The difference between LR vs Performance in an S and X isn’t just about Ludicrous Plus (what you described needing preheated for max benefit) . The Performance S and X have significantly more power and acceleration at any speed over the regular versions without having the battery preheated. We leave our S in Ludicrous all the time because it doesn’t use more power until you stomp on it. To get the last few percent of performance you can preheat in Ludicrous Plus but the Launch and regular Ludicrous work all the time, even cold and with the new software update the car doesn’t need to be lowered. The 3 and Y long range cars only get beat by the Performance 3/Y immediately off the line but at any other speed they are virtually the same. The Performance 3 and Y are just software bumped up Long Range cars hence the $8k bump, you still can get the tire/wheel/suspension/brake package to look the racer part. The $20k added on the S and X is somewhat more justified because it’s got beefier components, not just software and it is also always there. If you don’t care about power off the line in a 3/Y the Performance version doesn’t matter. A Performance S will still make a regular S or X, 3 or Y look sluggish no matter the battery temperature or suspension settings, slightly more so if the battery is warm.
