The Tesla "Plaid" version is a simple luxury for those that can afford it. $40,000 and the only difference is one accelerates quicker than the other. That's always been the case with the "Performance" version of Tesla. Especially on the S & X, Tesla charges astronomically for that acceleration. But, was originally a $10,000 premium. Then went to $20,000, then $30,000, then $40,000. It think it was up to $50,000 at one point, But, as demand declined, it came back down. Used to be $20,000 for the "P" version, then another $10,000 or $20,000 for the "Ludicrous" mode. In the past, you got red painted calipers included, as well as a spoiler that you can buy on E-bay for $89.00. But other than that, no other difference between the two.
The new Long Range version however, has "Insane" mode, which was the original mode offered when the P85D came out. It's 3.1 0-60 is basically exactly the same as the P85D or P90D was. I had one and used it as a party trick to show off to new passengers, who were shocked each time they felt it. It was $20,000 when I bit the bullet and bought it. Now, it's included for free with the Long Range Version. Can't imagine it wouldn't still shock passengers that have never felt a car than can do 0-60 in 3 seconds, which is faster than just about any car on the planet as it is.
1.99 seconds is beyond insane, yes. Actually, it's more like 2.2 - 2.3 seconds in real world driving without the "roll-out" and being in perfect conditions on a sticky race track, and after letting the car warm up and lower itself and engage "launch mode" etc. Still incredible no doubt. So, when that Ferrari or Lambo pulls up to you at the red light of an intersection and wants to race, you'll have to politely ask "would love to, but can you give me 10-15 minutes for my car to set itself up for launch mode?" Yeah, not going to happen. For the rare few that go to a drag strip regularly, then it clearly has all the value in the world. Other than the $2.4 million dollar Rimac Rivera, which does 0-60 in 1.8 and the 1/4 mile in 8.6 seconds, there won't be a production car at the track that can beat you. But, for those that will never take their car to a race track, I personally think "Insane Mode" offers nearly the same "wow" factor to passengers, just as it did in 2015 when the P85D / P90D came out.
While I can afford it, the reason I can afford it is partially attributed to being smart throughout the years. The sensible side in me can't bring myself to spend $40,000 simply to accelerate 0.8-0.9 seconds faster to 60. I NEVER used the P90D's performance except when demonstrating it to passengers. And 3 seconds 0-60 gave me a headache as it was. I only drove the Plaid for a short time, but can't imagine what 2.2 - 2.3 second repeated launches would do to my head!! Sure, it's a hell of a "WOW" factor. But, then for most, it never gets used beyond those demonstration moments. And the original Insane mode at 3.0-3.1 was always a hell of a "WOW" factor as it is. So to get that at no extra cost now, that's a pretty good deal. Even my current 2019 LR Raven at 3.8 0-60 is still far more than I ever use on the road. I think I've floored the car maybe twice since I bought it.
All depends on the user and how much they will actually use it. Most that I know with Tesla's say they never use it and just got it because it was the best of the best available, rather than because it was an option they would actually benefit from.
There's never been a dispute about Tesla's performance. They've set the bar and continued to raise it. 6 years in, there are still buyers willing to pay that $40,000 price tag simply for quicker acceleration, so Tesla will keep charging it as long as they can get it. Again, as with the 2019, eventually those buyers fade and the price comes down into the $10,000 to $20,000 range, until they release something new again.
With most high-end cars, when you purchase the "Performance" version of it (Mercedes AMG, BMW M, Audi RS, etc), that $40,000 gets you quite a bit more than just acceleration (sportier bodies, better wheels, better brakes, better suspension, spoilers, usually some upgraded interior pieces, etc). At $10,000 to $20,000, not so bad for what Tesla offers. At $40,000, regardless of the fact that it does accelerate quicker than any other production car, sending the kids to college or getting them a Model 3 for that $40,000 just seems to be a higher value!! LOL.
