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).

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 Semi finally has an FSD timeline and it’s waiting on the Cybercab
Elon Musk told investors Semi self-driving should start working by early 2027, per today’s earnings.
During Wednesday’s’ Tesla Q2 earnings call, an analyst asked Elon Musk when Tesla would look at autonomy for the Semi. His answer set a real timeline for the first time, noting that self-driving on the Tesla Semi is expected to start working “around the end of this year or early next year”.
Musk framed the delay as a matter of priority, not capability. Tesla’s self-driving team is currently focused on Model 3, Model Y, and Cybercab, the vehicles that make up the overwhelming majority of Tesla’s fleet. Since Semi trucks on the road remain a small fraction of that total even after the recent Nevada factory ramp, Musk said it made more sense to keep the software team’s attention on what he called “the march of nines of safety” for the higher volume vehicles first. Autonomous Semi development is “taking a bit of a backseat for the next six months or so,” he said, before adding that it “will definitely be working next year and in time for the scale-up to high production of the Tesla Semi.”

The timeline lines up with what’s already been showing up on public roads. In June, a Tesla Semi was spotted in Sunnyvale wearing a full validation rig, the same rooftop sensor array Tesla mounts on vehicles ahead of an FSD milestone.
A second unit was seen near Fremont days later with a matching camera suite and lens washers. Separately, Tesla analyst Nic Cruz Patane posted video this month of the production Semi’s exterior camera array, ten AI4 based units built directly into the truck rather than added later.

Musk also gave the reason autonomy on the Semi matters in the first place, a persistent shortage of qualified truck drivers. “There is a really serious shortage of truckers,” he said on the call, framing a self-driving Semi as important both for addressing that shortage and for improving safety and comfort for the drivers running the truck today.
The timing also tracks with the Semi’s production reality. Tesla’s Q2 shareholder letter, dropped language promising the Semi would reach volume production this year. Musk pointed to 4680 battery cell output as the near-term constraint on Semi and Cybercab production. A software timeline landing in early 2027 gives Tesla’s autonomy team room to work while the hardware ramp catches up behind it.
It’s worth nothing that this isn’t necessarily a promise the Semi ships driverless next year. Musk’s own language, self-driving “working” by early 2027, describes internal validation catching up to hardware already riding on every production truck, not a public unsupervised rollout.
Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.
The earnings results come after Tesla reported a massive beat on vehicle deliveries for the second quarter, delivering 489,126 vehicles and building 451,758 cars during the three-month span.
This was a major shock for those on Wall Street as they anticipated somewhere around 400,000 deliveries for the quarter, and showed Tesla still has plenty of demand for its vehicles around the world and in the U.S. despite losing the $7,500 EV Tax Credit last year.
Tesla Q2 2026 Earnings Results
- Non-GAAP EPS – $0.33 reported vs. $0.53 expected
- Revenues – $28.236 billion reported vs. $26.4 billion expected
- Free Cash Flow- -$1.092B
- Profit -$ 4.751B
Tesla (beat/missed) analyst expectations, so the market response to the company’s quarter is what we will look for next.
Tesla shares closed today down just over 1 percent, trading at $374.01.
In the past, it has been anyone’s guess with what Tesla shares will do after they report earnings. Strong quarters have resulted in sharp drops, while lackluster quarters have seen the stock shoot up considerably.
Tesla will hold its Q2 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.

Tesla is about to make parking in busy parking lots at businesses and other points of interest less stressful than ever by allowing drivers more control over where they park and how, CEO Elon Musk confirmed on X.
Tesla has been working to improve the parking performance of vehicles utilizing the Full Self-Driving suite, but now it is looking to add more customization, allowing drivers to choose the specific space they park in, but also potentially the orientation the car pulls into the spot:
It’s coming soon
— Elon Musk (@elonmusk) July 21, 2026
Musk has reiterated on X twice over the past several weeks that Tesla is working to make things with the FSD suite based more on the driver’s specific preferences and behaviors that were seen in past drives.
Essentially, it sounds like if you tend to park away from a business to avoid other vehicles, Tesla FSD will soon recognize that preference of yours and start parking further away as well. Additionally, the prospect of assigned parking spaces has been something many owners have voiced concerns about.
Living in a community with assigned parking spaces makes using FSD incredibly difficult as it will rarely park in the correct spot when there are so many to choose from. This is also pertinent in work settings where there are sometimes assigned parking spaces.
The updates to Tesla’s Full Self-Driving suite in terms of listening to driver preferences with parking are also extending to routing. Tesla announced yesterday that with the release of its 2026 Summer Update, it was adding Automatic Navigation and Preferred Routes:

Tesla has always maintained the idea that any human input is bad input, and that, ideally, Tesla Full Self-Driving will always make the right decision. Of course, this is all in theory, but the issue is that so many of Tesla’s interventions have come because it does something that is not necessarily wrong, but perhaps not what the driver would prefer.
Taking these preferences into account will help Tesla alleviate some of the potentially unnecessary interventions that drivers perform.
