After Tesla delivered the first 12 of its highly anticipated Cybertruck this week, one automotive reviewer took the truck to the race track against two competitors in the electric pickup segment.

The Tesla Cybertruck “Cyberbeast” version got the full review and drag race treatment from Hagerty this week after the automaker delivered the vehicle’s first units on Thursday. In the video, auto journalist Jason Cammisa takes the Cybertruck up against rival electric pickups, the Rivian R1T and the GMC Hummer electric vehicle (EV).

Along with the Cybertruck including notable features such as its steer-by-wire handling, its 800-volt architecture, Powershare, and the option for a range extender, Cammissa starts with the R1T and Hummer drag races, emphasizing the truck’s impressive acceleration speeds.

As Cammisa points out, the Cybertruck was designed to offer driving dynamics matching a Porsche 911, while featuring more utility than a traditional pickup truck. Although Cammisa says it doesn’t quite drive like a 911, he says it may be faster than one, noting later that the Beast Mode Cybertruck is the quickest-accelerating pickup in history — both in its 0-60 mph and 1/4-mile times (landing at 2.6 seconds and 11 seconds, respectively).

Cammisa also points out that only one of the motors in the Cybertruck uses permanent magnets, unlike the four included in the R1T. Instead, the Cybertruck sports two induction motors in the rear, substantially reducing the rare earth metals needed. Tesla and other automakers have already announced plans to reduce the use of rare earth materials in future EVs.

Although the Porsche Taycan added 800v architecture in 2019, Cammisa brings on “Engineering Explained” host Jason Fenske to discuss how high voltage helps Tesla save money on Cybertruck materials. In addition, Cammisa notes that Tesla also quadrupled the Cybertruck’s low voltage from 12v to 48v, resulting in reduced material needs and effectively marking the first time in history an automaker has increased an EV’s low voltage capacity.

Since the industry has had a difficult time switching to 48-volt architecture, Tesla also sent a cheeky manual to other OEMs with the title “How To Design a 48-volt Vehicle.”

Cammisa goes on to discuss several other features of the Cybertruck, including its steer-by-wire handling and turn radius, the vehicle’s safety and crash preparedness, and a handful of interior details, among others.

In the steer-by-wire portion of the video, Cammisa talks about the Cybertruck being the first production vehicle to have no physical connection between the steering wheel and the front wheels. On Saturday, the video section was also reposted on X by CEO Elon Musk.

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’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.

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.
