Porsche has shown off its electric GT4 ePerformance racecar at an ice track race in Sweden.

As a leader in vehicles that put a smile on your face, Porsche is under distinct pressure to bring that same excitement and joy to the EV transition, and it’s clear that it intends to do just that. First shown at the Goodwood Festival of Speed last year, the Porsche GT4 ePerformance has made another debut, this time at an ice track race in Northern Sweden.

At the Race of Champions event in Northern Sweden, Porsche got the opportunity to show off its GT4 ePerformance project, a car that is set to define the future of electric motorsports.

The Porsche GT4 ePerformance is a serious racecar, no question about it. Fitted with carbon fiber body panels, the tried and true aerodynamics of Porsche’s fastest racecars, and a stripped interior, it is the real deal and has the performance to back it up.

The full specifications of the vehicle are not yet known, but a surprising amount of information has been revealed over the past year. First of all, the ePerformance is designed to last a minimum of 30 minutes on the racetrack, what Porsche says is the equivalent of 1 Porsche Carera Cup race, allowing drivers to push the car to its absolute limit without the worry of a dead battery mid-race.

Second, the drivetrain, likely using a dual or tri-motor system, produces similarly insane power as its gas counterparts. It packs 603 horsepower for its 30-minute race setting or up to 1088 horsepower peak. But perhaps even more surprising is the car’s incredibly quick charging. According to Porsche engineers, the vehicle can charge from 5 to 8 percent in as little as 15 minutes thanks to its 900-volt architecture.

While Porsche did not provide a statement on the vehicle or today’s race for that matter, Porsche’s Project Manager of Sales Oliver Schwab told Teslarati:

“The 718 Cayman GT4 ePerformance blazes a trail to Porsche customer racing with electrically-powered racing cars. As a first step, we will unveil this concept to our global partners. With drivers, teams, organizers, authorities, and other interested parties, we’re also gathering ideas for Porsche racing formats in the future.”

To show off this incredible power, Porsche chose the ideal venue. For those unfamiliar, the “Race of Champions” (ROC) is a series of races that take place around the globe, forcing the best drivers on the planet to face off; on the same track, same car, and same day. This event includes participants such as four-time F1 Champion Sebastian Vettel, six-time American rally champion Travis Pastrana, ten-time F1 Champion Valtteri Botas, nine-time 24 Hour of LeMans winner Tom Kristenson, need I say more.

But merely coming to the event was not nearly enough for the thrill junkies from Stuttgart. The GT4 ePerformance was fitted with spiked tires and one of the largest wings I have ever seen mounted on a Porsche vehicle, allowing the car to rip and jump through the icy course with ease.

If this is the future of motorsport, I want it.

And thankfully, I (and many others) won’t have to wait much longer. While unconfirmed by Porsche, the high-performance electric 911 could very well make its production debut following the introduction of the company’s newest EV platform, PPE. And with the numerous benefits to handling, power efficiency, and weight reduction, the car could be a rocket ship.

According to a Porsche press release from late last year, the GT4 ePerformance will be headed to North America for the first half of this year, making a tour throughout the continent to show potential customers the incredible future of electric Porsche racing, and will ultimately end up in Asia after completing its grand tour.

Porsche has shown in today’s video that motorsports are here to stay and may flourish with the upcoming EV transition. With such a noble goal, who could oppose them? Who knows, with the dedication to its electric performance vehicle offerings, it might just be enough to drag a certain American EV maker to the same market. And if this product is a showing of Porsche’s future products, such a competitor might finally have something to worry about.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry

Tesla set to launch “Terafab Project: A vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.

Published

Tesla is making one of the boldest bets in its history. On March 14, Elon Musk posted on X that the “Terafab Project launches in 7 days,” pointing to March 21, 2026 as the start date for what he has described as a vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.

Tesla first confirmed Terafab on its January 28, 2026 earnings call, where Musk told investors the company needs to build a chip fabrication facility to avoid a supply constraint projected to materialize within three to four years. But the seeds were planted even earlier. At Tesla’s annual general meeting last year, Musk warned that even in the best-case scenario for chip production from their suppliers, it still wouldn’t be enough, and declared that building a “gigantic chip fab” simply had to be done.

While there has been no official announcement on where Tesla plans to break ground on the massive Terafab, all signs point to the North Campus of Giga Texas in Austin.

Months of speculation has surrounded Tesla’s North Campus expansion at Giga Texas, where drone footage captured by observer Joe Tegtmeyer revealed massive construction site preparation just north of the existing factory on a scale that rivals the original Giga Texas footprint itself.

Samsung’s Tesla AI5/AI6 chip factory to start key equipment tests in March: report

The project is projected to produce 100–200 billion AI and memory chips annually, targeting 100,000 wafer starts per month, at an estimated cost of $20 billion. Tesla is targeting 2-nanometre process technology and anticipated to be the most advanced node currently in commercial production. Dubbed the Tesla AI5 chip, the chip will pack 40x–50x more compute performance and 9x more memory than AI4, and will be among the first products Terafab factory is set to produce. This highly optimized, and massively powerful inference chip is designed to make full self-driving (FSD) and Tesla’s Optimus robots faster, safer, and with full autonomy.

This is where Terafab becomes a genuine game-changer. If Tesla successfully builds a 2nm chip fab at scale, it becomes one of only a handful of entities that’s capable of producing AI silicon in-house, with competitive implications that extend far beyond Tesla’s own vehicles, and potentially positioning Tesla as a chip supplier or licensor to other industries.

The next-gen Tesla AI chips will power advancements in Full Self-Driving software, the Cybercab Robotaxi program, and the Optimus humanoid robot line. Musk’s projections for Optimus require chip volumes that no existing external supplier can commit to on Tesla’s timeline.Competitors like Waymo and GM’s Cruise remain dependent on third-party silicon, leaving them exposed to the same supply chain vulnerabilities Tesla is now working to eliminate entirely.

The Terafab launch this week may not mean a factory opens its doors overnight, but it signals Tesla is serious about owning the entire AI stack, from software to silicon.

Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.

This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.

Tesla announces massive investment into xAI

At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.

xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.

When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.

Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI

The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.

Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.

Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.

It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.

Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.

By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.

As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.

In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.

It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Tesla is adding an awesome new driving feature to Model Y vehicles, effective on Juniper-updated models considered model year 2026 or newer.

Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.

Tesla writes in the release notes for the feature:

“Your Tesla now provides a smoother feel as you come to a complete stop during routine braking.”

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.

There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.

This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.

Tesla set to activate long-awaited Cybertruck feature

Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.

Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.

We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.
