Have a 2020 Model X LR+. I also have a C7 Corvette. The "base" X has plenty of power. I would much rather have more range then more power. If a new model came out with more power, it would not interest me in an early upgrade. Now add an extra 100 miles of range and I would think about it. Even with 350 mile range "advertised" you are really only going to get @80%. So that is 280 miles and you are going to recharge before your get below 50 miles. So now you have 230 mile range. And when you do recharge you are not going to go over 80% because the last 20% will take too long. So now your charge up to 280 which will only give you @220 - 50 = 170 miles. So 400 miles 1 way with 1 charge is all you can do. Add an extra 100 miles to the range in real world = 80 + 64 = 144 miles or 544 miles 1 way with 1 charge. Big deal + gives you way more options in where to stop to charge. Range is king. 0-60 in 4.4 seconds is already plenty quick.
when you only going to get 280 @80% - do you mean that you assume people will drive it 80% before recharging or that's your experience with the "real world" range. just ordered an LR+ yesterday. Our MX 90D with 257 rated range never did over 200 and my MX 100D (2019 pre raven) never does more than 300. I plan to put in 22's on the LR+
