The refresh has an entirely new battery pack design (cooling, packaging, BMS boards, etc) with revised cell chemistry, and I would note, the chemistry has been changed over your existing S a few times and many times since my 2013 S. It's not the same "battery tech". The only thing believed to be the "same" is the 18650 metal container the cell is formed into.
Re: 500 mile range, that is indeed a game changer, and a compelling reason we have a Cybertruck tri motor reservation to replace our S.
I do currently have a Raven S. Have had several Model S's already. To Tesla's credit, yes, the Model S todays is absolutely a better car than the 2012 was and most in between. But, still looks almost exactly the same as my 2012 did.
I was in a similar boat to another poster above. Wasn't going to upgrade from my 2017. The thing that got me to do it was when they dropped the price by $10,000 overnight in 2019. At that point, I made the plunge and upgraded. The suspension was a big upgrade. But, the rest of it basically felt identical. My car "says" I'll get 360+ miles per charge. But Tesla has always been one to state range based on the best possible scenario (downhill with a tailwind, LOL). It appears that most others are stating range based on more realistic driving conditions. Plus, they adjust the range figure to your driving style. So when the car says 200 miles in range, you likely will get it. In the Tesla, I've never come close to 300 miles, let alone 360+. Not a knock on them, that's how they choose to market the car. That's fine. Just like they still reflect prices after government kickbacks (for those that qualify). I prefer the adjusted range figure to my driving as it's much more useful than a number that, for me and my driving style and conditions I drive under, is meaningless other than to show how much percentage of the battery I have left.
Anyway, the new Plaid is what, $130,000 now? Before adding FSD or anything else. Last year, with the $10,000 price reduction, plus the $10,000 Ludicrous option now included at no cost, a Performance version was right at $100,000 all inclusive. Now, add in $10,000 for FSD and you're pushing $40,000 more. Just can see $40,000 more in car. Sure, it's improved, but at $140,000, the Audi GT is looking pretty nice. States a much lower range, but the sister car, the Taycan has had owner's reporting that real world range far exceeds stated EPA range. At over $100K, I need to see something completely new and exciting in the garage. The Refreshed Tesla S unfortunately, doesn't get me there. I'm 100% certain, the price will drop on it after a couple of years.
