Solar electric yacht builder Silent Yachts has announced an all-electric tender to support its growing lineup of zero-emissions ships. Despite being a tiny vessel, the SILENT Tender 400 was built with the same design standards as Silent Yachts’ larger boats. Built with carbon fiber and up to 30 kW of electric power, the Tender 400 is light and agile, whether it’s sitting on the stern, or transporting up to six people to and from shore. Have a look.
Silent Yachts was founded by Heike and Michael Köhle, who together have sailed over 75,000 nautical miles around the world. Following their extensive travels at sea, the two decided there had to be a better way to propel yachts with clean energy.
After five years of sea trials that began in 2010, Silent Yachts had developed proven solar yacht concept, and began serial production of luxury sustainable vessels in 2016 with the SILENT-64. In the past, we’ve covered Silent Yachts’ larger vessels, like our trip aboard the SILENT-60, which first debuted in 2021.
As the solar electric yacht developer continues to expand into bigger and better at sea, it has shaken things up with a small but mighty electric tender to provide added mobility to its customers.
Silent Yachts’ electric 400 Tender is ultra light and efficient
According to the press release from Silent Yachts, its all-electric SILENT Tender 400 measures four meters from transom to bow and takes a number of design cues from its 60- and 80-foot siblings, including its signature black and white finish.
Thanks to its carbon fiber design, the electric tender weighs just 90 kg (198 lbs), making its easier to lift in and out of the water using the hydraulic platform on the SILENT-60 for instance. Light weight also makes the all-electric SILENT Tender 400 ultra-efficient, offering the capability to transport at speeds over 20 knots. Founder and CEO Michael Köhler elaborated:
We are very proud to present the new SILENT Tender 400, which is one of the most efficient electric tenders on the market. It follows the same design principles as our award-winning electric yachts, with dimensions that enable it to fit both the SILENT 60 series and SILENT 80 series yachts. What is more, the hull gives passengers a really dry ride, even at speed and in confused seas.
Yacht owners who add the electric tender can choose between 20 kW inboard waterjet propulsion system, or a sportier outboard motor capable of 20 or 30 kW. Customers can also choose between a 16 kWh or upgraded 20 kWh lithium battery. Silent Yachts states the electric tender can cruise comfortably at 10 knots for at lease two hours before needing to recharge. With fast charging onboard, the SILENT Tender 400 can replenish in 2.5 hours.
This electric tender is currently designed for the SILENT-60 solar electric yacht, but can also be used on the SILENT-80 or any other yacht. Looking ahed, the company says it is already developing a larger, 5.1 meter electric tender designed specifically for its SILENT-80 series at the request of its customers.

Hyundai’s midsize SUV is already due for a facelift, including a new design and electrified powertrain. It’s not a pure EV, but the new Hyundai Santa Fe will offer electric-only driving.
Is Hyundai launching the Santa Fe EV?
The Santa Fe is slightly bigger than the Tesla Model Y and one of Hyundai’s most popular vehicles, so an EV version would make sense, right?
Hyundai introduced hybrid and plug-in hybrid powertrains for the 2021 model year. The fifth-generation, launched last year, brought a bold new look, added power, and a new hybrid option.
Now, it’s official, the next Santa Fe will be radically different from the current model. A camouflaged prototype was spotted in South Korea with a few design updates, but that’s not all.

Although it’s still under wraps, a sticker on the side of the vehicle confirms that this Santa Fe is actually an extended-range electric vehicle (EREV). Hyundai announced plans to launch its first EREV in 2027 during last month’s CEO Investor Day.

According to Hyundai, the new electrified vehicle will offer an “EV-like” driving experience, delivering over 600 miles (960 km) of combined range.
The vehicle is still equipped with a battery for pure EV driving, but it also has a gas engine that acts as a generator to extend the driving range when the battery gets low. Hyundai will use in-house batteries, which it claims will offer “full EV power performance with less than half the battery capacity.”
The video from HealerTV takes a closer look at the vehicle to show where the battery and high-voltage lines are located.
Although it’s covered, you can see a few design updates, including new head and rear lights that appear closer to the Palisade.
While Hyundai is preparing to launch the Santa Fe EREV, Genesis is also planning to introduce its first extended-range EV. We caught a sneak peek of the Genesis GV70 EREV earlier this month, which is also expected to arrive in 2027. It will follow the luxury brands’ first hybrid, the GV80, due out next year.

In the last week, two former Tesla self-driving/Autopilot program leaders have commented on the state of autonomous driving, telling a very different story than their former boss, Elon Musk.
Elon Musk has been notoriously wrong about predicting when Tesla would solve self-driving.
The CEO first announced that “all Tesla vehicles produced since 2016 have all the hardware necessary to achieve full self-driving,” and then claimed, every year from 2019 to 2025, that Tesla would deliver the capability through software updates by the end of each year.
He reiterated the prediction recently, saying Tesla would remove the safety monitor from its robotaxi service in Austin and enable “unsupervised self-driving” in consumer vehicles by the end of 2025.

There’s been a running gag at Tesla about engineers finding out that the company is supposed to deliver something as Musk announces it publicly – leading to a large discrepancy between what Tesla is working on and what Musk claims it will deliver.
Self-driving has been a good example.
While Musk has repeatedly claimed for the last 6 years that Tesla is on the verge of solving autonomy, the people actually working on the technology are not really in agreement. Some of them who left are starting to speak out.
In a new podcast this week, the AI expect again warned that autonomy is not solved:
He said that he would “push pack” on the idea that what we are seeing in the world of autonomy today, with Tesla and Waymo, means it is a solved problem.
Karpathy said:
“[…] I think basically what takes the long amount of time and the way to think about it is that it’s a march of nines and every single nine is a constant amount of work, so every single nine is the same amount of work, so when you get a demo and something works 90% of the time, that’s just the first nine, and then you need the second nine, and third nine, fourth nine, fifth nine, and while I was at Tesla for five years or so, i think we went through maybe three nines or two nines. I don’t know, but like multiple nines of iteration, there’s still more nines to go, and so that’s why these things take so long […]”
Some data support what the engineer is claiming, as the latest FSD Beta software updates that the Tesla team delivered under his leadership did result in a significant reduction in driver intervention, but the progress has been much less evident since:
The first few ‘9s’ deliver a much greater impact, statistically, than the next ones, even though, as Karpathy pointed out, the next ones are just as important and they are just as tricky as the previous 9s.
While he highlights that there’s still a lot of work to be done, Karpathy did say that he belives Tesla’s approach to be more scalable.
He is not the only former Tesla Autopilot program leader to speak out recently.
Sterling Anderson is recognized as the first Autopilot program leader at Tesla in 2015-2016. He now leads global products at GM, which announced this week that it plans to launch level 3 autonomous driving in 2028.
During the event announcing the new autonomous driving timeline at GM, Anderson took a jab at his former employer:
Our customers have driven over 700 million hands-free miles with Super Cruise without a single accident attributed to the technology. I led Autopilot, and you can’t say that for Autopilot. I think this is the long-term play: we build trust with customers by delivering safe products.
The GM executive favor the more careful approach to autnomous driving.
Electrek’s Take
As I often point out, there’s what Elon says, and there’s what Tesla’s lawyers say.
Elon’s own lawyers say Tesla shareholders shouldn’t listen to him, calling his statements “mere corporate puffery.” That’s an actual quote.
I do believe that Tesla will achieve unsupervised self-driving in consumer vehicles at someone point, but I don’t have any evidence that it is close to happen.
As Karpathy said, there are still several 9s to go through before it can be at 99.9999999%, which is needed for level4-5 autonomy, and each of those 9s represent years of work.
I think there’s a clear discrepenacy between how Elon talks about self-driving at Tesla and what people who are actually building those systems, like Anderson and Karpathy from 2015 to 2022, are experiencing.
Elon has been lucky to find Ashok, Tesla’s current self-driving leader, who seems to be perfectly willing to endorse his consistently wrong FSD predictions.
It’s not really surprising when you know that Ashok is the one who produce the infamous FSD demo of 2016. As Karpathy pointed out, we should be doubtful of AI demos.
Looking the prediction markets, people don’t really believe in what Elon is claiming. On Polymarket, people who have been betting on Tesla’s not delivering unsupervised self-driving this year have made a lot of money:
Elon reitereted the goal this week and the “no” answer still gained ground after his claim that Tesla was on track.
