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

Tesla hit by Iranian missile debris in Israel
A Tesla in Israel absorbed a direct hit from missile debris, and the glassroof held.
On March 30, 2026, Lara Shusterman was in Netanya, Israel when Iranian ballistic missiles triggered air raid sirens across the city. While she remained in safety, her 2024 Tesla Model Y did not escape untouched. A heavy piece of missile debris struck the car’s massive glass roof, leaving a deep crater but without shattering. In a Facebook post to the Tesla Israel community the following morning, Shusterman described what happened: “The glass did not shatter into dangerous shards. She stopped the damage and pushed the metal part to the ground.” She closed by thanking Elon Musk and the Tesla team for building what she called “security and a sense of trust even in extreme situations.”
Netanya is a coastal city in central Israel, roughly 18 miles north of Tel Aviv and has been among the areas most frequently struck during Iran’s ongoing missile campaign, following coordinated U.S. and Israeli strikes on Iranian military infrastructure. Falling shrapnel from intercepted missiles is a common occurrence.

The incident is a testament to Tesla’s structural engineering. Tesla’s glass roof is designed to support over four times the vehicle’s own weight. That strength has shown up in real-world accidents too. In 2021, a Model Y in California was struck by a falling tree during a storm, with the glass roof holding firm and the cabin remaining intact. In another widely reported incident, a Tesla Model Y plunged 250 feet off the cliff at Devil’s Slide in California in January 2023, with all four occupants, including two young children, surviving.
Disturbing details about Tesla’s 250-foot cliff drop emerge amid initial investigation
Tesla officially launched sales in Israel in early 2021 and captured over 60 percent of Israel’s EV market in the first year. The brand’s foothold in Israel remains significant. Tens of thousands of Teslas are now on Israeli roads, making incidents like Shusterman’s easy to corroborate. On the same week her Model Y took the hit, the U.S. Space Force awarded SpaceX a $178.5 million contract to launch missile tracking satellites, a separate but fitting reminder of how intertwined the Musk ecosystem has become with the realities of modern conflict.

NASA sends humans to the Moon for the first time since 1972 – Here’s what’s next
NASA’s Artemis II launched four astronauts toward the Moon on the first crewed lunar mission since 1972.

NASA launched four astronauts toward the Moon on April 1, 2026, marking the first crewed lunar mission since Apollo 17 in December 1972. The Artemis II mission lifted off from Kennedy Space Center aboard the Space Launch System rocket at 6:35 p.m. EDT, sending commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch, and Canadian astronaut Jeremy Hansen on a 10-day journey around the far side of the Moon and back.
The mission does not include a lunar landing. It is a test flight designed to validate the Orion spacecraft’s life support systems, navigation, and communications in deep space with a crew aboard for the first time. If the crew reaches the planned distance of 252,000 miles from Earth, they will set a new record for the farthest any human has ever traveled, surpassing even the Apollo 13 distance record.
As Teslarati reported, SpaceX holds a central role in what comes next. The Starship Human Landing System is under contract to carry astronauts to the lunar surface for Artemis IV, now targeting 2028, after NASA restructured its mission sequence due to delays in Starship’s orbital refueling demonstration. Before any Moon landing happens, SpaceX must prove it can transfer propellant between two Starships in orbit, something no rocket program has done at this scale.
The last time humans left Earth’s orbit was 53 years ago. Gene Cernan and Harrison Schmitt of Apollo 17 were the final people to walk on the Moon, a record that stands to this day. Elon Musk has long argued that returning is not optional. “It’s been now almost half a century since humans were last on the Moon,” Musk said. “That’s too long, we need to get back there and have a permanent base on the Moon.”
The Artemis program involves 60 countries signed onto the Artemis Accords, and this mission sets several firsts beyond distance. Glover becomes the first person of color to travel beyond low Earth orbit, Koch the first woman, and Hansen the first non-American astronaut to reach the Moon’s vicinity. According to NASA’s live mission updates, the spacecraft’s solar arrays deployed successfully after liftoff and the crew completed a proximity operations demonstration within the first hours of flight.
Artemis II is step one. The Moon landing and the permanent lunar base come later. But after more than five decades, humans are heading back.

Tesla Optimus Gen 3 is coming to the Tesla Diner with new ambitions
Tesla’s Optimus robot left the Hollywood Diner within months of opening. Now Musk is planning its return with a bigger role and a major Gen 3 upgrade underway.
Tesla’s Optimus robot was one of the most talked-about features when the Tesla Diner opened on Santa Monica Boulevard in Hollywood on July 21, 2025. Dubbed “Poptimus” by Tesla fans, the Gen 2 robot stood upstairs at the retro-futuristic, drive-in theater and Tesla Supercharging station, scooping popcorn into bags and handing them to guests with a wave.
The diner itself had been years in the making. Elon Musk first floated the idea in 2018 with a tweet about building an “old-school drive-in, roller skates & rock restaurant” at a Hollywood Supercharger. What eventually opened was a unique two-story neon-lit space, with 80 EV charging stalls, and Optimus serving as a live demonstration of where Tesla’s ambitions were headed.
If our retro-futuristic diner turns out well, which I think it will, @Tesla will establish these in major cities around the world, as well as at Supercharger sites on long distance routes.

But Optimus did not stay long, and was gone by December 2025.
Now, the robot is set to return with a more demanding job. Musk has ambitions for Optimus to take on a food runner role in 2026, delivering meals directly to cars at the Supercharger stalls. While the latest Gen 3 Optimus is likely to initially take on its previous popcorn-serving role, it wouldn’t be out of the question for Optimus to see a quick promotion. With improved hand dexterity that features 50 total actuators and 22 degrees of freedom per hand, and significantly more powerful processing through Tesla’s latest AI5 chip that includes Grok-powered voice interaction, Musk described Optimus at the Abundance Summit on March 12, 2026, as “by far the most advanced robot in the world, Nothing’s even close.”

That confidence is backed by a major manufacturing shift. At the Q4 2025 earnings call in January, Musk announced Tesla would discontinue the Model S and Model X and convert those Fremont production lines to build Optimus. “It’s time to basically bring the Model S and X programs to an end,” he said, calling for a pivot that reflects where the Tesla’s future lies.
