Watch out Flipper. U-Boat Worx has announced major performance improvements to its fully-electric, three-passenger Super Sub, donning it “the most flow-dynamic submersible the world has ever seen.” With these improvements to flow dynamics, U-Boat Worx states the electric sub is now 3-4 knots faster than the cruising speed of a bottlenose dolphin.
U-Boat Worx is a Dutch submersible manufacturer that began as a dream by founder Bert Houtman in the 1980s. Today, the company is one of the industry leaders in sub design and electric versions in particular.
U-Boat Worx handles submersible design, construction, and operations for militaries, research institutes, and tourism companies. Since 2017, the electric submarine specialist has sold over twenty of its Cruise Subs to private customers, resorts, and cruise lines.
U-Boat Worx currently offers six different series of submarines, all of which are electric. This includes the nine-passenger NEXUS series we previously covered, as well as the three-passenger Super Sub which first debuted in 2021.
Today, U-Boat Worx has showcased the scientific work that went into a redesign of the Super Sub to bolster its speed below the water’s surface.

Flow dynamics testing
U-Boat Worx’s faster electric Super Sub to launch in 2023
While U-Boat Worx has yet to provide the video evidence it is claiming the upcoming version of its Super Sub can cruise as quickly as 10 knots, 3-4 knots faster than the bottlenose dolphin. In addition to a streamlined design, speed comes from a four thruster propulsion system delivering 60 kW of thrust.
This flow dynamic optimization is also a welcomed improvement from the speed of eight knots the submersible developer was originally estimating. At top speed, the electric Super Sub can cruise about seven knots faster than the average submersible, and now has the same flow dynamics as an electric car. Company CEO Bert Houtman spoke:
We are very excited about this development. It’s something we have been working hard on, and now to have the most flow-dynamic submersible possible, we couldn’t be more pleased. We are confident that our clients will feel the same.
U-Boat Worx originally introduced the Super Sub as its fastest and most maneuverable design to date. When the revamped versions begin to deliver in 2023, those passengers are in for even faster journeys through the sea at depths as low as 300 meters.
The company states the first new Super Sub has already been sold, and it plans to begin sea trials this coming spring. Perhaps then we can see this electric submersible go fin to fin with a dolphin.

BYD’s new EV is about the size of a Tesla Model 3, but half the cost in China. After launching the e7, BYD is already boasting that it will be the “winner’s choice” for midsize EV sedans. Here’s our first look at the new low-cost electric sedan.
Will the new BYD e7 EV rival the Tesla Model 3 in China?
After previewing the e7 for the first time a little over a month ago, BYD officially launched the midsize electric sedan on Saturday.
The new e7 is available in three “Smart” trims, starting at 103,800 yuan, or about $14,500. For a limited time, BYD is offering a renewal price of 99,800 yuan ($13,900).
Buyers can choose from two BYD Blade battery options: 48 or 57.8 kWh, providing CLTC driving ranges of 450 and 520 km, respectively.

BYD’s new midsize EV sedan is about the size of a Tesla Model 3: 4,780 mm long, 1,900 mm wide, 1,515 mm tall, and 2,820 mm wheelbase.
Although it looks similar to other BYD models, the e7 has a few unique design elements, including a “Smiling and high-spirited” front face design, full-score LED headlights, and a duck tail.
We knew it would be a lower-priced EV after the preview showed the e7 with traditional door handles, rather than the flush ones found on newer models.
Like BYD’s other new vehicles, the interior is relatively simple with a 15.6″ central infotainment at the center and a 5″ driver display cluster. It’s also loaded with the advanced version of BYD’s smart cockpit and DiLink100.
The “ingeniously crafted comfortable cockpit,” as BYD calls it, is available with ergonomic cloud-sensing seats, an integrated hand gear, and a panoramic sunroof.
Although the e7 is part of BYD’s e-series, a lower-priced lineup aimed at younger drivers or taxi services, it’s now being absorbed into its Ocean series with other popular EVs like the Dolphin and Seagull.
BYD’s new EV is over half the cost of a base Tesla Model 3 RWD model in China, which starts at 235,500 yuan ($32,700). But, to be fair, the base Model 3 has a CLTC driving range of up to 634 km (394 miles). For 275,500 yuan ($38,200), the Model 3 Long Range AWD is rated with up to 713 km (443 miles) CLTC range.

Hyundai is gaining traction where most automakers are struggling to stay afloat. Despite a flood of low-cost electric cars and an intensifying price war, Hyundai sees an opportunity “to write a new chapter” with its first dedicated EV rolling out in China.
Will Hyundai’s new EV spark a comeback in China?
Leading up to its debut, we thought it could be the IONIQ 4 with a sleek new look. The ELEXIO is Hyundai’s first custom-tailored EV for China.
During its global debut earlier this month in Shanghai, Hyundai said China is a “must-fight place,” calling it “the core of Hyundai Motor’s global strategy.” The company also revealed its “In China, for China, to the World” strategy as it looks to make a comeback in the world’s largest EV market.
According to Hyundai, the company is already seeing early success. On Monday, Hyundai’s joint venture in China, Beijing Hyundai, announced that its losses improved by over 100 billion won ($72 million) in the first quarter.

The company posted a net loss of 42.3 billion won in the first three months of 2025, down from the massive 146 billion won ($105 million) in Q1 2024. At this pace, Hyundai could see a profit by the second quarter in China.

Hyundai said lower operating costs spurred the cost improvements after the company sold its Chongqing plant last year.
It’s also due to rising exports. Beijing Hyundai exported 14,999 vehicles in Q1, up significantly from just 608 a year ago. Hyundai’s Chinese JV is investing 8 billion yuan ( $1.1 billion) as it looks to revamp the business.
Although it’s already seeing some success, Hyundai’s new ELEXIO electric SUV is expected to accelerate its momentum. With the EV launching in the second half of 2025, Hyundai could turn a profit by the end of the year. It may even happen as early as the second quarter.
Hyundai claims the new EV opens “a new starting point for the transformation from traditional fuel vehicle giant to electrification” in China.
The ELEXIO electric SUV, dubbed the Chinese version of its popular IONIQ 5, rocks a new look with crystal cube LED headlights and a full-length light bar that stretches across the front.
Based on Hyundai’s E-GMP platform, which powers the IONIQ 5, the ELEXIO is rated with up to 435 miles (700 km) CLTC driving range. More details, including prices and trim options, will be revealed closer to launch. Check back soon for the latest.
What do you think of Hyundai’s new electric SUV? Would you buy the ELEXIO in Europe, the US, or other global markets? Let us know in the comments.
Tesla announced it paid Powerwall owners $9.9 million through its virtual power plant programs in 2024.
Distributed energy is working.
A virtual power plant (VPP) consists of distributed energy storage systems, like Tesla Powerwalls, used in concert to provide grid services and avoid the use of polluting and expensive peaker power plants.
Peaker plants are fossil fuel-powered power plants that are activated in peak energy usage times to ensure the grid has enough power to supply the demand and avoid brownouts.

It is a fairly new technology that aims to decentralize the grid, helping make it more secure and stable while reducing costs.
Tesla has been an early adopter of the technology through the deployment of its Powerwall, a popular home battery pack.
In areas with high penetration of the home battery, Tesla can make a deal with the local electric utility to pull power from the Powerwalls in customer homes when needed, and those homeowners get compensated at an attractive rate.
Today, Tesla announced that it paid Powerwall owners nearly $10 million through VPPs in 2024:
We paid out $9.9M to Powerwall owners who supported the grid through Virtual Power Plant participation in 2024.
Tesla’s first VPP launched in Australia in 2019. The company first aimed for 50,000 homes, but we learned that it is at about 7,000 homes and 35 MW as of the end of last year when Tesla was looking to sell the virtual power plant.
In 2021, Tesla launched a VPP pilot program in California, in which Powerwall owners would voluntarily and without compensation let the VPP pull power from their battery packs when the grid needed it.
It helped Tesla prove the usefulness of such a system.
This new version of the Tesla Virtual Power Plant actually compensates Powerwall owners $2 per kWh that they contribute to the grid during emergency load reduction events. Homeowners are expected to get between $10 and $60 per event.
Some Powerwall owners are now reporting making hundreds of dollars per year per Powerwall through Tesla’s virtual power plant.
Electrek’s Take
This is awesome. I love distributed energy. VPPs not only make home energy storage more financially viable, but they also often mean that fossil fuel-powered peaker plants are being replaced by solar power and energy storage, as most Powerwalls and other home battery packs are linked to home solar power.
It’s not super popular yet because it requires the cooperation of the electric utilities and the regulators, but it appears to be viable in most places.
If you have home solar and energy storage, or looking to add solar and energy storage at home, it’s worth looking into.
