Opinion: Where would Herbert Diess fit best (hypothetically)?
Herbert Diess is officially no longer a Volkswagen employee, effective Wednesday. The seven-year reign as CEO and Chairman of the Board of Management came to somewhat of an abrupt end after Diess and VW decided to part ways at the end of August.
“These were the most rewarding seven years of my career. The future of our industry can be brilliant, but we have to change fast. Volkswagen has already changed tremendously and is well underway,” Diess said. “We have transformed the company that was seen as an autocratic cheat into a global thought leader in clean mobility.”

Diess’s future remains in question, and while retirement is the likely option, there are several routes that he could potentially go, barring any stipulation in his contract that would eliminate the possibility of working for a competitor. While it is a long shot, Diess has three main automakers he would likely benefit from almost immediately, making an impact on several companies as his proven track record speaks for itself.

While I have already been in numerous discussions with various people about this possibility, and even though it seems unlikely, the first company that Diess would benefit is Tesla. Not only does Diess share a friendship with Elon Musk, but he could also benefit Tesla’s European business with additional expertise on the market. VW has performed very well in Europe in terms of EVs, and helping Tesla expand its operations throughout the continent would likely be a huge advantage for the company.
Tesla undoubtedly has a bright future in Europe, but Volkswagen currently holds the EV title there. The AG owned 1/4 of the European plug-in market in 2021, according to CleanTechnica data.
Toyota
I believe Diess has the track record to be a considerable ally to Toyota. Why? Toyota and VW have a lot of parallels, and Diess would likely navigate through them with considerable success.
Toyota is the world’s largest automotive manufacturer by volume, and it has been for some time. The last time a major automotive manufacturer outproduced Toyota was when GM built nearly 1M cars more than the Japanese company in 2011. Even VW finished ahead of Toyota in terms of production that year, but it has been a masterclass in production ever since.

Volume is not the only way the two companies are somewhat similar. EV development is also somewhat of a parallel. VW has coming out of the Dieselgate crisis and had to make major waves to regain consumer trust. Diess knew this, and pushed incredibly hard for several years to help VW reinvent its reputation as a sustainable company. Toyota really needs the same thing.
Although it isn’t going thru an emissions scandal, Toyota has basically half-committed to EVs, aiming to go toward hydrogen and hybrid vehicles instead. It is not to say that the company hasn’t contributed to sustainability in other ways: the Toyota Prius was a huge step forward in sustainable transport. Evolution needs to continue, however, and it is time for Toyota to really begin developing some high-tech EVs. They’re falling behind, and Diess, with his experience in high-volume companies and sluggish EV plans, is a good fit.
General Motors
GM would also be a good fit for Diess simply because of his push and determination to transition a company quickly. GM is honestly a company that has so much potential, but it feels like they’re falling just short of the mark in so many areas. The Bolt has plagued GM with bad advertising for several years, the HUMMER EV is having more issues than what were anticipated, and the company’s plans for electrification seem to be one drastic announcement followed by silence and promises that they’ll one day overtake Tesla.
While Tesla dominates the industry now, it will eventually take a few decades for others to catch up, and they likely will. However, Tesla is establishing itself as the leader and it is no secret. It is going to take a long time to figure out the tech and the manufacturing and the supply chain.

GM will likely catch up to Tesla, but it won’t be in the 2020s or 2030s. They’ll all even out, just as the market is now. A lot of car companies do a lot of business, and it’s only a matter of time before other companies begin to figure things out.
GM will absolutely be a true player in the EV industry, and it’s just going to take some time. This is where I feel Diess would be a considerable asset to GM, simply because he emphasized on accelerating VW’s transition to sustainable energy. The goals of 2035 or more were simply not going to work. Things needed to be figured out now, and the goal is to establish yourself as an early player in the disruption of a sector. VW has done that thanks to Diess, GM has announced more (at least to me) but accomplished considerably less.

Tesla Model Y L gets new entertainment feature
Beyond audio quality, Immersive Sound X aligns with Tesla’s ecosystem of over-the-air updates, potentially allowing future refinements.
Tesla is including a new entertainment feature in the Model Y L, improving the vehicle even further and making it what appears to be the best configuration of the all-electric crossover globally.
Unfortunately, we in the U.S. do not yet have access to the vehicle, and the plans for it to enter the market remain up in the air, as CEO Elon Musk has said it could appear late this year. However, there is nothing concrete at this time.
Tesla’s latest enhancement to the Model Y L is a new Immersive Sound X feature, exclusive to the Model Y L.

— Electric Future (@electricfuture5) March 16, 2026
It aims to transform the in-car listening experience into something truly cinematic. First introduced by Tesla China in October 2025, this advanced audio mode is now rolling out to deliveries in Australia and New Zealand, highlighting Tesla’s approach to region-specific premium upgrades.
At its core, Immersive Sound X leverages real-time sound extraction technology to create a customizable 3D soundstage. Using advanced algorithms, it analyzes audio tracks to separate direct sounds, such as vocals or lead instruments, from ambient elements like echoes and reverb.
The system then positions direct sounds front and center while diffusing ambient sounds to the side and rear speakers, simulating an expansive virtual environment. This results in a heightened sense of depth and spatial awareness, making listeners feel as if they’re in a concert hall or studio.
What sets Immersive Sound X apart from the standard Immersive Sound found in other Tesla models is its hardware dependency and enhanced processing. The Model Y L boasts an 18-speaker system with a subwoofer, compared to the 15-speaker setup, plus a subwoofer, in the Model Y Long Range’s previous premium audio configuration.
This upgrade provides more “kick” and precision, enabling finer control over the soundstage. Unlike traditional surround sound, which requires multi-channel mixes like Dolby Atmos, Immersive Sound X works with any stereo source from platforms like Spotify or Apple Music, so every owner will be able to use it.
Tesla Model Y lineup expansion signals an uncomfortable reality for consumers
You can fine-tune the experience via an adjustable immersion slider, scaling the “size” of the virtual space to personal preferences. This caters to a more custom sound.
An Auto mode intelligently adapts based on media type, whether it’s music, podcasts, or videos, ensuring optimal immersion without manual tweaks. This feature is unavailable on standard Model Y variants (with 7 or 15 speakers) or Model 3 trims, underscoring Tesla’s strategy to differentiate higher trims through superior hardware and software integration.
Beyond audio quality, Immersive Sound X aligns with Tesla’s ecosystem of over-the-air updates, potentially allowing future refinements.
For audiophiles and casual listeners alike, it elevates mundane commutes into immersive journeys, proving Tesla’s commitment to blending cutting-edge tech with user-centric design.

Elon Musk teases crazy outlook for xAI against its competitors
Musk’s response was vintage hyperbole, designed to rally supporters and dismiss doubters, something his responses on social media often do.
Elon Musk has never been one to shy away from crazy timelines, massive expectations, and outrageous outlooks. However, his recent plans for xAI and where he believes it will end up compared to its competitors are sure to stimulate conversation.
In a bold and characteristic response on X, Elon Musk fired back at a recent analysis that positioned his AI venture, xAI, as lagging behind industry frontrunners.
The post, from March 14, came as a direct reply to forecaster Peter Wildeford’s assessment, which drew from benchmarks and reporting to rank AI developers.
xAI will catch up this year and then exceed them all by such a long distance in 3 years that you will need the James Webb telescope to see who is in second place
— Elon Musk (@elonmusk) March 14, 2026
Wildeford placed Anthropic, Google, and OpenAI in a virtual tie at the top, with xAI and Meta trailing by about seven months. Chinese players like Moonshot, Deepseek, zAI, and Alibaba were estimated to be nine months behind, while France’s Mistral lagged by about a year and a half.
Musk’s response was vintage hyperbole, designed to rally supporters and dismiss doubters, something his responses on social media often do.
He claimed xAI would “catch up this year,” meaning by the end of 2026, erasing that seven-month deficit against the leaders. But he didn’t stop there.
Musk escalated his vision to 2029, predicting xAI would “exceed them all by such a long distance” that observers would need the James Webb Space Telescope, NASA’s orbiting observatory stationed about 930,000 miles from Earth, to spot whoever lands in second place. This analogy underscores Musk’s confidence in xAI’s trajectory, implying an astronomical lead that could redefine the AI landscape.
Breaking down these claims reveals Musk’s strategic optimism. First, the short-term catch-up: xAI, launched in 2023, has already released models like Grok, but recent benchmarks, including those for Grok 4.2, have shown it falling short in capabilities compared to rivals.
Anthropic’s Claude series, Google’s Gemini, and OpenAI’s GPT models dominate in areas like reasoning, coding, and multimodal tasks. Musk’s assertion suggests aggressive scaling in compute, talent, or architecture, perhaps leveraging xAI’s ties to Tesla’s Dojo supercomputers or Musk’s vast resources, to close the gap swiftly.
The longer-term dominance by 2029 paints an even more audacious picture. Musk envisions xAI not just parity but supremacy, outpacing competitors in innovation speed and model sophistication.
This could involve breakthroughs in energy-efficient training, real-world integration, like Tesla’s robotics, or ethical AI alignment, aligning with Musk’s stated goal of “understanding the universe.”
Critics, however, point to parallels with Tesla’s Full Self-Driving delays; one reply highlighted Musk’s 2023 promise of FSD readiness. Musk has made this promise for many years, and although the system has been strong and improving, it is still a ways off from the completely autonomous operation that was expected by now.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
Musk’s comment highlights the intensifying U.S.-centric AI race, with xAI challenging the “three-way” dominance noted by Wharton professor Ethan Mollick, whom Wildeford quoted. As geopolitical tensions rise—evident in the Chinese firms’ lag—Musk’s tease could spur investment and talent wars.
Yet, it also invites scrutiny: Will xAI deliver, or is this another telescope-needed mirage? In an industry where timelines slip but stakes soar, Musk’s words keep the spotlight on xAI’s ambitious path forward.

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.
