Mercedes-Benz apologizes for ‘red hot’ AMG GLA 45 ad amid Europe’s summer heat wave
Veteran automaker Mercedes-Benz has issued an apology on Twitter following a gaffe in a recent ad for one of its vehicles, the Mercedes-AMG GLA 45 4MATIC. The apology comes amidst a strong negative reaction from users of the social media platform, many of whom found the company’s framing of the vehicle as a “red hot” addition to this summer’s record-setting temperatures as insensitive.
Mercedes-Benz’s advertisement for the vehicle featured a variant of the GLA 45 4MATIC in a stunning red finish. As a way to emphasize the car’s attributes, the automaker related its shade to the sweltering summer heat. “If this summer wasn’t warm enough already, the Mercedes-AMG GLA 45 4MATIC will heat things up even more with this red-hot finish,” the carmaker wrote.
The wordplay was not appreciated by a notable number of social media users, many of whom called out the company for the seemingly tone-deaf nature of the tweet. This year’s summer has been particularly brutal, after all, with Europe’s scorching heat wave in July being 3 degrees Celsius hotter than usual. Scientists have noted that the intense heat experienced in the region was exacerbated by climate change, as noted in a CNN report.
So notable were the effects of July’s summer heat wave in Europe that last Wednesday, a Eurostar train traveling from Belgium to London broke down and trapped 40 passengers in 40 degrees Celsius heat without air conditioning. In France, public events and schools were canceled as temperatures reached alarming levels. In Spain, the heat helped exacerbate a 10,000-acre wildfire, which was one of the worst to hit Catalonia in decades.
July’s heat wave was felt across the European region, with the UK, Belgium, and the Netherlands recording their highest temperatures to date last month. Germany, where Mercedes-Benz is based, experienced the same intense heat, with temperatures topping 40 degrees. According to a report from the World Weather Attribution group, temperatures in the region would have been between 1.5-3 degrees lower without climate change.
Amidst the strong reaction to its advertisement, Mercedes-Benz has posted an apology, admitting that the tweet was not its “finest hour.” “Folks, that was really not our finest hour. We apologize sincerely. We’re working hard on the transformation of our car fleet. We aim for CO2-neutral mobility,” the company wrote. The automaker also included a link to its Ambition2039 initiative, a plan for the company to become carbon-neutral in 20 years.
Daimler, Mercedes-Benz’s parent company, is currently in hot water in Germany, with the company being on the sights of the country’s vehicle authority, the Federal Motor Transport Authority (KBA) over the alleged use of illegal shut-off devices for the diesel-powered Mercedes-Benz GLK 220, a popular SUV, as well as other vehicles equipped with the automaker’s OM642 and OM651 engines. The KBA’s investigation of Daimler has resulted in a recall of 60,000 units of the GLK, though the number could be as high as 700,000 vehicles if other vehicles using the OM642 and OM651 engines are also found to have used the emissions-cheating device.

Tesla confirms that work on Dojo 3 has officially resumed
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo 3,” Elon Musk wrote in a post on X.
Tesla has restarted work on its Dojo 3 initiative, its in-house AI training supercomputer, now that its AI5 chip design has reached a stable stage.
Tesla CEO Elon Musk confirmed the update in a recent post on X.
Tesla’s Dojo 3 initiative restarted
In a post on X, Musk said that with the AI5 chip design now “in good shape,” Tesla will resume work on Dojo 3. He added that Tesla is hiring engineers interested in working on what he expects will become the highest-volume AI chips in the world.
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3. If you’re interested in working on what will be the highest volume chips in the world, send a note to AI_Chips@Tesla.com with 3 bullet points on the toughest technical problems you’ve solved,” Musk wrote in his post on X.
Musk’s comment followed a series of recent posts outlining Tesla’s broader AI chip roadmap. In another update, he stated that Tesla’s AI4 chip alone would achieve self-driving safety levels well above human drivers, AI5 would make vehicles “almost perfect” while significantly enhancing Optimus, and AI6 would be focused on Optimus and data center applications.
Musk then highlighted that AI7/Dojo 3 will be designed to support space-based AI compute.
Tesla’s AI roadmap
Musk’s latest comments helped resolve some confusion that emerged last year about Project Dojo’s future. At the time, Musk stated on X that Tesla was stepping back from Dojo because it did not make sense to split resources across multiple AI chip architectures.
He suggested that clustering large numbers of Tesla AI5 and AI6 chips for training could effectively serve the same purpose as a dedicated Dojo successor. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk wrote at the time.
Musk later reinforced that idea by responding positively to an X post stating that Tesla’s AI6 chip would effectively be the new Dojo. Considering his recent updates on X, however, it appears that Tesla will be using AI7, not AI6, as its dedicated Dojo successor. The CEO did state that Tesla’s AI7, AI8, and AI9 chips will be developed in short, nine-month cycles, so Dojo’s deployment might actually be sooner than expected.

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.

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.
