All SR+ orders going forward are LFP in United States. If you have a Vehicle that says 262 Miles when purchased its LFP Vehicle. It was 252 miles before a software update where Normally the SR+ Vehicles have 55.6 KWh Battery. Now the Available Battery Before was 50 KWh, where the car kept 5KWh in Reserve. With the new Update it Only Keeps 2Kwh In reserve, so that they can say the EPA Range in 262 Miles Instead of 252 Miles before the Update. NCA Vehicles have a range of 263 Miles with a 5Kwh Reserve. Because of the New Battery Chemistry and the Fact they need to but more batteries in terms of both Volume and Weight into the Vehicle, the build is 250 Pounds heavier then the NCA Build. People still seem to be Enjoying the Vehicles the same and can't really notice a difference. And the perks of having a overall longer lasting battery in terms of Longevity and having more Recharge cycles with being able to Charge to 100% without as much damage as a NCA build is a big plus. LFP Batteries don't seem to do well in the Cold weather though. so Its a bit of a trade of, it basically what works best for you and your situation,.
