The Tesla Model 3 and the Polestar 2 were recently pitted against each other by motoring outlet Top Gear. During the magazine’s review, the two vehicles were compared according to their efficiency, performance, and overall long trip capability, to name a new. As it turns out, it appears that the Polestar 2 is both the Model 3’s current biggest rival and strongest ally.
The Model 3 and the Polestar 2 are comparatively priced, with both vehicles commanding a price of about £600 per month in the UK. The two vehicles are also comparable when it comes to their batteries, with the Model 3 sporting a 75 kWh pack and the Polestar 2 being equipped with a 78 kWh unit. Consumption favors the Tesla during a 500-mile drive, however, as the Model 3 consumed 28.4 kW per 100 miles as opposed to the Polestar 2’s 35.7 kW per 100 miles. Part of this is due to the Polestar 2’s weight, which is about 595 lbs heavier than the Model 3.
That being said, when it comes to raw performance, the Model 3 proved to be far zippier than the Polestar 2, with the Tesla hitting 60 mph in 3.2 seconds and the Polestar 2 taking 4.4 seconds to hit highway speed. Top Gear then mentioned something quite interesting. During their test, they opted to put the Model 3 on Chill Mode for the most part while they were operating the vehicle. But even with Chill Mode, the Model 3 still made the Polestar 2 work hard to keep pace.
“This Tesla is the 450bhp Performance, and it pulled an easy ten lengths on the Polestar off every roundabout or away from each village, but we found ourselves driving it in power-reducing Chill mode most of the time, simply to escape the sudden, neck-straining step-off every time we gently pulled away. It’s very eager. Even in reverse, which is a bit disconcerting. Chill mode smoothed the throttle nicely and still made the Polestar work hard to keep pace,” the publication noted.
One thing that stands out is the fact that unlike the Model 3, which was built as an all-electric vehicle, the Polestar 2 is actually built on Volvo’s CMA architecture, which also underpins the popular XC40. The Polestar 2 is also made with steel panels, which are heavier than the aluminum that’s used in some parts of the Model 3. But despite this, the motoring publication noted that the Polestar, like the Tesla, does not feel heavy on the road at all, thanks to its low center of gravity.
Top Gear did state that there are some areas where the Model 3 falls beneath the Polestar 2. One of these is the vehicles’ interior quality, which is an area where Polestar excels in. Another concerns the two vehicles’ driving dynamics. The publication noted that the softer sprung Tesla gets a bit jiggled from side to side and it does not have impressive body control. The Model 3’s steering was also described as “pretty nasty,” as it has an initial resistance that fades as the driver turns.
The publication noted that the Model 3’s steering could not be described as “sporty or involving,” just effective. On the other hand, the Polestar 2’s steering and controls were described as reassuring in the way that they are “meatier and more satisfying.” But despite these drawbacks, the Model 3 still rides more comfortably compared to the Polestar 2.
The two vehicles also compare very well when it comes to their tech, as the Polestar 2’s Google-powered software experience stands pretty well against Tesla’s custom OS for the Model 3. Both vehicles have robust driver-assist features as well, though Top Gear noted that both Tesla and Volvo’s autonomous efforts still have large areas for improvement. This is especially true for Tesla, which sells a Full Self-Driving suite for the Model 3. Both cars are capable of long-distance travel, thanks to the Supercharger Network and Polestar’s partnership with Plugsurfing. But between the two, the Model 3 provides a faster, easier charging experience.
Ultimately, the Polestar 2 is a stellar effort on Volvo’s part. It’s attractive, well-built, and it carries the best of Volvo’s tech and features in an all-electric package. That being said, Top Gear concluded that ultimately, the Model 3 would likely still be the vehicle to choose if one were looking for an electric car, simply because it provides a more complete ecosystem of ownership.
“The Polestar experience is still very Volvo – and there’s nothing wrong with that. No Volvo drives as well as this, nor oozes more Scandi calmness and cool. It’s pure hygge. I know this is less than analytical but I love what it stands for, what it looks like, it’s the one I’d rather be seen driving and yet… the Tesla wins. Given a straight choice between the two, that’s the one I’d drive away. Nothing to do with its speed or autonomy – the two things usually championed by the Teslarati – but because of its ease of use, efficiency, the supercharger network. It’s the more complete mode of transport,” the magazine noted.

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.
