Tesla, other EVs required to have ‘traditional engine’ sound to meet new EU rule
Electric vehicles such as Teslas are known for being incredibly quiet. Without an internal combustion engine’s controlled explosions under the hood, electric cars are capable of operating in near-total silence. This, according to a new EU rule, will be changed soon.
A new EU rule coming into force on Monday requires new electric vehicles to be equipped with a pedestrian noisemaker. The new regulations follows concerns that low-emission vehicles such as battery-electric cars are simply too quiet for the road, making them a risk for pedestrians, cyclists, and visually-impaired individuals (among others). According to the new ruling, a car’s Acoustic Vehicle Alert System (AVAS) must be engaged when reversing or traveling below 12 mph (19 km/h).
In its ruling, the EU noted that vehicles usually back up or travel at low speeds in areas that are near people, such as city streets or crosswalks, though the new regulations does allow drivers to deactivate their vehicles’ pedestrian noisemakers as necessary. By 2021, the EU noted that all electric vehicles — not just new models coming to the market — must be equipped with an AVAS.
Quite interestingly, the ruling mentioned that the noise-emitting devices would give EVs a sound that is similar to a “traditional engine,” according to a BBC report. This particular detail is notable, since making electric vehicles sound identical to conventional cars will likely result in some levels of noise pollution, something that EVs completely avoid.
Road noises, after all, are considered the second most harmful environmental stressor in Europe, surpassed only by air pollution. The European Federation for Transport and Environment (also known as Transport and Environment or T&E), for one, notes that vehicle noises are a “major cause, not only of hearing loss, but also of heart disease, learning problems in children and sleep disturbance.”
On the flip side, pedestrian noisemakers do make it far easier for the visually impaired to detect where vehicles are on the road. This was highlighted by Guide Dogs for the Blind, a charity that has complained about the absence of sounds from low-emission vehicles. Guide Dogs welcomed the new EU ruling, though the group noted that it would be better if EVs are required to produce sounds at all speeds.
The UK’s Minister of State at the Department for Transport, Michael Ellis, noted in a statement to the publication that the ruling came about as a result of the government wanting the “benefits of green transport to be felt by everyone,” while considering the safety needs of people at the same time. “This new requirement will give pedestrians added confidence when crossing the road,” he said.
While the consideration for the visually-impaired is quite admirable in the new ruling, it is quite interesting to see the EU regulations require electric vehicles to sound like traditional gas cars. EVs, after all, could have their own unique sound, as could be seen in the Jaguar I-PACE, the Audi e-tron, and even the prototype units of the Porsche Taycan. Even Tesla seems to be working on an AVAS, as hinted at by what appears to be a speaker grille on a Model 3’s underbody. Nevertheless, when Tesla rolls out its vehicles’ pedestrian noisemakers, one could be assured that it would be designed to minimize noise pollution, and it would most likely not simulate the sounds of a “traditional” engine.

Tesla seen as early winner as Canada reopens door to China-made EVs
Tesla had already prepared for Chinese exports to Canada in 2023 by equipping its Shanghai Gigafactory to produce a Canada-specific version of the Model Y.
Tesla seems poised to be an early beneficiary of Canada’s decision to reopen imports of Chinese-made electric vehicles, following the removal of a 100% tariff that halted shipments last year.
Thanks to Giga Shanghai’s capability to produce Canadian-spec vehicles, it might only be a matter of time before Tesla is able to export vehicles to Canada from China once more.
Under the new U.S.–Canada trade agreement, Canada will allow up to 49,000 vehicles per year to be imported from China at a 6.1% tariff, with the quota potentially rising to 70,000 units within five years, according to Prime Minister Mark Carney.
Half of the initial quota is reserved for vehicles priced under CAD 35,000, a threshold above current Tesla models, though the electric vehicle maker could still benefit from the rule change, as noted in a Reuters report.
Tesla had already prepared for Chinese exports to Canada in 2023 by equipping its Shanghai Gigafactory to produce a Canada-specific version of the Model Y. That year, Tesla began shipping vehicles from Shanghai to Canada, contributing to a sharp 460% year-over-year increase in China-built vehicle imports through Vancouver.
When Ottawa imposed a 100% tariff in 2024, however, Tesla halted those shipments and shifted Canadian supply to its U.S. and Berlin factories. With tariffs now reduced, Tesla could quickly resume China-to-Canada exports.
Beyond manufacturing flexibility, Tesla could also benefit from its established retail presence in Canada. The automaker operates 39 stores across Canada, while Chinese brands like BYD and Nio have yet to enter the Canadian market directly. Tesla’s relatively small lineup, which is comprised of four core models plus the Cybertruck, allows it to move faster on marketing and logistics than competitors with broader portfolios.

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.
