This Tesla safety engineer just left after over 14 years
The crash engineer didn’t disclose any specific reasons for his departure. “I have decided now is the time to move on.”
A key Tesla safety engineer has departed from the company, as shared earlier this month, following nearly a decade and a half spent working across three of the automaker’s locations.
In a post on LinkedIn last week, Tesla’s Principal CAE Crash Safety Engineer, Petter Winberg, announced his departure from the company after working there for over 14 years. Winberg played a major role in Tesla’s efforts to make its vehicles some of the safest out there, starting as a Senior Tech Specialist in 2011 and slowly getting promoted to his current position.
In his position, Winberg worked on crash architectures for the Cybercab, Semi, and future vehicles, along with the Model S, Model X, Model 3, and Model Y, and developing specific accident architectures once Giga Casting production came into play. The executive’s full departure announcement reads as follows:
Elon, 2011: “I want Tesla vehicles to be the safest on the planet” Me: “Challenge accepted”
Having developed Model S, S-DM, X, 3, Y, Y-SP as well as future crash architectures, I have decided now is the time to move on. Thank you Tesla, keep crushing it! What an incredible team, I will miss you all.

During his time at Tesla, the engineer worked at the company’s engineering headquarters in Palo Alto, California, before moving to the company’s nearby Fremont factory, then finally landing at the automaker’s Gothenburg, Sweden facilities, where he has served in his current position since January 2020. Prior to this, Winberg also worked at Volvo, Saab, Ford, and Volvo.
The post also elicited a handful of comments from colleagues, including one commenter who called Winberg the “master of crash simulations,” and multiple others who praised him for his guidance and knowledge of the subject.
Tesla has also been heavily focused on making its vehicles safe since the early days, as Winberg points out.
As one example in October, Tesla VP of Vehicle Engineering Lars Moravy reiterated this point by highlighting both the company’s active and passive safety features included in the Model Y and other vehicles. Moravy detailed that, while features built-in for the Autopilot and Supervised Full Self-Driving (FSD) systems provide active safety features meant to help prevent crashes, even if “the worst occurs, [Tesla drivers] will be protected by the best passive safety cars on the planet.”
The company’s vehicles have also earned top safety ratings across four different continents at this point, most recently including a five-star safety rating for the Cybertruck from the top auto regulator in the U.S.
Over the last several months, Tesla has also faced executive and high-profile engineering departures a handful of times, as can probably be expected from most companies of its size.
Some examples include the departure of Safety Policy Lead Marc Van Impe and Chief Information Officer Nagesh Saldi in October, VP of Finance and Business Operations Sreela Venkataratnam in August, and both SVP of Powertrain and Energy Engineering Drew Baglino and VP of Public Policy and Business Development Rohan Patel in April, to name just a few.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.
