The Tesla Model S recently dominated an extreme cold-weather testing study performed by Norweigan outlet Motor, accumulating 530 kilometers (329.327 miles) in some of the harshest Winter conditions available.
Of the twenty-nine electric vehicles tested during the assessment, the Model S was the only vehicle to achieve at least 450 kilometers of real-world driving range in frigid temperatures and snowy terrain.

The study utilized a variety of EVs from several different manufacturers. Tesla Model S “Standard,” Model X Plaid, and Model Y Rear-Wheel-Drive vehicles participated in the study, with Mercedes EQE 300, BMW i7, Volkswagen’s ID.5 and ID.BUZZ also taking part.
The publication broke down how it tests vehicles to maintain a fair and equal opportunity for desirable results. The test is performed every six months, winter and summer, following the same route:
“A loop through Oslo, up Rv4 to Gjøvik, from there E6 up to Hjerkinn, then east and around Rondane over Venabygdsfjellet, down to Ringebu and up E6 again.”

The cars are driven at the speed limit until their charge is depleted, and no driver support systems, such as cruise control, are permitted during the test.
Impressive in its own right, the Model S achieved a massive 530 kilometers of range on a single charge. Despite only being charged 98 percent “due to a technical problem,” the Model S Dual Motor All-Wheel Drive didn’t have a very close competitor. In fact, the vehicle that came closest was the Tesla Model X Plaid, which achieved 444 kilometers (275.889 miles). Right behind it were the BMW i4 and NINE ET7, which both achieved 434 kilometers before depleting their travel distance.
The Model S also had one of the lowest deviations from its WLTP range ratings, coming in at 16.40 percent. Of the top ten performing vehicles, the Model S had the lowest, with the Model X coming in second with 18.23 percent.
| Model | WLTP range | Achieved range | Percentage deviation, range |
| Tesla Model S Standard | 634 | 530 | -16.40% |
| Mercedes EQE 300 | 614 | 409 | -33.39% |
| BMW i7 xDrive60 | 595 | 424 | -28.74% |
| NINE ET7 | 580 | 434 | -25.17% |
| BMW i4 eDrive40 | 565 | 434 | -23.19% |
| Tesla Model X Plaid | 543 | 444 | -18.23% |
| Nissan Ariya 2WD | 533 | 400 | -24.95% |
| Volkswagen ID.5 Pro | 526 | 378 | -28.14% |
| Bid Han | 521 | 406 | -22.07% |
| Hongqi E-HS9 prototype 120 kWt | 515 | 389 | -24.47% |
Tesla has battled range loss in colder climates with a variety of techniques, including the most notable, which is the heat pump.
After including the heat pump on the Model Y, Tesla eventually implemented it on its three other vehicles, with the Model S and Model X receiving the addition with its Refreshed cars in 2021.
Elon Musk once said the heat pump was “some of the best engineering I’ve seen in a while.” It was developed by Joseph Mardall and other members of the Tesla engineering team. Mardall left Tesla in early 2021 to join Zipline, a robotics and autonomy-focused logistics company.
Another fun fact: the Model S beat the record set by the 2021 Tesla Model 3 Dual Motor Long Range, which made it 521 kilometers (323.734 miles).

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.
