Tesla Model S/X gets updated MCU for faster, more responsive touchscreen display

Published

on

Tesla is reportedly using an improved MCU on newer versions of the Model S and X, replacing the aging NVIDIA Tegra-3 chip on the flagship sedan and SUV with a more powerful x86_64 processor. As could be seen in a side-by-side video comparing the performance and speed of the old and new media control unit, the updated hardware provides a smoother, faster, and more responsive experience on the Model S and X’s touchscreen.

The speed and fluidity, or lack thereof, of the Model S and X’s MCU has been a pain point for Tesla owners for a while, considering that the vehicles were equipped with 2011-era NVIDIA Tegra-3 chips. The shortcomings on the Model S and X’s interface became even more prominent when Tesla began switching from NVIDIA to Intel hardware to power its infotainment system, as evident on Model 3’s far more responsive touchscreen.

A Tesla spokesperson has confirmed with Teslarati that the company has recently introduced hardware changes to the onboard displays on the Model S and Model X. The update is part of the company’s overall initiative to introduce minor hardware changes and over-the-air software updates over time to continuously improve upon its vehicles. The latest update, unrelated to Autopilot, should not dramatically affect the user experience. Still, some new Tesla owners are reporting noticeable improvements in the browsing experience on the vehicle’s 17-inch touchscreen.

As could be seen in a recent collaboration video uploaded by YouTube’s My Tesla Adventure, the display of a recently-manufactured Model S seems to be on par with the speed and fluidity of the Model 3’s center touchscreen. In the side-by-side video, the Model S, which is equipped with an older Tegra-powered MCU, could be seen loading information a few seconds slower than the newer car. The touch panel on the newer Model S is also very vibrant, with the display featuring accurate color reproduction. A screenshot of the CPU information in the newer car also includes references to an x86_64 processor, something that is absent on older vehicles.

Apart from a smoother user experience, the Model S and X’s upgraded MCU also features a pleasant surprise — a usable web browser. As could be seen in a brief test by Model S owner and r/TeslaMotors member u/MaxKW, the browser on his Model S is actually usable. It’s still not on par with the speed of mobile devices like smartphones and tablets, but the internet browser is already far more useful than the web explorer installed in older cars.

An enhanced browser for the Model S and X was teased by Elon Musk in a tweet back in December. As we noted in a previous report, Musk, who was responding to one of his followers on Twitter, admitted that the browser on the Model S and X was “terrible.” He did, however, assure his followers that major upgrades for the web explorer would be rolling out “in a few months.”

“Yeah, it’s terrible. Had to upgrade old Linux OS and a bunch of drivers first. Major browser upgrades coming to all cars in a few months. Note, will be slower at first until code is optimized.”

Watch the side-by-side comparison of the old and new MCU for the Model S and X in the video below.

X account with 184 followers inadvertently saves US space program amid Musk-Trump row

Needless to say, the X user has far more than 184 followers today after his level-headed feat.

An X user with 184 followers has become the unlikely hero of the United States’ space program by effectively de-escalating a row between SpaceX CEO Elon Musk and President Donald Trump on social media.

Needless to say, the X user has far more than 184 followers today after his level-headed feat.

A Near Fall

During Elon Musk and Donald Trump’s fallout last week, the U.S. President stated in a post on Truth Social that a good way for the United States government to save money would be to terminate subsidies and contracts from the CEO’s companies. Musk responded to Trump’s post by stating that SpaceX will start decommissioning its Dragon spacecraft immediately. 

Musk’s comment was received with shock among the space community, partly because the U.S. space program is currently reliant on SpaceX to send supplies and astronauts to the International Space Station (ISS). Without Dragon, the United States will likely have to utilize Russia’s Soyuz for the same services—at a significantly higher price.

X User to the Rescue

It was evident among X users that Musk’s comments about Dragon being decommissioned were posted while emotions were high. It was then no surprise that an X account with 184 followers, @Fab25june, commented on Musk’s post, urging the CEO to rethink his decision. “This is a shame this back and forth. You are both better than this. Cool off and take a step back for a couple days,” the X user wrote in a reply.

Much to the social media platform’s surprise, Musk responded to the user. Even more surprising, the CEO stated that SpaceX would not be decommissioning Dragon after all. “Good advice. Ok, we won’t decommission Dragon,” Musk wrote in a post on X.

Not Planned, But Welcomed

The X user’s comment and Musk’s response were received extremely well by social media users, many of whom noted that @Fab25june’s X comment effectively saved the U.S. space program. In a follow-up comment, the X user, who has over 9,100 followers as of writing, stated that he did not really plan on being a mediator between Musk and Trump. 

“Elon Musk replied to me. Somehow, I became the accidental peace broker between two billionaires. I didn’t plan this. I was just being me. Two great minds can do wonders. Sometimes, all it takes is a breather. Grateful for every like, DM, and new follow. Life’s weird. The internet’s weirder. Let’s ride. (Manifesting peace… and maybe a Model Y.)” the X user wrote.

Tesla Cybertruck takes a bump from epic failing Dodge Charger

The Cybertruck seemed unharmed by the charging Charger.

There comes a time in a driver’s life when one is faced with one’s limitations. For the driver of a Dodge Charger, this time came when he lost control and crashed into a Tesla Cybertruck–an absolute epic fail. 

A video of the rather unfortunate incident was shared on the r/TeslaLounge subreddit.

Charging Charger Fails

As could be seen in the video, which was posted on the subreddit by Model Y owner u/Hammer_of_something, a group of teens in a Dodge Charger decided to do some burnouts at a Tesla Supercharger. Unfortunately, the driver of the Charger failed in his burnout or donut attempt, resulting in the mopar sedan going over a curb and bumping a charging Cybertruck.

Ironically, the Dodge Charger seemed to have been parked at a Supercharger stall before its driver decided to perform the failed stunt. This suggests that the vehicle was likely ICE-ing a charging stall before it had its epic fail moment. Amusingly enough, the subreddit member noted that the Cybertruck did not seem like it took any damage at all despite its bump. The Charger, however, seemed like it ran into some trouble after crashing into the truck.

Alleged Aftermath

As per the the r/TeslaLounge subreddit member, the Cybertruck owner came rushing out to his vehicle after the Dodge Charger crashed into it. The Model Y owner then sent over the full video of the incident, which clearly showed the Charger attempting a burnout, failing, and bumping into the Cybertruck. The Cybertruck owner likely appreciated the video, in part because it showed the driver of the Dodge Charger absolutely freaking out after the incident.

The Cybertruck is not an impregnable vehicle, but it can take bumps pretty well thanks to its thick stainless steel body. Based on this video, it appears that the Cybertruck can even take bumps from a charging Charger, all while chilling and charging at a Supercharger. As for the teens in the Dodge, they likely had to provide a long explanation to authorities after the incident, since the cops were called to the location.

Anti-Elon Musk group crushes Tesla Model 3 with Sherman tank–with unexpected results

Ironically enough, the group’s video ended up highlighting something very positive for Tesla.

Anti-Elon Musk protesters and critics tend to show their disdain for the CEO in various ways, but a recent video from political action group Led By Donkeys definitely takes the cake when it comes to creativity.

Ironially enough, the group’s video also ended up highlighting something very positive for Tesla.

Tank vs. Tesla

In its video, Led By Donkeys featured Ken Turner, a 98-year-old veteran who served in the British army during World War II. The veteran stated that Elon Musk, the richest man in the world, is “using his immense power to support the far-right in Europe, and his money comes from Tesla cars.” 

He also noted that he had a message for the Tesla CEO: “We’ve crushed fascism before and we’ll crush it again.” To emphasize his point, the veteran proceeded to drive a Sherman tank over a blue Tesla Model 3 sedan, which, of course, had a plate that read “Fascism.” 

The heavy tank crushed the Model 3’s glass roof and windows, much to the delight of Led By Donkeys’ commenters on its official YouTube channel. But at the end of it all, the aftermath of the anti-Elon Musk demonstration ended up showcasing something positive for the electric vehicle maker.

Tesla Model 3 Tanks the Tank?

As could be seen from the wreckage of the Tesla Model 3 after its Sherman encounter, only the glass roof and windows of the all-electric sedan were crushed. Looking at the wreckage of the Model 3, it seemed like its doors could still be opened, and everything on its lower section looked intact.

Considering that a standard M4 Sherman weighs about 66,800 to 84,000 pounds, the Model 3 actually weathered the tank’s assault really well. Granted, the vehicle’s suspension height before the political action group’s demonstration suggests that the Model 3’s high voltage battery had been removed beforehand. But even if it hadn’t been taken off, it seemed like the vehicle’s battery would have survived the heavy ordeal without much incident.

This was highlighted in comments from users on social media platform X, many of whom noted that a person in the Model 3 could very well have survived the ordeal with the Sherman. And that, ultimately, just speaks to the safety of Tesla’s vehicles. There is a reason why Teslas consistently rank among the safest cars on the road, after all.
