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 less than 3.5 seconds. Over the course of the drive, several aspects of the vehicle became quite noticeable.

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’s comfort level taking risks makes the stock a ‘must own,’ firm says

Tesla (NASDAQ: TSLA) had coverage initiated on it by a new firm this week, and analysts said that the company’s comfort level with taking risks makes it a “must own” for investors.

Melius Research and analyst Rob Wertheimer initiated coverage of the stock this week with a $520 price target and a “Buy” rating. The price target is about 20 percent higher than the current trading price as shares closed at $435 on Wednesday, up 1.38 percent on the day.

Wertheimer said in the note to investors that introduced their opinion on Tesla shares that the company has a lot going for it, including a prowess in AI, domination in its automotive division, and an incredible expertise in manufacturing and supply chain.

He wrote:

“We see Tesla shares as a must-own. The disruptive force of AI will wreck multitrillion-dollar industries, starting with auto. Under Musk’s leadership, the company is comfortable taking risks. It has manufacturing scale and supply chain expertise that robotics startups possess more by proxy. It can rapidly improve and scale autonomy in driving, the first major manifestation of AI in the physical world.”

However, there were some drawbacks to the stock, according to Wertheimer, including its valuation, which he believes is “challenging” given its fundamentals. He said the $1 trillion market cap that the company represented was “guesswork,” and not necessarily something that could be outlined on paper.

This has been discussed by other analysts in the past, too. Yale School of Management Senior Associate Dean Jeff Sonnenfeld recently called Tesla the “biggest meme stock we’ve ever seen,” by stating:

“This is the biggest meme stock we’ve ever seen. Even at its peak, Amazon was nowhere near this level. The PE on this, well above 200, is just crazy. When you’ve got stocks like Nvidia, the price-earnings ratio is around 25 or 30, and Apple is maybe 35 or 36, Microsoft around the same. I mean, this is way out of line to be at a 220 PE. It’s crazy, and they’ve, I think, put a little too much emphasis on the magic wand of Musk.”

Additionally, J.P. Morgan’s Ryan Brinkman said:

“Tesla shares continue to strike us as having become completely divorced from the fundamentals.”

Some analysts covering Tesla have said they believe the stock is traded on narrative and not necessarily fundamentals.

Tesla launches ‘Mad Max’ Full Self-Driving Speed Profile, its fastest yet

Tesla launched its fastest Full Self-Driving Speed Profile with the v14.1.2 Software Update on Wednesday, as “Mad Max” mode has overtaken “Hurry” as the most spirited travel option on FSD.

On Wednesday evening, Tesla’s Head of AI, Ashok Elluswamy, teased that the v14.1.2 Software Update would be released to those drivers in the Early Access Program (EAP). He said it was a “much-awaited feature.”

Many people, myself included, believed it would be the introduction of “Banish,” which would be a perfect complement to the Actually Smart Summon (ASS) suite, as it would find a parking spot and park itself after dropping you off at the front door of your destination.

However, Elluswamy’s post on X finished with two emojis: one a race car, the other being smoke behind the car.

On Wednesday night, we received the v14.1.2 software update to the new Model Y, which revealed that “Mad Max” mode was the new addition:

The release notes state that:

“Introduced new speed profile MAD MAX, which comes with higher speeds and more frequent lane changes than Hurry.”
It is pretty interesting that Tesla would introduce yet another speed profile that is even faster and more aggressive than “Hurry.” Personally, I’ve found Hurry to be realistic in terms of other drivers and their aggressiveness, speed of travel, and overall lane change behavior, especially on interstates.

Mad Max mode will be an interesting adjustment.

Tesla CEO Elon Musk first talked about Mad Max mode back in 2018 in posts on X, first mentioning the feature with the Tesla Semi:

Musk then teased Mad Max mode in 2019 with an early Autopilot update, stating that it would be an ideal option for aggressive traffic seen in places like Los Angeles. There was formerly a mode of the same name back in the late 2010s:

Now that it’s here, we’ll be testing it very soon and giving you a good idea of what to expect when it releases to others in the coming weeks.

Tesla just teased something crazy with the next Full Self-Driving update

Update 9:56 p.m. ET: We got it…

Tesla launches ‘Mad Max’ Full Self-Driving Speed Profile, its fastest yet

Tesla just teased something crazy with the next Full Self-Driving update, which will be released to Early Access Program (EAP) members today.

Tesla just recently released the v14 Full Self-Driving update, and it followed up just a few days later with v14.1.1.

The subsequent release helped refine a handful of things, especially an issue with stuttering at intersections and overall indecisiveness, but it was more of a smoothing over of the initial v14.1 Full Self-Driving release.

However, on Wednesday evening, Tesla’s Head of AI, Ashok Elluswamy, said that the company would be releasing v14.1.2 to EAP members today, and that it would “debut a much-awaited feature.”

He followed that up with a racecar emoji and a smoke emoji, potentially hinting toward something speed-related. However, it could mean something totally different.

Some suggested it was potentially a new Speed Profile that could rank above the “Hurry” option, but that seems unnecessary. As far as other features that have been teased, one that definitely comes to mind is the “Banish” feature that was recently teased by CEO Elon Musk.

Banish is essentially the finishing touch to Tesla’s Actually Smart Summon (ASS), which launched earlier this year.

While ASS will bring your car to your location using the Tesla app on your phone, Banish does just the opposite by dropping you off at the door of your destination and finding a parking spot on its own.

Elon Musk teases ‘Banish’ feature to pair perfectly with Summon

This was recently teased by Musk yet again, as he said earlier this month that Full Self-Driving would be capable of it very soon.

Based on what we’ve seen out of v14.1 and v14.1.1, there is some potential that Banish could be released and could be the feature that Elluswamy is hinting toward, although there is no direct evidence of that.

Luckily, I was able to get into the EAP, so as the feature is released and the Release Notes are available, we’ll be able to report on exactly what feature is on the way.
