Tesla to allow MCU upgrade for older Model S and X for better gaming experience
Elon Musk dropped several updates on Twitter over the weekend, covering several aspects of Tesla’s vehicles. Among these are the release date for firmware Version 10, the unveiling of the Tesla Pickup Truck, some games that are coming to the Tesla Arcade, and even a Media Control Unit (MCU) retrofit that will be made possible for older Model S and Model X vehicles.
Musk’s comments come amidst interactions on Twitter about the Tesla Arcade’s new titles, which include exciting games such as Cuphead and Fallout Shelter. While responding to a Tesla owner who stated that he would be happy to pay for an MCU and LTE upgrade for his vehicle, Musk responded that it would indeed be possible to retrofit older Model S and X units with company’s newer MCUs.
Providing MCU upgrade options for older Model S and Model X will further emphasize the idea that Teslas are vehicles that only improve over time. It would, for one, allow even the company’s older vehicles to gain access to some of the newest features found in cars produced today, including the growing library of titles in the Tesla Arcade.
MCUs in Model S and Model X vehicles produced prior to March 2018 are equipped with 2011-era NVIDIA Tegra-3 chips, which worked well for the vehicles’ basic features but lacked in smoothness and speed compared to the Model 3’s Intel-powered MCU. Tesla introduced a newer, faster MCU for the Model S and Model X in March 2018, partly as a way to ensure that the media units of its vehicle lineup share the same speed and performance.
While confirming the rollout of the newer hardware, Tesla noted then that the newer media units were part of the company’s consistent drive to steadily improve its vehicles. In a statement to Teslarati, the electric car maker also explained that the new MCUs would not dramatically affect the user experience of its vehicles.
Tesla was able to buffer the performance discrepancy between its older and newer MCUs by rolling out a software update that optimized the performance of pre-March 2018 media units. Inasmuch as this made the user interface of MCU1 vehicles almost as smooth as the newer, Intel-powered units, later features such as the Tesla Arcade were eventually made exclusive to cars equipped with post-March 2018 MCUs.
It should be noted that Elon Musk has mentioned an MCU retrofit option for older Model S and Model X vehicles in the past. “Yes, you can upgrade hardware, although we also wrote software to accelerate rendering on old MCU. Coming out soon & makes a big diff,” Musk tweeted as a response to a Tesla owner who asked if he could retrofit his vehicle with the newer media unit. With his recent comments, perhaps an MCU retrofit for older vehicles would indeed be in order.
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.
Tesla is starting to prepare for the launch of the Optimus robot in its smartphone app, new coding strings show. Elon Musk has referred to Optimus as what will be the greatest-selling product of any kind of all time, and now, Tesla is getting ready for its launch.
Tesla’s smartphone app had several first-time mentions of the Optimus program, according to Tesla App Updates, who intially reported on the appearance. Here’s what they found:
A Dedicated “Robot” Phone Key Authentication
Tesla is working on a Bluetooth Low Energy, or BLE, authentication that is specifically for robots. This does not only apply to Optimus, though, as Robotaxi, which is Tesla’s autonomous ride-hailing platform, might also identify vehicles within the fleet as robots as well.

Essentially, pairing your phone as a key to anything Tesla identifies as a robot to a “whitelist” of authorized devices. Optimus, Robotaxi, or other products that fall into this category will only respond if the device trying to communicate with it is authorized.
This is a great security feature that will eliminate at least face-value and low-level threats.
Home Data Collection and System Alerts
This appears to be somewhat of a neural network for Optimus within your house. There will be a dedicated screen that asks for consent to collect both video and spatial data while Optimus performs in-home tasks. Everything from vacuuming, washing dishes, dusting, and other activities will be tracked.
There will also be a comprehensive alert system that will track everything from low battery to mechanical issues.
Other Changes
Most of the changes tracked in this particular app update are related to Tesla’s 2026 Summer Update, and include things such as image assets for new features, a preview of the new custom wraps feature, and other unique features.
