Tesla to begin Model S, X P90DL to P100D performance upgrade on eligible cars
More than a year after Tesla first introduced its flagship Model S and Model X P100D, and offered P90DL owners the opportunity to transform their cars to “World’s quickest production car” status, the California-based electric car maker is finally making good on its promise on the performance upgrade.
“Tesla customers who have ordered a P90D Ludicrous, but not taken delivery, can upgrade to the 100 kWh pack for $10,000. Existing P90D Ludicrous owners can also upgrade to a 100 kWh pack, but for $20,000, as their used 90 kWh pack will have to be recycled.” said Tesla in a blog post from August 2016.
Now, fourteen months later, Tesla P90DL owners are reporting service appointments being made for the 90 kWh to 100 kWh performance battery pack upgrade, with first installs taking place as early as next week.
Tech_Guy who first discovered Tesla’s performance-limiting algorithm, something the company would later remove through an over-the-air software update, is unsurprisingly first in line for the P90DL to P100D upgrade.
The following invoice shows a line item for a 100 kWh battery pack upgrade with part number 1135371-00-A. The upgrade is being made available to select P90DL vehicles that are equipped with the revised front fascia, air suspension and battery packs that have the proper connector (Tesla is known to make several battery revisions for the same vehicle model, sometimes requiring different hardware between packs).
The performance retrofit is priced at $20,000 for P90DL owners that have already taken delivery of the vehicle when the upgrade announcement was first made.Beyond the increase in battery capacity from 90 kWh to 100 kWh, and addition of Ludicrous plus mode, the upgrade package will also replace the P90DL’s “next gen seats” with current production premium seats that have been crash tested with the more powerful 100 kWh battery pack.
DON’T MISS: What makes the Tesla 100 kWh battery so different?
The communication by Tesla serves as relief to anxious buyers of the performance upgrade, many of whom were placed on an interest list for nearly a year, and initially told that the retrofit was yet to be released. “We are diligently working on it, but no release date is currently available. You remain on the interest list, hence you will be contacted as soon as details become available.” said Tesla in Jan of 2017.
Tesla did not provide reasons for the year-long delay, but one can speculate that it had to do with the initial production shortfall of the company’s largest 100 kWh battery pack. CEO Elon Musk noted in October 2016 during a company’s earnings call that the 100 kWh battery production line was one of his top three priorities. All the while, the company would continue to dump its inventory of Model S and X P90D vehicles, before finally discontinuing the 90 kWh battery pack and P90DL variant, thus making the P100D with Ludicrous+ its highest performing model.

Tesla called ‘biggest meme stock we’ve ever seen’ by Yale associate dean

Tesla (NASDAQ: TSLA) is being called “the biggest meme stock we’ve ever seen” by Yale School of Management Senior Associate Dean Jeff Sonnenfeld, who made the comments in a recent interview with CNBC.
Sonnenfeld’s comments echo those of many of the company’s skeptics, who argue that its price-to-earnings ratio is far too high when compared to other companies also in the tech industry. Tesla is often compared to companies like Apple, Nvidia, and Microsoft when these types of discussions come up.
Fundamentally, yes, Tesla does trade at a P/E level that is significantly above that of any comparable company.
However, it is worth mentioning that Tesla is not traded like a typical company, either.
Here’s what Sonnenfeld said regarding Tesla:
“This is the biggest meme stock we’ve ever seen. Even at its peak, Amazon was nowhere near this level. The PE on this, well above 200, is just crazy. When you’ve got stocks like Nvidia, the price-earnings ratio is around 25 or 30, and Apple is maybe 35 or 36, Microsoft around the same. I mean, this is way out of line to be at a 220 PE. It’s crazy, and they’ve, I think, put a little too much emphasis on the magic wand of Musk.”
Many analysts have admitted in the past that they believe Tesla is an untraditional stock in the sense that many analysts trade it based on narrative and not fundamentals. Ryan Brinkman of J.P. Morgan once said:
“Tesla shares continue to strike us as having become completely divorced from the fundamentals.”
Dan Nathan, another notorious skeptic of Tesla shares, recently turned bullish on the stock because of “technicals and sentiment.” He said just last week:
“I think from a trading perspective, it looks very interesting.”
Nathan said Tesla shares show signs of strength moving forward, including holding its 200-day moving average and holding against current resistance levels.
Sonnenfeld’s synopsis of Tesla shares points out that there might be “a little too much emphasis on the magic wand of Musk.”
Elon Musk just bought $1 billion in Tesla stock, his biggest purchase ever
This could refer to different things: perhaps his recent $1 billion stock buy, which sent the stock skyrocketing, or the fact that many Tesla investors are fans and owners who do not buy and sell on numbers, but rather on news that Musk might report himself.
Tesla is trading around $423.76 at the time of publication, as of 3:25 p.m. on the East Coast.

Tesla makes big change to Full Self-Driving doghouse that drivers will like
Now, it is changing the timeframe of which strikes will be removed, cutting it in half. The strikes will be removed every 3.5 days, as long as no strikes are received during the time period.

Tesla is making a big change to its Full Self-Driving doghouse that drivers will like.
The doghouse is a hypothetical term used to describe the penalty period that Tesla applies to drivers who receive too many infractions related to distracted driving.
Previously, Tesla implemented a seven-day ban on the use of Full Self-Driving for those who received five strikes in a vehicle equipped with a cabin camera and three strikes for those without a cabin camera.
It also forgave one strike per week of Full Self-Driving use, provided the driver did not receive any additional strikes during the seven-day period.
Now, it is changing the timeframe of which strikes will be removed, cutting it in half. The strikes will be removed every 3.5 days, as long as no strikes are received during the time period.
The change was found by Not a Tesla App, which noticed the adjustment in the Owner’s Manual for the 2025.32 Software Update.
The system undoubtedly helps improve safety as it helps keep drivers honest. However, there are definitely workarounds, which people are using and promoting for monetary gain, and you can find them on basically any online marketplace, including TikTok shop and Amazon:
🚨 Seeing more and more devices like this land on various online marketplaces including TikTok shop and Amazon
These devices are NOT to be used when operating Tesla Full Self-Driving and I’d love to see Tesla take action here.

People are marketing the product as an FSD cheat device, which the cabin-facing camera will not be able to detect, allowing you to watch something on a phone or look through the windshield at the road.
The safeguards implemented by Tesla are designed to protect drivers from distractions and also protect the company itself from liability. People are still using Full Self-Driving as if it were a fully autonomous product, and it is not.
Tesla even says that the driver must pay attention and be ready to take over in any scenario:
“Yes. Autopilot is a driver assistance system that is intended to be used only with a fully attentive driver. It does not turn a Tesla into a fully autonomous vehicle.
Before enabling Autopilot, you must agree to “keep your hands on the steering wheel at all times” and to always “maintain control and responsibility for your vehicle.” Once engaged, Autopilot will also deliver an escalating series of visual and audio warnings, reminding you to place your hands on the wheel if insufficient torque is applied or your vehicle otherwise detects you may not be attentive enough to the road ahead. If you repeatedly ignore these warnings, you will be locked out from using Autopilot during that trip.
You can override any of Autopilot’s features at any time by steering or applying the accelerator at any time.”
It is good that Tesla is rewarding those who learn from their mistakes with this shorter timeframe to lose the strikes. It won’t be needed forever, though, as eventually, the company will solve autonomy. The question is: when?

Elon Musk teases the capabilities of the Tesla Roadster once again

Elon Musk has once again teased the capabilities of the Tesla Roadster, fueling the anticipation that many have for the vehicle, despite it still having no public production or delivery date.
The Roadster is among the most anticipated vehicles in the automotive sector currently, and as Tesla has teased its capabilities, from a lightning-fast 1.1-second 0-60 MPH acceleration to potential hovering with cold-gas thrusters, people are eager to see it.
Although the design seemed to be finalized, there was still more work to be done. Earlier this year, as Tesla was showcasing some of the Roadster’s capabilities to Musk, he stated that it was capable of even more.
This pushed back its production date even further, much to the chagrin of those who have been waiting years for it.
Musk continues to tease us all, and as we sit here waiting hopelessly for it to be revealed, he said today that it is “something special beyond a car.”
The new Roadster is something special beyond a car
— Elon Musk (@elonmusk) September 17, 2025
Musk’s words were in response to a video posted by Tesla China, showing the Roadster in a new promotional video created by a fan.
The Roadster was planned to be released in 2020, but here we are in 2025, and there is still no sign of the vehicle entering production. However, Tesla did say earlier this year that it would host a demo event for the Roadster, where the company would showcase its capabilities.
Lars Moravy said earlier this year:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.”
Tesla exec gives big update on Roadster, confirming recent rumor
The delays have been attributed to “radically increased design goals” for the vehicle, which have, without a doubt, improved its capabilities, but at the same time, we just want to know if it’s ever going to come.
Tesla can always make it “better,” but at what point do you say, “Okay, it’s time to show this thing off.” They could always build another, even more capable supercar in the next ten years.
