Porsche Taycan Turbo regen braking and sound details teased in first ride
The Porsche Taycan is nearing its official reveal, and the German carmaker is currently conducting the all-electric car’s final tests. As the vehicle’s last details get ironed out, auto publication CNET Roadshow was able to get an opportunity to ride shotgun in one of Porsche’s Taycan prototypes in Sweden, to experience the company’s next-generation vehicle firsthand.
The publication was able to take a ride in a test mule of the Taycan’s top-tier variant, a version speculated to be dubbed as the “Taycan Turbo.” Just as revealed in previous sightings, the Taycan Turbo boasts 600 horsepower with an all-wheel-drive powertrain that enables 0-60 mph times of
The Porsche Taycan will utilize a regenerative braking system that is quite different from those used by popular electric cars like the Tesla Model S, which engage their regen braking when the driver releases the accelerator. The Taycan does not do this, as the vehicle only coasts when the accelerator is released. The Taycan’s regenerative braking only happens when drivers press lightly on the brake pedal. When the brakes are pressed harder, the Taycan’s hydraulic brakes are engaged.
Bernd Propfe, director of the Taycan’s platform product line, described the process to the publication. “Coasting is the most energy-efficient way to do it, because braking always goes along with a loss of energy, because no engine has a 100 percent ratio. We strongly believe that the customer, if he wants to brake, he should hit the brake,” he said.
While such a strategy will make one pedal driving impossible with the Taycan, the vehicle’s regenerative braking process is distinctly on-brand. Porsche prides itself as a maker of drivers’ cars, and requiring its customers to actively use both the accelerator and brake pedal while operating the Taycan could be considered part of the all-electric sedan’s genuine driving experience.
Also unique in the Taycan is the vehicle’s two-speed transmission at the rear. Electric cars like the Model S utilize a single gear transmission, partly due to the power generated by the vehicle’s electric motors. Tesla attempted a two-speed transmission in the original Roadster back in 2008, only to abandon the design after the transmission units showed a tendency to self-destruct just a fraction into the all-electric sports car’s lifespan. If Porsche’s design with the Taycan is any indication, it appears that the German carmaker is confident that it can use a two-speed transmission for the all-electric four-door sedan without compromising anything.
Propfe proved quite secretive when it came to the Taycan’s sound, only stating that it will be digitally created and it will change depending on the specific mode of the all-electric car. The platform line director added that the Taycan’s sound is still very much in development. Fortunately, this sound was captured recently in a sighting of a Taycan test mule in Copenhagen, Denmark. While taking off on a parking lot ramp, the Taycan gave off a truly unique noise that invoked a mix between a traditional high-performance sports car and a spaceship.
The Taycan’s sound is best heard firsthand. Make sure to keep the volume up.
And here’s CNET Roadshow‘s segment on its first ride with the Taycan.

Tesla launches Cybertruck vehicle-to-grid program in Texas
The initiative was announced by the official Tesla Energy account on social media platform X.
Tesla has launched a vehicle-to-grid (V2G) program in Texas, allowing eligible Cybertruck owners to send energy back to the grid during high-demand events and receive compensation on their utility bills.
The initiative, dubbed Powershare Grid Support, was announced by the official Tesla Energy account on social media platform X.
Texas’ Cybertruck V2G program
In its post on X, Tesla Energy confirmed that vehicle-to-grid functionality is “coming soon,” starting with select Texas markets. Under the new Powershare Grid Support program, owners of the Cybertruck equipped with Powershare home backup hardware can opt in through the Tesla app and participate in short-notice grid stress events.
During these events, the Cybertruck automatically discharges excess energy back to the grid, supporting local utilities such as CenterPoint Energy and Oncor. In return, participants receive compensation in the form of bill credits. Tesla noted that the program is currently invitation-only as part of an early adopter rollout.
The launch builds on the Cybertruck’s existing Powershare capability, which allows the vehicle to provide up to 11.5 kW of power for home backup. Tesla added that the program is expected to expand to California next, with eligibility tied to utilities such as PG&E, SCE, and SDG&E.
Powershare Grid Support
To participate in Texas, Cybertruck owners must live in areas served by CenterPoint Energy or Oncor, have Powershare equipment installed, enroll in the Tesla Electric Drive plan, and opt in through the Tesla app. Once enrolled, vehicles would be able to contribute power during high-demand events, helping stabilize the grid.
Tesla noted that events may occur with little notice, so participants are encouraged to keep their Cybertrucks plugged in when at home and to manage their discharge limits based on personal needs. Compensation varies depending on the electricity plan, similar to how Powerwall owners in some regions have earned substantial credits by participating in Virtual Power Plant (VPP) programs.

Samsung nears Tesla AI chip ramp with early approval at TX factory
This marks a key step towards the tech giant’s production of Tesla’s next-generation AI5 chips in the United States.
Samsung has received temporary approval to begin limited operations at its semiconductor plant in Taylor, Texas.
This marks a key step towards the tech giant’s production of Tesla’s next-generation AI5 chips in the United States.
Samsung clears early operations hurdle
As noted in a report from Korea JoongAng Daily, Samsung Electronics has secured temporary certificates of occupancy (TCOs) for a portion of its semiconductor facility in Taylor. This should allow the facility to start operations ahead of full completion later this year.
City officials confirmed that approximately 88,000 square feet of Samsung’s Fab 1 building has received temporary approval, with additional areas expected to follow. The overall timeline for permitting the remaining sections has not yet been finalized.
Samsung’s Taylor facility is expected to manufacture Tesla’s AI5 chips once mass production begins in the second half of the year. The facility is also expected to produce Tesla’s upcoming AI6 chips.
Tesla CEO Elon Musk recently stated that the design for AI5 is nearly complete, and the development of AI6 is already underway. Musk has previously outlined an aggressive roadmap targeting nine-month design cycles for successive generations of its AI chips.
Samsung’s U.S. expansion
Construction at the Taylor site remains on schedule. Reports indicate Samsung plans to begin testing extreme ultraviolet (EUV) lithography equipment next month, a critical step for producing advanced 2-nanometer semiconductors.
Samsung is expected to complete 6 million square feet of floor space at the site by the end of this year, with an additional 1 million square feet planned by 2028. The full campus spans more than 1,200 acres.
Beyond Tesla, Samsung Foundry is also pursuing additional U.S. customers as demand for AI and high-performance computing chips accelerates. Company executives have stated that Samsung is looking to achieve more than 130% growth in 2-nanometer chip orders this year.
One of Samsung’s biggest rivals, TSMC, is also looking to expand its footprint in the United States, with reports suggesting that the company is considering expanding its Arizona facility to as many as 11 total plants. TSMC is also expected to produce Tesla’s AI5 chips.

Anti-Tesla union leader ditches X, urges use of Threads instead
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Marie Nilsson, chair of Sweden’s IF Metall union and a prominent critic of Tesla, has left X and is urging audiences to follow the union on Meta’s Threads instead.
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Anti-Tesla union leader exits X
In a comment to Dagens Arbete (DA), Nilsson noted that her exit from X is not formally tied to IF Metall’s long-running labor dispute with Tesla Sweden. Still, she stated that her departure is affected by changes to the platform under Elon Musk’s leadership.
“We have stayed because many journalists pick up news there. But as more and more people have left X, we have felt that the standard has now been reached on that platform,” she said.
Jesper Pettersson, press officer at IF Metall, highlighted that the union’s departure from X is only indirectly linked to Tesla Sweden and Elon Musk. “Indirectly it does, since there is a lot of evidence that his ownership has caused the change in the platform to be so significant.
“We have nevertheless assessed that the platform had value for reaching journalists, politicians and other opinion leaders. But it is a microscopic proportion of the public and our members who are there, and now that value has decreased,” Petterson added.
IF Metall sees Threads as an X alternative
After leaving X, IF Metall has begun using Threads, Meta’s alternative to the social media platform. The union described the move as experimental, noting that it is still evaluating how effective the platform will be for outreach and visibility.
Pettersson acknowledged that Meta also does not operate under Sweden’s collective bargaining model, but said the union sees little alternative if it wants to remain visible online.
“In a perfect world, all large international companies would be supporters of the Swedish model when they come here. But unfortunately, the reality is not like that. If we are to be visible at all in this social media world, we have to play by the rules of the game. The alternative would be to become completely invisible, and that would not benefit our members,” he said.
