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.

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.

Oil prices jump more than 3%, adding to last week’s surge, as Israel strikes Iran energy facilities

Oil prices jump more than 3%, adding to last week's surge, as Israel strikes Iran energy facilities

Crude oil futures jumped more than 3% Sunday after Israel struck two natural gas facilities in Iran, raising fears that the war will expand to energy infrastructure and disrupt supplies in the region.

U.S. crude oil rose $2.72, or 3.7%, to $75.67 per barrel. Global benchmark Brent was up $3.67, or 4.94%, at $77.90 per barrel.

Israeli unmanned aerial vehicles struck the South Pars gas field in southern Iran on Saturday, according to Iranian state media reports. The strikes hit two natural gas processing facilities, according to state media.

It is unclear how much damage was done to the facilities. South Pars is one of the largest natural gas fields in the world. Israel also hit a major oil depot near Tehran, sources told The Jerusalem Post.

Iranian missiles, meanwhile, damaged a major oil refinery in Haifa, according to The Times of Israel.

Oil prices closed more than 7% higher Friday, after Israel launched a wave of airstrikes against Iran’s nuclear and ballistic missile programs as well as its senior military leadership.

It was the biggest single-day move for the oil market since March 2022 after Russia launched its full-scale invasion of Ukraine. U.S. crude oil jumped 13% in total last week.

The war has entered its third day with little sign that Israel or Iran will back down, as they exchanged barrages of missile fire throughout the weekend.

Iran is considering shutting down the Strait of Hormuz, a senior commander said on Saturday. About one-fifth of the world’s oil is transported through the strait on its way to global markets, according to Goldman Sachs. A closure of the strait could push oil prices above $100 per barrel, according to Goldman.

However, some analysts are skeptical Iran has the capability to close the strait.

“I’ve heard assessments that it would be very difficult for the Iranians to close the Strait of Hormuz, given the presence of the U.S Fifth Fleet in Bahrain,” Helima Croft, global head of commodity strategy at RBC Capital Markets, told CNBC’s “Squawk Box” on Friday.

“But they could target tankers there, they could mine the straits,” Croft said.

Next Generation Kenworth electric semi truck now available with Bendix ADAS

Kenworth has announced the addition of Bendix’ Fusion advanced driver assist system (ADAS) to its line of options on the T680 line of Class 8 commercial semi trucks – a lineup that includes the Next Generation T680E battery electric semi truck.

One of the many new trucks revealed at the 2025 ACT Expo in Anaheim, California earlier this year, the Next Generation Kenworth T680E featured the latest advancements in battery-electric technology, an enhanced exterior design, and a suite of new, in-cab technology that extends to the addition of three Bendix Fusion version: ADAS, ADAS PRO, and ADAS PREMIER.

All three of the announced ADAS packages offer updated Adaptive Cruise Control (ACC) with ACC Stop and Auto Go™, a new Pedestrian Autonomous Emergency Braking (PAEB) feature, and a new High Beam Assist feature to reduce the likelihood of blinding oncoming drivers supported by the addition of a new forward-looking camera.

Those updates are in addition to the ADAS units Autonomous Emergency Braking (AEB), Multi-Lane Autonomous Emergency Braking, Highway Departure Braking (HDB), and Stationary Vehicle Braking (SVB), Lane Departure Warning, and Bendix® Blindspotter® Side Object Detection already available on previous versions of the ADAS-equipped Kenworth.

Now that we’ve got that acronym-loaded word-salad out of the way, we can get to the point: the newest generation of electric trucks is easier and safer to drive – and not just safer for the truck’s operators, but for the people who share the roads with them, too.

The Next-Generation T680E is available with up to 605 peak hp and 1,850 lb-ft of torque from a PACCAR Integrated ePowertrain fed from a 500 kWh li-ion battery pack good for more than 200 miles of loaded range. The updated Class 8 BEV is rated up to 82,000 lb. gross vehicle weight ratings (GVWR), and can get that load back up to speed quickly with a 350 kW peak charge rate that means the T680E can charge up to 90% in just two hours.

That system isn’t just more efficient than the first generation truck, it’s also more serviceable than it was before.

“This move to a fully integrated and ground-up PACCAR design means we were able to design for enhanced serviceability,” explains Joe Adams, Kenworth’s chief engineer. “Providing easier access to the Master Service Disconnects for improved safety and increased uptime and allowing the use of the DAVIE service tool for troubleshooting and diagnostics.”

The Next Generation Kenworth T680E electric semi truck is designed for short and regional-haul, LTL, and drayage operations. It’s available as a day cab as either a tractor or straight truck in a 6×4 axle configuration.

Dealers are slashing prices on 2025 Kia Niro EV, nearly 25% off!

Dealers are slashing prices on 2025 Kia Niro EV, nearly 25% off!

Just like it says on the tin – retailers are advertising killer deals on the fun-to-drive Kia Niro EV, with one midwest auto dealer reporting more than $10,000 off the sticker price of the Niro EV Wind. That’s nearly 25% off the top line price!

SKIP THE STORYget straight to the deals.

The Kia Niro EV gets overshadowed by its objectively excellent EV6 and EV9 stablemates – both of which are currently available with substantial lease cash and 0% APR financing, in fact – but that doesn’t mean it’s not an excellent little electric runabout in its own right.

The last time I had a Niro EV tester, my kids loved it, I liked that it was quicker and more tossable than I expected it to be, and my wife liked the fact that “it doesn’t look electric. It looks normal.” And, with well over 200 miles of real world range (EPA-rated range is 253 miles), it was more than up to the task of commuting around Chicago and making the trip up to the Great Wolf Lodge in Gurnee and back without even needing to look for a charger.

It’s not the primary family hauler I’d choose – but as a second car? As a primary car for a slightly smaller family (1-2 kids, instead of 3-4)? The Kia Niro EV Wind, with a $42,470 MSRP, seems like a solid, “can’t go wrong” sort of choice. You know?

You won’t even have to pay that much, though. Raymond Kia in Antioch, Illinois is advertising a $42,470 Niro EV for $32,431 (that’s $10,039, or about 24% off the MSRP), and several others are advertising prices in the $33,000 range.

And, while we’re at it:
