Elon Musk confirms new Tesla MCU can be retrofitted, but new software will provide accelerated rendering
In a recent tweet, Elon Musk confirmed that Tesla Model S and Model X owners whose vehicles are equipped with older Media Control Units could be retrofitted with the company’s new x86_64-based MCU. Musk further stated that a software upgrade for NVIDIA Tegra-3-powered vehicles will be released, which would make a “big difference” in the performance of older media control units.
Musk’s recent Twitter update was a response to one of his followers on Twitter, who asked if Tesla’s new MCU could be retrofitted into Model S and X vehicles that were released last year. Musk issued a quick response to the Tesla enthusiast’s inquiry, stating that a hardware upgrade would definitely be an option for owners of the all-electric luxury sedan and SUV.
“Yes, you can upgrade hardware, although we also wrote software to accelerate rendering on old MCU. Coming out soon & makes a big diff.”

Elon Musk’s recent Twitter update bodes well for all Model S and Model X owners, especially since even those who opt out of the retrofit option are still set to see improvements in the vehicle’s touchscreen display.
The capability to retrofit Tesla’s new, improved media control unit to older vehicles will likely be a welcome option for Model S and Model X owners. The new MCU, after all, exhibits a noticeable speed and performance improvement over its predecessor. As we noted in a recent report, a controlled test of Tesla’s old and new MCU showed that the new media control unit is roughly twice as fast as the company’s NVIDIA Tegra-3-powered MCU.
The test, which was conducted by YouTube channel My Tesla Adventure, featured two Tesla vehicles that were connected to the same Wi-Fi network. During the test, the newer MCU was able to load destination information in 9.27 seconds compared to the older unit’s 20.73 seconds. Manual map navigation is greatly improved as well, with the new MCU being far more responsive than the older unit.
The electric cars’ built-in internet browser, one of the old MCU’s most notable flaws, was also greatly improved. In the controlled test, the new media control unit was able to load the Tesla webpage from Google.com in 12.10 seconds, while the old MCU had to take as much as 48.32 seconds to load the same page.
Tesla’s updates to the Model S and Model X’s media control unit was previously confirmed by a Tesla spokesperson earlier this month. According to the spokesperson, the updates to the Model S and X’s MCU are part of Tesla’s efforts to steadily improve its fleet through minor hardware and software upgrades. It should be noted, however, that Tesla’s MCU update is strictly for the electric cars’ media control unit; and thus, not related to the vehicle’s Autopilot capabilities.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.

This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade
Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.
Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.
Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.
Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error.
More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report.
Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.
Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.
Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.
“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
