They want $2,000 for it.
