The most plausible explanation for dropping the YSR is that the pending $7k GREEN Act tax credit is going to be approved and will be announced imminently. This will bring the effective cost down of the YLR down to $42K which is only $3K more than the last YSR price. Most consumers in the market for a Tesla are going to go for the LR at this price and it doesn’t make sense from a business or manufacturing point of view to offer the SR. Unfortunately, this doesn’t help those who don’t have the mimimim $7K tax liability needed to take full advantage of the tax rebate. Realistically (and I’m not saying this makes it right!), Tesla is not marketing to those demographics anyway. EV’s are still too expensive for most of the population. However, now the race is really on with other manufacturers to provide affordable EV’s for the masses, within a couple of years the landscape will be completely different and the average person will be driving a sub $25K EV with 300+ miles of range.
