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.
The Tesla Semi was spotted mounted with ground truth validation equipment as the company nears its looming launch. The Semi is Tesla’s Class 8 all-electric truck, and has been utilized in its earlier stages by many companies like PepsiCo. and Frito-Lay, who have been using it in a pilot program.
The Semi was spotted in Sunnyvale, California, and sports a typical ground truth validation unit that Tesla routinely uses on its vehicles. Ground truth validation is essentially the process of training supervised algorithms to ensure they can perform reliably. Tesla typically performs this on vehicles that are being released soon:
Spotted the new semi adorned with ground truthing equipment. Haven’t seen anyone post this so figured I’d share.

The Semi being spotted with this type of validation rig is important because it means the company is working on solidifying a Full Self-Driving model for its commercial vehicle offering. This would be a massive development for not only Tesla but also the logistics industry as a whole.
There are strict regulations on driving hours for commercial truck drivers, and autonomy is a way to potentially combat these issues. FSD is already a widely effective way that owners of typical passenger vehicles take stress out of travel. Even launching a semi-autonomous platform for truck drivers to use to increase safety, reduce fatigue, and increase productivity would be a huge development.

The Semi has already proven to be an ideal solution for companies that use commercial logistics. It has increased efficiency and reduced operating costs for many companies that have been able to use it in pilot programs.
There are expected to be some bumps along the way. Tesla saw some challenges with FSD on the Cybertruck, as it had never had a vehicle with cameras at that height, so some of the features with FSD were not immediately available. Just a week ago, Tesla launched Actually Smart Summon (ASS) for Cybertruck, nearly three years after the vehicle was first delivered to customers.
President Donald Trump unveiled an upgraded Boeing 747-8 at Joint Base Andrews on June 19, 2026, describing the Qatar-gifted aircraft as an interim Air Force One equipped with advanced communications systems, including Starlink, Elon Musk’s SpaceX satellite internet service.
The plane, valued at around $400 million and modified for presidential use, serves as a bridge until the delayed VC-25B replacements arrive. Trump highlighted its luxury features and new technology during remarks to service members.
Trump stated:
“We have communication equipment up there that nobody’s ever seen before. It’s the highest level and, uh, including Starlink. My friend Elon is going to be very happy, but, uh, Starlink and we have, uh, four or five different sets of double and triple communications like people haven’t seen.”
He added:
“And it represents what can happen with hard work, innovation, and aggressive timelines because we did this quickly and yet there’s never been communication like is on this plane.”
🚨 President Trump confirmed today that the new Air Force One is equipped with Starlink:

The aircraft features a redesigned red, white, and blue livery and has been outfitted with Starlink satellite connectivity alongside other secure systems.
Trump praised the plane’s uniqueness, calling it among the world’s most luxurious. The gift from Qatar and subsequent modifications have drawn attention, with the jet positioned as a solution for presidential travel. It is expected to support operations, including potential ceremonial roles such as Fourth of July flyovers.
The event marked the formal introduction of the converted jet, which will help maintain capabilities while the primary Air Force One fleet undergoes modernization. Defense observers note the inclusion of commercial satellite technology like Starlink as part of efforts to ensure resilient communications, crucial to keep the country running as the President is in the sky.
President Trump’s comments underscored appreciation for rapid upgrades and innovation in equipping the aircraft. The plane remains a U.S. government asset and is slated for eventual transfer related to presidential library purposes after its service.
Tesla just gave what is perhaps its biggest signal yet that the launch of the Cybercab, its autonomous ride-hailing-geared car, is imminent.
The Cybercab has been spotted outside of Gigafactory Texas in massive numbers over the past few days, with hundreds of units being stored on property just days after the vehicle received a Certificate of Conformity from the EPA.
Today, things were a bit different.
Cybercabs spotted on Giga Texas property today had an addition: a Cybercab decal on the side, reminiscent of the “Robotaxi” ones that were placed on Model Ys just as the company launched its ride-sharing platform about a year ago.
Giga Texas drone operator Joe Tegtmeyer noticed the change today:

Tesla could be signaling that the Cybercab is preparing to enter the Robotaxi fleet in the coming weeks or months with this move. It seems more symbolic than anything; Tesla is ready to throw Cybercabs in the ride-hailing platform just as it did with Model Ys last year.
The addition of the Certificate of Conformity awarded to the Cybercab is another major factor working to Tesla’s advantage. The company now has permission from the EPA to allow the vehicle to operate on public roads and enter the chain of commerce. It’s officially street legal.

The big question that remains is whether Tesla will be able to operate the car without a safety monitor, especially considering it plans to put the car out there without a steering wheel or pedals. With the Cybercab only having a seating capacity of two, it is hard to believe Tesla will even consider putting a Safety Monitor in the car.
It did recently self-certify as Level 4 and has the ability to operate driverless vehicles in the State of Texas under a law that took effect on May 28. You can read more about that here:
Tesla’s Robotaxi dreams just took a massive step toward reality
We’d imagine Cybercabs will be on the roads as soon as July, but August will likely be a better estimate of when the car will be entered into the Cybercab fleet. It all depends at where Tesla is, as they’ve truly prioritized safety with the rollout of the Robotaxi platform.
