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.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
