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.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.
🚨 A Tesla Semi reportedly caught fire, with California Highway Patrol confirming. The Semi was on I-880 SB

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
