Elon Musk has provided new details about Tesla’s Media Control Unit (MCU) retrofits for vehicles that are equipped with older infotainment systems. According to the CEO, MCU1 to MCU2 retrofits may start in a few months, though he does not personally recommend it, especially considering its estimated $2,000 cost. Musk has instead suggested that Tesla will release an update to older cars that can optimize the performance of their existing MCUs.

Musk’s recent statements were shared on Twitter while the CEO was interacting with Tesla owners, some of whom owned MCU1-equipped vehicles. The limitations of the older hardware have become more prominent over time, particularly as Tesla rolled out media-heavy features such as the Tesla Theater and the Tesla Arcade. Similar to older hardware in mobile devices, MCU1 vehicles have become slower compared to the company’s newer vehicles like the Raven Model S and X, as well as the Model 3.

Elon Musk has previously stated that MCU1 retrofits would be offered to owners whose vehicles are still equipped with older hardware. The CEO confirmed this following the initial rollout of MCU2 vehicles, and the idea was reiterated after the release of the company’s new Tesla Arcade titles. That being said, a number of Tesla owners have been informed by local service centers that an MCU1 to MCU2 retrofit was not possible.

Tesla Infotainment Upgrade

For the uninitiated, Tesla’s MCU1 is equipped with an Nvidia Tegra 3 processor, which is capable but a tad slower than its newer sibling. Meanwhile, the MCU2 runs on an Intel Atom E800 series chip and comes with a faster browser. The unit also renders videos with sound, giving it the capability of running new features such as the Tesla Theater, which includes video streaming apps such as Netflix and YouTube, as well as video games in Tesla Arcade. All Tesla Model 3s run on MCU 2, as well as Model S and Model X units purchased after March 2018. Customers who bought their Model S and X prior to March 2018 use the MCU1.

Many Tesla owners whose vehicles are equipped with MCU1 have been clamoring for an update to avail of features only enjoyed by those using the newer system. Tesla has not left those on MCU1 in the dark and has rolled out several updates to improve the performance of the older infotainment systems. That being said, the gap between the actual capabilities of Tesla’s MCU1 hardware and its MCU2 features such are growing, and it has pretty much reached the point where the infotainment systems of older vehicles are significantly slower than those in newer cars.

In a way, Elon Musk’s recent statements hint that Tesla’s current priority is the rollout of its Hardware 3, which is essential for its Full Self-Driving initiatives. Retrofits for HW2.5 vehicles have already begun, and HW2 vehicles are expected to follow soon. HW3 is Tesla’s custom-designed computer that replaces the old Nvidia computer used for HW 2.5. As noted by Tesla during its Autonomy Day presentation, Hardware 3 was specifically built to achieve true Full Self-Driving capabilities and can enhance the electric car’s processing capability by as much as 1,000 percent.

Nevertheless, it would be wise for Tesla to start rolling out its MCU1 retrofits for older vehicles, even if it’s later than expected. Considering that Tesla owners have shown a willingness to pay for the retrofit, and the CEO himself has confirmed that the upgrade is possible, it is in both Tesla and its customers’ best interest to make sure the vast majority of its fleet are able to enjoy the best that the company has to offer — even if it’s just for infotainment purposes.

A curious soul who keeps wondering how Elon Musk, Tesla, electric cars, and clean energy technologies will shape the future, or do we really need to escape to Mars.

The Tesla Model Y has become the most common car on Norwegian roads. This is a remarkable achievement for the all-electric crossover, which has also commanded the top spot in Norway’s vehicle sales rankings for several years running.

Model Y Domination

As per vehicle registration figures tracked by the Norwegian Road Traffic Information Council (OFV), there were 68,378 Model Ys with Norwegian license plates at the end of March/beginning of April 2025. In recent weeks, the Model Y passed more than 70,000 registrations, as per a report from Elbil24.

With the Model Y now becoming the most common car in Norway, the Toyota Rav4 now stands in second place, followed by the Nissan Leaf, the Volkswagen Golf, and the Toyota Yaris. The Model Y also topped the country’s vehicle registration rankings for the last three years, and it set a record for selling the most vehicles in a year in 2023, breaking the Volkswagen Beetle’s record that has stood since 1969.

Possibly More Momentum

It is undeniable that the Tesla Model Y has helped Norway push its electric vehicle transition. As of date, electric vehicles now account for 28% of the Norwegian car fleet, a notable portion of which is comprised of the all-electric crossover.

While the Model Y’s achievements in Norway have been impressive, the vehicle could expand its reach into the country even more this year. Tesla, after all, has been aggressively pushing the new Model Y to consumers, with the company offering a zero percent interest promotion for the vehicle. These efforts, as well as the new Model Y’s improved features, should make the vehicle even more compelling to Norwegian car buyers this year.

Tesla Board Chair Robyn Denholm has issued a stern correction to The Wall Street Journal after the publication posted a report alleging that the electric vehicle maker’s Board of Directors opened a search for a new CEO to replace Elon Musk.

Denholm’s comments were posted by Tesla on its official account on social media platform X. 

The WSJ’s Allegations

Citing people reportedly familiar with the discussions, the WSJ alleged that Tesla Board members reached out to several executive search firms to work on a formal process for finding Elon Musk’s successor. The publication also alleged that tensions had been mounting at Tesla due to the company’s dropping sales and profits, as well as the time Musk has been spending with DOGE.

The publication also alleged that Elon Musk had met with the Tesla Board about the matter, and that members told the CEO that he needed to spend more time on Tesla. Musk was reportedly instructed to state his intentions publicly as well. The CEO did not push back against the Board, the WSJ claimed. 

Elon Musk did announce that he is stepping back from his day-to-day role at the Department of Government Efficiency during the Tesla Q1 2025 earnings call. Musk’s announcement was embraced by Tesla investors and analysts, many of whom felt that the CEO’s renewed focus on the EV maker could push the company to greater heights.

Tesla and Musk’s Response

In response to The Wall Street Journal’s report, Tesla’s official account on X shared a comment from its Board Chair. In her comment, Denham noted that the WSJ‘s report was “absolutely false.” She also highlighted that Tesla had communicated this fact to the publication before the report was published, but the Journal ran the story anyway.

“Earlier today, there was a media report erroneously claiming that the Tesla Board had contacted recruitment firms to initiate a CEO search at the company. This is absolutely false (and this was communicated to the media before the report was published). The CEO of Tesla is Elon Musk and the Board is highly confident in his ability to continue executing on the exciting growth plan ahead,” Denholm stated.

Elon Musk himself commented on the matter, stating that the publication showed an “extremely bad breach of ethics” since the report did not even include the Tesla Board of Directors’ denial of the allegations. “It is an EXTREMELY BAD BREACH OF ETHICS that the WSJ would publish a DELIBERATELY FALSE ARTICLE and fail to include an unequivocal denial beforehand by the Tesla board of directors!” Musk wrote in a post on X.

In a conversation with the New York Post, White House Chief of Staff Susie Wiles stated that Tesla and SpaceX CEO Elon Musk is no longer working from the West Wing.

As per the Chief of Staff, Musk is still working for DOGE—as a remote worker, at least.

Remote Musk

In her conversation with the publication, Wiles stated that she still talks with Musk. And while the CEO is now working remotely, his contributions still have the same net effect. 

“Instead of meeting with him in person, I’m talking to him on the phone, but it’s the same net effect,” Wiles stated, adding that “it really doesn’t matter much” that the CEO “hasn’t been here physically.” She also noted that Musk’s team will not be leaving.

“He’s not out of it altogether. He’s just not physically present as much as he was. The people that are doing this work are here doing good things and paying attention to the details. He’ll be stepping back a little, but he’s certainly not abandoning it. And his people are definitely not,” Wiles stated.

Back to Tesla

Musk has been a frequent presence in the White House during the Trump administration’s first 100 days in office. But during the Q1 2025 Tesla earnings call, Musk stated that he would be spending substantially less time with DOGE and substantially more time with Tesla. Musk did emphasize, however, that DOGE’s work is extremely valuable and critical.

“I think I’ll continue to spend a day or two per week on government matters for as long as the President would like me to do so and as long as it is useful. But starting next month, I’ll be allocating probably more of my time to Tesla and now that the major work of establishing the Department of Government Efficiency is done,” Musk stated.
