Porsche flexes e-Motorsport prowess with GT4 ‘ePerfomance’
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 Model 3 and Model Y can now do what only Cybertruck could
Tesla Model 3 and Model Y can power your home with Powerwall 3 during outages.
Tesla has turned its two top sellers into backup batteries for the house.
Tesla Energy announced on Tuesday that Powershare Home Backup is now available for new Model 3 and Model Y vehicles paired with a Powerwall 3, saying the car can “extend your home backup by over 2 days.” Minutes later, Tesla’s main account quoted the post with a broader pitch: “With Powerwall 3, every Tesla can now serve as your home’s backup battery.”
Until this week, the Cybertruck was the only Tesla that could send power back into a home, and that capability only began working alongside Powerwall 3 last month, after years of ambitious targets.
Tesla’s updated Powershare page says every Model 3 and Model Y ordered in the U.S. or Puerto Rico on or after October 1, 2026 can use the feature. Some, but not all, earlier cars also qualify. Owners can check on the touchscreen under Software, then Additional Vehicle Information, where a capable car shows “Powershare Support: Enabled.” As Electrek reported, bidirectional power on the two cars runs through an inverter Tesla calls PCS2 Lite, and the company has not said when that part entered production on each trim.
The home side is simpler. A house that already has a Powerwall 3 and either a Wall Connector 3 or Universal Wall Connector needs no additional equipment, and Tesla says compatibility is enabled through a software update. When the grid drops, the Powerwall and the car work together, with up to 11.52 kW of continuous power available. Tesla’s “over two days” estimate assumes a home using 30 kWh per day and a car starting at a 90 percent charge. Standard trims are rated for up to two days, while the Cybertruck adds more than three.
There are limits. Powerwall 2 and Powerwall+ support is listed as “coming soon.” Model S and Model X are not included, and Grid Support, the program that lets Cybertruck owners in Texas send power back to the grid during demand spikes for bill credits, is not available for Model 3 or Model Y.
The rollout also lines up with something Elon Musk said more than three years ago. At Tesla’s March 2023 Investor Day, Musk said, “I don’t think very many people are going to want to use bidirectional charging, unless you have a Powerwall.” Tesla has now shipped the feature for its volume cars with exactly that requirement attached.
The Powerwall pairing was the hard part on Cybertruck. Tesla told owners in December 2025 that Powershare with Powerwall had been pushed to mid 2026, and lead engineer Wes Morrill explained that two devices capable of forming a home’s grid have to negotiate which one leads during an outage, across multiple generations of hardware. With that work done for the truck, Tesla was able to extend it to the Model 3 and Model Y within a month.
Ford and GM have offered home backup from their EVs for several years, but both require a separate inverter and backup hardware. Tesla’s version leans on equipment many Powerwall 3 owners already have on the wall. Powershare for the two cars also ships as part of software update 2026.38.3, the same release that began delivering Halloween Mode on Tuesday.
Tesla is now starting to ship a “Halloween Mode” that is filled with some creepy and fun features; the company says, “This spooky update turns your Tesla into a haunted house on wheels.”
The update is just the latest in a series of updates that Tesla typically ships out in a seasonal fashion. The Spring and Summer Updates provided some fun novelty items while also packing some cool features that are actually useful for the ownership experience.
This one seems to be more fun-forward, and there are not any updates to the Full Self-Driving suite or overall operation of the vehicle. Instead, these novelty features are geared toward getting you in the mood for the Fall and Halloween.

SpaceX reveals how its 1 Million AI satellite network will work and prevent space collisions
SpaceX reveals plans for one million Starmind AI satellites and calls out operators hiding maneuvers.
SpaceX has put the largest satellite count it has ever published into writing, and it says that plan only works if every other operator in orbit starts sharing what it knows.
In a new Space Safety page highlighted Tuesday morning by Sawyer Merritt on X, SpaceX said it “plans to operate up to 100,000 Starlink satellites and up to 1 million Starmind AI satellites to meet the growing demand for broadband and supercompute.” Starlink has a little over 11,000 satellites in orbit today, so the target alone implies roughly a ninefold expansion of the broadband network.
Starmind is SpaceX’s orbital AI compute constellation. Elon Musk confirmed the Starmind name in June after an xAI trademark filing surfaced, and in August SpaceX said it was working with Nvidia on the compute payload. The FCC accepted the filing for up to one million satellites back in February.
FCC accepts SpaceX filing for 1 million orbital data center plan
SpaceX also released a new render of what a full Starmind constellation could look like. Alongside it, SpaceX VP Michael Nicolls explained why the satellites will not operate on their own. “We need to operate clusters of satellites in tight formation to get enough coherent compute to run AI models efficiently,” Nicolls said. “A cluster will be 10-ish satellites connected with 10 terabits or so of bandwidth between them, and interconnected to the broader constellation.”
That is the most specific detail SpaceX has given on how Starmind will be built. Instead of a million independent servers, the network would work as tightly packed groups of about 10 satellites acting as one compute unit, with Starlink’s laser links carrying results back to Earth.
There is a bright and exciting future for humanity ahead – and space is fundamental to that future.
To achieve this, space safety must be done right. We encourage every operator to not only share ephemeris data proactively the same way Starlink already does, but to also adopt the high standards of space safety that SpaceX and Starlink use every day → https://t.co/QizAkQZvEm
— Starlink (@Starlink) October 6, 2026
Packing satellites that close together, at that scale, makes collision avoidance the central problem, and most of the Space Safety page is aimed at other operators. SpaceX said Starlink encountered collision risks with about 650 unique maneuvering third party satellites in 2026, and only about half of them shared data. Over six months, Starlink recorded roughly 164,000 more collision risks where the closest approach came within four hours of an unannounced maneuver.
Some operators keep maneuver plans private over proprietary concerns, while others cannot get government permission to share them. SpaceX called those policies “counterproductive,” saying they “largely only serve to create preventable collision risk between satellites.” Starlink is also offering a free ephemeris sharing and screening platform that returns risk results within a minute, backed by its Stargaze network of 30,000 optical sensors.
The push comes as the Starmind application draws opposition from astronomers and environmental groups. In a September filing with the FCC, SpaceX said each Starmind satellite could weigh up to 4,000 kg, nearly seven times the mass of a Starlink V2 Mini. Musk has brushed off crowding concerns before, telling viewers in June that “space is enormous” and that SpaceX already knows how to run very large constellations safely.
SpaceX’s Starmind page says its Gigasat factory in Bastrop, Texas, is designed to produce AI satellites at scale, with deployment of thousands of units starting as soon as late 2027.
