The Elon Musk and Herbert Diess budding bromance seems to be going strong, with the Tesla CEO making a surprise appearance at the Volkswagen managers’ 2021 Leadership Summit in Alpbach, Austria.
Elon Musk’s attendance at the VW Group gathering reveals Diess and the Tesla CEO’s deep respect for each other. Musk’s appearance also shows that Diess is willing to change his mindset, something that he believes everyone at Volkswagen AG needs to go through to compete with new automakers.
“We need a new mindset at Volkswagen AG to take on the new competition!” posted Herbert Diess on LinkedIn. “After three days with 200 top managers from the world, I am confident: We have everything we need to tackle the challenges. Right strategy, right competencies, right management team. We can do it—but we have to deliver now.”
It seems like Diess invited Elon Musk to speak at the summit to learn from Tesla’s CEO and gain some perspective. According to Handelsblatt, Diess asked Musk why Tesla was so nimble compared to its rivals.
The Tesla CEO replied that it came down to his management style and how he thought of himself. Musk shared that he perceived himself as an engineer, first and foremost, one that has an eye for supply chains, logistics, and production.
Musk may have given Diess and VW managers some encouraging words at the meeting as well, assuring everyone that they were moving in the right direction.
“As a surprise guest [Elon Musk] joined us for a video talk in the evening. Happy to hear that even our strongest competitor thinks that we will succeed in the transition if we drive the transformation with full power,” Diess noted.

VW’s Electric Future
In a LinkedIn post, Diess mentioned VW Group’s headquarters in Wolfsburg and Project Trinity. The Wolfsburg plant has long been one of VW’s key facilities. Project Trinity is VW’s upcoming electric sedan project, and it will be built in the Wolfsburg plant. The company aims to start Project Trinity production at Wolfsburg by 2026.
According to VW CEO Ralf Ralf Brandstätter, Project Trinity is like the point of “crystallization” for the legacy OEM’s ACCELERATE strategy. VW Group plans to “accelerate” its transformation into a software-driven mobility provider, and Project Trinity seems to be an integral part of the company’s evolution.
VW and Tesla’s Healthy Competition
Diess noted that Project Trinity could revolutionize the company. He observed that Trinity could help Volkswagen compete with Tesla Giga Berlin in Grünheide, highlighting that Tesla Giga Berlin “will build cars with an impressive speed and productivity.”
At Giga Fest, a poster stated that Giga Berlin aims to produce one car body every 45 seconds, hinting at how many cars Giga Berlin could make in the future. The sign did not indicate whether the goal was short-term or long-term.
However, it has been reiterated repeatedly that one of Tesla’s early goals for Giga Berlin is to produce 500,000 vehicles a year. Since Giga Berlin’s goal has been made public, Volkswagen Group has a clear EV production goal to compete with Tesla in Grünheide.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.

Tesla expands ridesharing service in California to new hotspot
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.
Our Bay Area rideshare service now goes to SFO ✈️
— Tesla AI (@Tesla_AI) July 21, 2026
Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
