Volkswagen shares Elon Musk’s test drive of the VW ID.3: ‘It’s pretty good’
One of the more surprising elements in Elon Musk’s recent visit to Germany was his meeting with Volkswagen Group executive Herbert Diess, who hosted the Tesla CEO at the Braunschweig Airport. During their two-hour meeting, the two electric car advocates took a drive in the ID.3, Volkswagen’s first EV from its MEB platform. The news came as a pleasant surprise to the electric car community, many of whom were interested to see Elon Musk’s insights on the ID.3, a car that could rise alongside the Model 3 in the mainstream vehicle market.
Fortunately, a video of Elon Musk’s Volkswagen ID.3 test drive was recently shared by Herbert Diess in his LinkedIn profile. The short video, which was also posted by the Volkswagen Group’s official Twitter account, featured Musk and Diess engaging in friendly conversation while the former was test driving the ID.3. As it turned out, Musk seemed to be pretty optimistic about the vehicle, at one point stating that the ID.3’s steering was “pretty good” for a non-sporty electric car.
Quite amusingly, the recently-shared video included segments of Herbert Diess setting Musk’s expectations about the ID.3 by reminding the Tesla CEO that the hatchback was a mainstream car and “not a race machine.” Laughing in response, Musk lightly stated that he “just wanted to see what the acceleration is like.” Musk could later be seen seemingly flooring the ID.3 while jokingly asking Diess “What’s the worst that could happen?”
In the few segments of the test drive featured in the clip, it could be seen that Musk inquired about several aspects of the ID.3, such as its battery pack and its driver-assist features. Diess, for his part, stated that the ID.3 is equipped with German state-of-the-art lane-keeping and emergency assist systems. The clip ended with Elon Musk and Herbert Diess getting out of the ID.3, with the Tesla CEO seemingly looking over some details of the mainstream EV. The ID.4, an all-electric crossover, could be seen nearby as well.
Diess later commented in his post with some new details about Musk’s Volkswagen ID.3 test drive. According to the Volkswagen Group executive, Musk was a bit critical of the ID.3’s torque at higher speeds. Diess also told Musk that for a true sports car experience, the Tesla CEO should try out the Porsche Taycan, an all-electric high-performance EV that Musk has openly supported in the past.
“Thanks for the visit, Elon! Hope you like the video. It was great driving the ID.3 with you! You were just quite critical with the available torque at higher speed. I told you: ‘Yes, we are on the runway – but no need for takeoff – it’s not a sports car.’ For this, you should try our Porsche Taycan. Looking forward to our next meeting!” Diess wrote.
Elon Musk and Herbert Diess have openly supported each other’s endeavors in the past, with the Tesla CEO recently stating during an interview at Gigafactory Berlin that companies like Volkswagen are putting in a lot of real work to get EVs to the mainstream market. While responding to a rather critical report on the Volkswagen Group executive last year, Musk noted on Twitter that “Herbert Diess is doing more than any big carmaker to go electric. The good of the world should come first. For what it’s worth, he has my support.”
Diess, for his part, has also openly defended Musk. Last October alone, reporters suggested that while the Model 3 was successful, they still view Tesla as a “niche” carmaker capable of making low-volume cars but out of its league in the mass market segment. Diess promptly came to Tesla’s defense, stating that the American carmaker is not a “niche” company in any way. “Tesla is not niche. The Model 3 is a large-series model and they are one of the biggest manufacturers of electric-car batteries. We have a lot of respect for Tesla. It’s a competitor we take very seriously,” the Volkswagen Group executive said.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Tesla set to launch “Terafab Project: A vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla is making one of the boldest bets in its history. On March 14, Elon Musk posted on X that the “Terafab Project launches in 7 days,” pointing to March 21, 2026 as the start date for what he has described as a vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla first confirmed Terafab on its January 28, 2026 earnings call, where Musk told investors the company needs to build a chip fabrication facility to avoid a supply constraint projected to materialize within three to four years. But the seeds were planted even earlier. At Tesla’s annual general meeting last year, Musk warned that even in the best-case scenario for chip production from their suppliers, it still wouldn’t be enough, and declared that building a “gigantic chip fab” simply had to be done.
While there has been no official announcement on where Tesla plans to break ground on the massive Terafab, all signs point to the North Campus of Giga Texas in Austin.
Months of speculation has surrounded Tesla’s North Campus expansion at Giga Texas, where drone footage captured by observer Joe Tegtmeyer revealed massive construction site preparation just north of the existing factory on a scale that rivals the original Giga Texas footprint itself.
Samsung’s Tesla AI5/AI6 chip factory to start key equipment tests in March: report
The project is projected to produce 100–200 billion AI and memory chips annually, targeting 100,000 wafer starts per month, at an estimated cost of $20 billion. Tesla is targeting 2-nanometre process technology and anticipated to be the most advanced node currently in commercial production. Dubbed the Tesla AI5 chip, the chip will pack 40x–50x more compute performance and 9x more memory than AI4, and will be among the first products Terafab factory is set to produce. This highly optimized, and massively powerful inference chip is designed to make full self-driving (FSD) and Tesla’s Optimus robots faster, safer, and with full autonomy.

This is where Terafab becomes a genuine game-changer. If Tesla successfully builds a 2nm chip fab at scale, it becomes one of only a handful of entities that’s capable of producing AI silicon in-house, with competitive implications that extend far beyond Tesla’s own vehicles, and potentially positioning Tesla as a chip supplier or licensor to other industries.

The next-gen Tesla AI chips will power advancements in Full Self-Driving software, the Cybercab Robotaxi program, and the Optimus humanoid robot line. Musk’s projections for Optimus require chip volumes that no existing external supplier can commit to on Tesla’s timeline.Competitors like Waymo and GM’s Cruise remain dependent on third-party silicon, leaving them exposed to the same supply chain vulnerabilities Tesla is now working to eliminate entirely.
The Terafab launch this week may not mean a factory opens its doors overnight, but it signals Tesla is serious about owning the entire AI stack, from software to silicon.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…
— Elon Musk (@elonmusk) March 11, 2026
Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.
— Elon Musk (@elonmusk) March 12, 2026
Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.
