US President Biden’s union-friendly $4,500 EV tax credit buff is facing a big challenge
The Biden administration’s proposed $4,500 EV tax credit buff for electric and electrified vehicles made in a union plant in the United States is meeting a big challenge. The union-friendly proposal is poised to undergo a review from the office of Elizabeth MacDonough, the Senate parliamentarian, who would then determine if the incentive qualifies under the US’ budget rules.
The $4,500 tax credit, which would be given to vehicles produced in the United States using union labor, stands to favor the Detroit Big Three heavily. Due to its overtly pro-union nature, the incentive has attracted a lot of criticism, particularly from automakers who are operating in the United States without union labor. These include Japanese carmakers Toyota and American EV maker Tesla.
Democratic Senator Joe Manchin, whose state of West Virginia hosts Toyota facilities, has expressed his disapproval of the proposed $4,500 tax credit addition for union-made EVs. In an interview with Automotive News last month, Manchin noted that the US government should not use tax dollars to pick winners and losers and that products made by companies should be able to speak for themselves.
“This is wrong. This can’t happen. It’s not who we are as a country. It’s not how we built this country, and the product should speak for itself. We shouldn’t use everyone’s tax dollars to pick winners and losers. If you’re a capitalist economy that we are in society, then you let the product speak for itself, and hopefully, we’ll get that, that’ll be corrected,” Manchin said.
If the Senate parliamentarian’s office concludes that the union-friendly $4,500 EV tax credit does not mesh with budget rules, Democrats may end up going back to the drawing board, or worse, remove the measure altogether, according to a Bloomberg report. Maryland Democratic Senator Ben Cardin, for his part, has noted that changes to the Biden administration’s proposed EV tax credit are already being discussed due to opposition from political figures such as Manchin.
“There have been some suggestions to alternatives by those that opposed it initially, and they are being looked at. It’s an evolving discussion,” Cardin said.
The Biden administration’s proposal would result in the current $7,500 EV tax credit being extended. An additional $500 would also be added to cars whose batteries were manufactured in the United States. These, together with a $4,500 additional credit if EVs were built in a union factory, could result in electric and electrified vehicle prices being lowered by as much as $12,500. Biden has also pushed for the buildout of an EV charging network across the United States.
Tesla CEO Elon Musk, however, noted during his interview at the Wall Street Journal’s CEO Council Summit that it would be better if the Biden administration’s proposals would not be passed. Musk even noted that he believes government support for the buildout of EV chargers is unnecessary.
“Unnecessary. I mean, do we need support for gas stations? So there’s no need for this support for a charging network. I’d delete it. I’m literally saying get rid of all subsidies. And also for oil and gas… Maybe (Tesla’s competitors) need it. I don’t know. But I think just generally, I’m in favor of deleting subsidies. When we started Tesla, there were no EV subsidies at all, and gasoline was super cheap. We did not anticipate any subsidies. That came later. The $7,500 tax credit came as a result not because of Tesla’s activity but because of General Motors’ lobbying. So I would just say delete them all,” Musk said.

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.
