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.
For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.
It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.
Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.
The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.
Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.
The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.
SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.
There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.
The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.
Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.
The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.
On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.
Tesla Cybercab has one important piece that AI4 cars might need for FSD
It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:
“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.
It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something
There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.
Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.
Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.
Here are the full release notes for the suite:
- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
- Introduced parking, unparking, and reversing capabilities.
- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
- Speed Profiles are now available at all times, to further customize driving style preference.
These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.

He added:
“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.
