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.

To start, we have NIU’s BQi-C3 Pro e-bike that not only offers up to 90 miles of travel (and a bunch of solid features), but is also dropping down to a new $999 low. Behind it is Segway’s latest flagship release, the Ninebot Max G3 Electric Scooter, which is getting a $400 post-launch discount to $1,000. There’s also Leviton’s NACS to J1772 EV Charger Adaptor dropping to $32, as well as the popular Greenworks 40V 16-inch Cordless Push Lawn Mower that comes with a 4.0Ah battery for $210. Plus, all the other hangover Green Deals from last week are in the links at the bottom of the page, collected together in our Electrified Weekly roundup – but don’t miss out on the many sales that are ending tonight!

Head below for other New Green Deals we’ve found today and, of course, Electrek’s best EV buying and leasing deals. Also, check out the new Electrek Tesla Shop for the best deals on Tesla accessories.

Get a long-traveling budget-friendly commuter in NIU’s BQi3-C3 Pro e-bike at a new $999 low

Best Buy is offering the best rate yet on the NIU BQi-C3 Pro e-bike for $999 shipped. Normally posted up at a $2,200 price tag, this e-bike has been more frequently seen discounted between $1,300 and $1,500 on average, with the $1,299 low appearing more often too since first appearing in June. Today’s deal though takes costs lower than we’ve ever seen them with a 55% markdown that puts $1,201 back into your pocket for a new all-time low and the best price we have currently find.

With three colorways to choose from – black, white, or grey – NIU’s BQi-C3 Pro e-bike offers up some solid commuting power at a far more affordable rate than many other models with similar capabilities. The streamlined frame houses dual integrated 10.0Ah batteries that work alongside the 750W rear hub motor and Gates carbon belt to provide top speeds of 28 MPH for up to 90 miles on a single five-hour charge when its three PAS levels are being utilized.

Your ride is further enhanced by the extra features you’ll find here, like the integrated rear cargo rack, front suspension, puncture-resistant tires, and a 3.5-inch TFT color display. Along with these, you’ll also find fenders over both those tires, an LED headlight and taillight, a kickstand, and mechanical disc brakes – plus, all its wiring is internally routed for a cleaner look on top of the motor’s IP65 waterproof rating and the batteries’ IP67 rating.

Segway Ninebot Max G3 Electric Scooter

Segway’s new Ninebot Max G3 e-scooter with Apple Find My and autonomous locking falls to $1,000

Amazon is now offering the new Segway Ninebot Max G3 Electric Scooter for $999.99 shipped. Coming down from its $1,400 price tag, this all-new flagship e-scooter just officially hit the market a week ago after having a pre-launch sale that saw it drop to $900. If you missed out on those pre-sale savings this is the next-best price we have seen, cutting $400 off the going rate to give you the second-lowest price we have tracked and even coming in $100 under Segway’s direct site.

Picking up the mantle from the Max G2, Segway’s all-new Ninebot Max G3 brings some impressive upgrades to your commute, starting with an 800W motor that can peak all the way to 2,000W, tackling up to 30% inclines at top speeds up to 28 MPH. By activating its Boost Mode, acceleration is pushed to its max, getting you up to 15.5 MPH in 2.4 seconds before increasing further up to its top speed. With the 597Wh battery that it’s been given, travel distance has been bumped up to 50 miles on only 3.5 hours of charging, which is due to the built-in fast-charger – plus, by connecting a DC charger cable for simultaneous charging, you can hop back on to ride in a shorter 2.5-hour timeframe.

Among its upgraded features you’ll find improved handling, disturbance resistance, and slip resistance at any speed thanks to the Stability Enhancement System here. Two notable standout features though, are the Apple Find My inclusion alongside the autonomous locking/unlocking functionality, which you can adjust in terms of its activation via your distance from it. There’s also the dual suspension, 11-inch self-sealing tires, the automatic 6W headlight, underglow deck lighting, and a 2,4-inch smart TFT display which provides navigation, caller IC, and smart charge management through your phone.

Leviton NACS to J1772 EV charger adaptor

Add Leviton’s NACS to J1772 EV adapter to your glove box for wider charging access at $32

As part of its Big Spring Sale, Amazon is having a Lightning deal on the Leviton NACS to J1772 EV Charger Adapter for $31.60 Prime shipped, with non-members needing a cart total of over $35 to score the free shipping. This handy little adapter normally keeps up at its $39 MSRP, which is getting a solid 19% markdown here today for as long as supplies last. What few discounts we’ve seen have mostly kept prices above $35, though December did see a drop to the $31.20 low that repeated once at the top of the month. You’re looking at the second-lowest price we have tracked here today, which comes in just $0.40 above the lowest ever.

If you’re sticking with your Tesla or any NACS-centered EV and want to expand your charging options, this might be a good adapter to have tucked away in your glove box. You’ll gain access to any charging station that sports J1772 connectors – so trips visiting friends and family with such setups no longer need planning around should you need to top of your EV’s battery. Not only is it designed to have no problems in indoor and outdoor environments, regardless of the season, but it also allows for up to 60A charging speeds when in use.

Greenworks 40V 16-inch cordless electric push lawn mower

Get lawn care support on a budget with Greenworks’ 40V 16-inch cordless push mower at $210

As part of its Big Spring Sale, Amazon is offering the Greenworks 40V 16-inch Cordless Push Lawn Mower with a 4.0Ah battery for $209.99 shipped. This model has been keeping down at $300 lately, a drop-off from its usual $330 price tag, with the discounts in 2025 mostly dropping costs between $250 and $225, though there have been occasional returns to this same rate, which we last spotted in February. While we have seen it go lower in the past, you’re still looking at the best price on Amazon for the last year, saving you $90 ($120 off its previous price tag) while also getting you prepped for mowing duties throughout the warmer months ahead. It’s even beating out Greenwrok’s direct site by $90.

This 40V Greenworks push lawn mower is a budget-friendly model that is perfect for smaller yards, as the included 4.0Ah battery provides it with enough juice for 45 minutes of runtime on a single charge, though you can certainly switch it out with others to extend performance. There are five cutting height positions that you can choose from here, ranging from 1 1/4 inches to 3 3/8 inches, with the push button start eliminating the need to wrestle with pull-strings and the foldable frame saving you storage space. It even provides two different collection options, mulching or rear-bagging, giving you more versatility over single-function counterparts.

Best New Year EV deals!

Best new Green Deals landing this week

The savings this week are also continuing to a collection of other markdowns. To the same tune as the offers above, these all help you take a more energy-conscious approach to your routine. Winter means you can lock in even better off-season price cuts on electric tools for the lawn while saving on EVs and tons of other gear.

Home solar buyers are asking for Tesla Powerwall alternatives

Home solar buyers are asking for Tesla Powerwall alternatives

New data from EnergySage shows that home solar buyers are increasingly asking for Tesla Powerwall alternatives as the brand damage extends to Tesla’s energy business.

Tesla has long been the brand leader in home battery packs with Powerwall.

The automaker launched its energy division in 2015 with the release of the first Powerwall, which help greatly expand the home battery pack market.

With Powerwall 2, Tesla Energy became the market leader and with Powerwall 3 last year, the company achieveied a truly impressive production ramp – albeit not without some questions.

It remains the most popular option for people looking for home backup power or to make better use of their home solar system, but there’s competition and Tesla’s brand issues are turning people to those competitors.

EnergySage is a service that enables homeowners to easily source and compare solar quotes for free without any sales call.

It gives them a lot of data about the home solar and battery industry.

The company says that homeowners have consistently chosen the Powerwall when adding a battery to their quote, but it has gone down since Trump’s inauguration and Musk’s salutes:

From January 1 through January 19, about 73% of homeowners selected a battery quote that included the Tesla Powerwall. That number dropped to 64% between January 20 and March 10.

Futhermore, EnergySage says that it has seen a surge in people mentioning Tesla in the quote process and 68% specifically asked for a Tesla Powerwall alternative:

Homeowners receiving quotes mentioned Tesla more than twice as often in emails in the first two months of 2025 compared to the same time last year; 13.5% expressed unfavorable views towards Tesla or Musk, while 68% specifically requested a Tesla alternative.

EnergySage shared an example of one such message from one of its clients:

“Do you offer a battery from a supplier other than Tesla? Though we have a Tesla Powerwall and love it, and we love our Tesla Model 3 and Y, we are outraged at Musk’s politics, so we don’t wish to send him more money,”

North Carolina-based Renu Energy Solutions says that 78% of the home batteries it installed last year were Tesla’s Powerwalls.

Nicholas Boles, Solar Energy Advisor Manager at Renu, confirmed that they are now seeing a surge in requests for alternative this year.

Boles said that they are now pushing Franklin batteries as a Tesla alternative:

“The last 14 deals I’ve sold as a manager have all been Franklin batteries.”

The Franklin aPower 2 has very similar specs as the Powerwall 3 with a bit more energy capacity and a bit less power capacity, but it also has a better warranty:

Specification Tesla Powerwall 3 Franklin aPower 2
Energy Capacity 13.5 kWh 15 kWh
Continuous Power Output Up to 11.5 kW 10 kW
Peak Power Output Up to 30 kW (for 10 seconds) up to 15 kW
Load Start Capability 185 A Locked Rotor Amps (LRA) Supports up to a 5-ton A/C unit
Scalability Up to 4 units Up to 15 units per system (225 kWh total)
Battery Chemistry Lithium Iron Phosphate (LFP) Lithium Iron Phosphate (LFP)
Round-Trip Efficiency 89% (solar to battery to home/grid) Not specified
Operating Temperature Range -4°F to 122°F (-20°C to 50°C) -4°F to 131°F (-20°C to 55°C)
Dimensions (H x W x D) 43.25 in x 24 in x 7.6 in (1099 mm x 609 mm x 193 mm) 45.2 in x 29.5 in x 11.8 in (1149 mm x 750 mm x 300 mm)
Weight 287 lbs (130 kg) 357 lbs (162 kg)
Enclosure Rating Not specified IP67 (battery pack & inverter); IP56 (wiring)
Warranty 10 years 15 years or 60 MWh throughput

While there’s evidence that Tesla’s brand issues are pushing more people to alternative, it is still clear that Powerwall remains popular.

Kowalczyk of Solartime USA told EnergySage that the Texas-based solar installers still gets more requests for Powerwalls than any other battery system.

Electrek’s Take

It makes sense that Tesla’s brand issues would also affect its energy business. Megapack being a business-to-business product isolates from the brand issues, but the Powerwall is still a consumer product.

However, the Powerwall was already so dominant that even significant brand issues would still result in significant market share for Tesla.

There’s also a lack of competition, but they are coming. Franklin aPower 2 is a good example as it fairly close in price and specs as Powerwall 3.

That said, with the still growing home solar business as people are trying to avoid increasing electricity rates. Tesla isn’t likely to have a demand issue with the Powerwall anytime soon.

If you are interested in getting solar and/or batteries for your home, we recommend using EnergySage. You will be able to get quotes without any hassle and only talk to someone when you are ready to move forward.

Genesis will launch the GV80 EV we’ve been waiting for, but first a hybrid is coming soon

Genesis will launch the GV80 EV we've been waiting for, but first a hybrid is coming soon

The luxury Genesis GV80 SUV is finally getting an EV variant. Genesis is launching the next-gen model as soon as next year. For the first time, it will be available as a hybrid. An all-new, fully electric GV80 is set to follow.

When is Genesis launching the GV80 EV?

Genesis has emerged as a dark horse in the luxury segment as the auto industry continues shifting toward electrification.

Although Genesis initially planned to launch all new vehicles exclusively as EVs, starting this year, that will no longer be the case.

Hyundai’s luxury brand will introduce a series of hybrids after it “overachieved” in the EV department. Genesis now plans to launch hybrids for as many models as possible, including the GV80. After sales of the midsize luxury SUV hit a new global record in the first half of 2024, Genesis is preparing to launch an updated model.

According to South Korean blogger MotorsJason, the next-gen Genesis GV80 will debut in 2026 or 2027 with a new 2.5L hybrid variant.

Currently, the SUV is only available in 2.5-liter four-cylinder or twin-turbo 3.5-liter V6 options. A hybrid variant will likely help boost the midsize SUV’s appeal even more.

Genesis will follow up with an all-new GV80 EV, which is expected to launch in 2028. The electric SUV will reportedly be built on Hyundai’s new eM platform, set to replace its current E-GMP.

Although details are slim at this point, Hyundai’s new EV platform is expected to boost range and charging speeds while cutting costs. It’s designed for vehicles of all sizes, from sedans to pickups. The platform will also underpin the upcoming ultra-luxury Genesis GV90.

At 4,940 mm long, 1,975 mm wide, and 1,715 mm tall, the Genesis GV80 is about the size of a BMW iX (4,952 mm long, 1,967 mm wide, and 1,695 mm tall) or slightly bigger than the Tesla Model Y and Porsche Macan EV.

Genesis is also reportedly working on an electric G70 sports sedan. Like the GV80 EV, it likely won’t arrive until 2027 or 2028.

Can the Genesis GV80 EV compete with the BMW iX or upcoming Porsche Cayenne EV? Let us know what you think in the comments.
