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 Cybercab and Robotaxi’s real advantage won’t be the ride service
For a century, the car has asked the same thing of its owner, which is basically to pay attention. Even the best ride-hailing app like Uber or Lyft only moved the problem into someone else’s hands. You stopped driving, but you still sat in a stranger’s car, while half listening, and wondering whether to take a phone call in the car without being rude. The Cybercab has no wheel, no pedals and no driver. With Grok @bot now live inside it, it becomes something else entirely, and I think that matters more than the fleet count that everyone is tracking.
Grok @bot is an agent, not a voice assistant. A rider signs in once, and from then on can say what they need and watch it happen. Order dinner from a favorite restaurant. Fill the grocery cart. Move money, answer email, adjust a calendar, push a work project forward. Tesla engineer Yun-Ta Tsai confirmed it is enabled across every Cybercab and the rest of the Model Y fleet, and Tesla’s own pitch is that Full Self-Driving handles the commute while Grok handles the errands.
Think about what that does to a thirty minute ride. Uber sells you a trip, while Waymo sells you the same trip in a more private setting. Tesla is selling the thirty minutes themselves, returned to you with an assistant attached. Errands that used to eat a Saturday get done between pickup and drop off. The ride stops being dead time between two places and becomes a place of its own.
Tesla integrates Grok Bot into its vehicles for the ultimate personal assistant
Best of all, your Bots follow you into any Cybercab, and presumably your own Tesla, then logs you out automatically when you step out. Anyone can bolt a chatbot onto a screen, but much harder to own the vehicle, the autonomy stack and the assistant at once. It also quietly ties SpaceX’s Super Intelligence business to Tesla’s fleet, after Tesla converted its xAI stake into SpaceX equity. The relationship between those two companies is getting harder to describe as separate.
This is also where the hard questions start, because an agent that can spend your money in a vehicle other people also ride in needs some answers. How does it handle a voice it shouldn’t trust? What gets recorded, who can see it, and for how long? What happens when a rider leaves halfway through a task?
If Tesla gets those answers right, the scoreboard changes. We have been counting Cybercabs and wait times. The more telling number may be what riders accomplish per trip. That is data almost no one else will ever have, and it is the real reason to watch Grok @bot.

Tesla’s mirrorless Cybercab will give riders a visibility upgrade
Tesla engineer confirms Cybercab update letting riders pull up rear and repeater cameras on demand.
Tesla is working on a Cybercab update that would let passengers pull up the vehicle’s rear and side cameras on demand, and the request came straight from a rider.
The exchange played out on X late Friday. Cybercab rider Dan Burkland shared photos of the two-seater’s cabin screen after an evening ride, praised the UI team’s work, and left one request: let riders open the rear and repeater cameras whenever they want, “especially for peace of mind.” Tesla UI software engineer Evan (@CarCoder) answered with two words: “In development.”
The Tesla UI team absolutely crushed it with the infotainment software. Nicely done @CarCoder!
One feature request: Allow folks to pull up the rear & repeater cameras on demand. This would be great especially for peace of mind. https://t.co/mNAOSLx6pE

The idea fits a pattern Teslarati has tracked since public rides began. Days after paid Cybercab service opened in Austin, Tesla sent riders a survey that asked them to rate the touchscreen, the app and the cabin, and to pick the features they wanted most. We reported on that survey in September, and a camera view is the kind of small software change Tesla can push quickly if riders keep asking.
It also speaks to something unique about the vehicle. With no steering wheel, no pedals and no driver, passengers have no mirror to check and no way to see behind them. The hardware is clearly built for camera awareness, from the repeater cameras to the rear camera. Letting a passenger look through those same cameras would give a nervous first time rider a way to confirm what is around the car.
The timing matters because the fleet is growing fast. Tesla’s Robotaxi account said on Saturday that more than 300 Cybercabs are now serving Austin, an eightfold increase in 30 days, and Tesla AI chief Ashok Elluswamy named Dallas as the next city. More cars and more cities mean more people riding in a driverless vehicle for the first time, which is exactly when small trust features carry weight.
For now, the feature is confirmed only as in development. If Tesla follows its usual pattern with Cybercab software, riders could see it appear in a point release without any announcement, and Teslarati will watch for it.

Elon Musk’s surprise addition to the X Takeover lineup has fans talking
Elon Musk will join Saturday’s X Takeover at Giga Texas for a live virtual interview.
Elon Musk will join X Takeover at Giga Texas on Saturday for a live virtual interview, according to Sawyer Merritt, who shared the news late Thursday. Musk will not be on stage in Austin. The conversation is set to stream for free on the @teslaownersSV account on X.
Organizers had kept expectations in check. In a September update, Tesla Owners Silicon Valley said Musk had appeared at the event twice before but was not promising a third appearance, even as fans hoped he would walk the Giga Texas grounds in person. A virtual spot matches 2024, when Musk gave a surprise interview of about an hour to the crowd in San Luis Obispo, as Teslarati reported at the time.
Wasn’t expecting this 🫡

This year’s edition is a first in several ways. It is the first X Takeover held outside California and the first at a Tesla facility, with tickets selling out in eight days. Tesla provides the venue, but the event is produced independently by Tesla Owners Silicon Valley. The main event runs from 10 a.m. to 6 p.m. CT, followed by a drone and light show at 9 p.m. Maye Musk is the keynote speaker, Franz von Holzhausen is set for a virtual keynote, and Nicki Minaj is the special guest. Joe Tegtmeyer, whose drone footage Teslarati used to track the Optimus factory steel frame at Giga Texas, is also on the speaker list.
Musk’s interview topics have not been revealed, but the backdrop is busy. Tesla doubled its Cybercab fleet in Austin in late September, and last week Musk explained why Robotaxi hours only moved from 10 p.m. to 11 p.m.. Merritt also reported Thursday that Texas DMV records now show 319 registered Cybercabs, up from 169. NHTSA’s deadline for Tesla’s sworn answers on Cybercab certification is October 30, and Tesla reports third quarter earnings on October 21.
Fans who cannot make it to Austin can watch the livestream on X. Musk tends to say more in unscripted settings than he does in prepared remarks, which is the reason this one is worth having open on Saturday.
