Trucks With Onboard Solar Are Becoming A Thing
Every time I write about solar vehicles, I get the same thing from people in the comments and on social media, like:
“That’s a stupid gimmick that’ll add like a mile a day.”
“What a joke. That can’t even run the air conditioning.”
While these statements have been true for decades, solar technology and EV efficiency have slowly been chipping away at the problem. Now, vehicles like the “never charge” Aptera and the Sono Sion are proving that solar can power at least a good chunk of people’s driving — but can it work for larger vehicles?
The answer isn’t a hard “No” like it once was. The amount of “Yes” is on the rise, even for people who don’t want to drive a “clown truck.”

Earlier this month, Sono Motors worked with ARI to add solar to a 458 “Box Body” truck. While not a full-sized truck, or even a normal-sized truck, it’s still an incredibly useful little beast. In cities, at airports, or just for the last mile of package delivery, the 458 Box Body can carry almost 1200 pounds (531 kg) and up to 2.8 cubic meters (about 100 cubic feet) of cargo. It can go a maximum of 80 km/h (about 50 MPH) and has a range of 75–300 miles on a charge.
At full throttle, the 458 Box Truck uses only 7.5 kW of electric power, but most driving would be with far less current. So, it’s really an ideal platform to experiment with solar drive power.
Sono took the stock 458 Box Truck and added solar modules made with ultra-thin, chemically-stressed front glass to provide up to 450 watts of energy at peak performance. Under normal conditions in Munich, they figure that it will add 20 km of range daily without plugging in, and up to 45 km of range under more ideal conditions like you’d find in the US Southwest.

“Sono Solar — Sono Motors’ B2B unit — is a one-stop-shop for vehicle integrated photovoltaics (ViPV) and our aim is to make every vehicle a solar vehicle. The Intersolar exhibition is the perfect platform to show our proprietary technology and services and we are very pleased to be able to present existing partnerships and prototypes like the electric ARI transporter,” says Mathieu Baudrit, Sono Solar Group Lead at Sono Motors.
Fraunhofer Is Testing A Larger Solar Truck
When it comes to cargo trucks, Justin Hammer was right. Size does matter. Don’t let anyone tell you differently. In ‘Murica, we need a big 9,000 pound truck just to go to the store and buy kitty litter. Don’t believe me? Ask GM about the Hummer EV. Clown cars like the 458 Box Truck might be useful for the city parks and recreation department to drive around the baseball fields, or for the airport to stuff tiny meals into planes with, but don’t expect to see them on the road.
When it comes to doing a real man’s man work, we want to be like Rubber Duck in the 1978 movie Convoy. “My daddy always told me to be like a duck. Stay smooth on the surface and paddle like the devil underneath!” If we can’t push 80,000 lb down the road while strung out on caffeine and modafinil (among other things) while eating an echo-modded radio microphone and saying “Breaker one nine!” on 27.185 MHz AM with an illegal 600-watt linear amplifier that makes the lights go dim when you key it up, it’s just not good enough.
I’m kidding about most of the above, of course. While the Hummer EV does weigh in at 9,000 pounds, and we really do love our big vehicles, almost nobody even knows what most of the last paragraph even means. You’ll just have to watch the YouTube video and hang out at truck stops a little more to see if I’m making stuff up.
Many reasonable, sane people who wouldn’t ram the New Mexico State Police or the Illinois National Guard out of the way, and who want to carry cargo for an honest living, do really need a larger vehicle than the 458 Box Truck. Where’s the solar panel for us “Rubber Ducks?”

Fortunately, the industry is working on giving even the biggest trucks some juice from the giant thermonuclear fireball in the sky. Fraunhofer has an electric truck driving on German roads right now with 3500 watts of solar power on the trailer. Sure, it’s no 18-wheeler, but 18 tons GVWR is nothing to sneeze at either. The 3.5 kilowatts of power only takes care of 5–10 percent of the electric truck’s energy needs.
“By successfully putting our high-voltage photovoltaic system into operation, we have achieved our goal of demonstrating the feasibility of vehicle-integrated photovoltaics for heavy-duty electric utility vehicles. The technical components integrated into the truck function as we expected,” said Christoph Kutter, project manager at Fraunhofer ISE.
There is one small safety risk, though. To directly charge the truck’s traction battery, the panels are wired in series, and put out that 3500 watts of power at over 400 volts. In the event of an accident, that’s a lot of juice to be randomly flipping around in the face of emergency workers and good Samaritan types. Fraunhofer thought ahead and installed an automatic disconnect that cuts every solar panel off from the whole system, reducing the voltage down to safe levels.
Feeding 5–10% of the vehicle’s needs from solar might seem sort of silly, but Fraunhofer plans to run the truck hauling real loads for a year on German roads to collect data. By collecting the data on how much solar power ends up being generated, used, and replaced, they can get a much better idea of how to build better solar vehicles in the future as the technology improves.
After all, solar panels are getting better all the time, and it will eventually be possible to take care of a significant portion of the truck’s power. Plus, trucks operating in cities and trucks that spend a lot of time sitting during the day will benefit even more from this technology.
So, fear not, Rubber Ducks. The power of the sun will soon be yours!

LiveWire, the electric motorcycle brand spun out of Harley-Davidson, has just given us a closer look than ever at its upcoming lower-cost, smaller-format electric motorcycles ahead of their larger unveiling at the Milan Motorcycle Show (EICMA) next week.
While we got our first glimpse of the new machines earlier this summer, spotting a street and trail version of the smaller electric motorbikes, now we have a name for the models and a few more details.
Officially called the S4 Honcho, the new model will be a 125-cc equivalent that will be available in both a street-legal version capable of being operated by riders who possess a moped/light motorcycle license in Europe or a motorcycle license in the US, and a license-free off-road version.
“The S4 Honcho Street will qualify for A1 licenses in Europe and the UK and M-endorsement in the U.S., offering lightweight, urban-friendly electric mobility with intuitive performance and removable batteries,” explained the company.
The bikes appear to be powered by a centrally-mounted, chain-driving electric motor and a pair of removable batteries accessed by flipping up the seat.
LiveWire has remained fairly tight-lipped regarding the major tech specs for the bikes, as well as the price, but we do get a look at the dual removable batteries thanks to a new image posted to the company’s website.
There, we can see what appears suspiciously similar to a pair of KYMCO Ionex batteries, which would make sense given LiveWire’s close partnership with the Taiwanese scooter giant.
A couple years ago at EICMA I had the chance to check out KYMCO’s new Ionex batteries and e-scooter platform firsthand, which you can see in the video below.
While excitement has been building for LiveWire’s smaller electric motorcycles, the full unveiling of the bikes’ performance figures as well as the price tag will prove critical for gauging whether or not the mini-bikes could be a major turning point for LiveWire’s elusive profitability.
But the company isn’t betting it all on one horse, or one Honcho. Also in attendance at the show will be LiveWire’s full-scale concept of an electric maxiscooter built on the same S2 architecture that powers the company’s currently best-selling models, the S2 Del Mar, S2 Mulholland, and S2 Alpinista.
That scooter, built in partnership with KYMCO, will leverage the company’s fully developed S2 platform to create a more comfortable, high-performance urban and suburban-oriented model.

Tesla is talking about finally bringing the next-generation Roadster to production in new job listing.
However, you shouldn’t hold your breath.
The prototype for the next-generation Tesla Roadster was unveiled in 2017 and was supposed to enter production in 2020, but it has been delayed each year since then.
It has become a running gag in the Tesla community and an example of CEO Elon Musk’s tendency to stretch the truth about timelines.
Since missing its original 2020 production timeline, Musk has given six updated production timelines for the new electric supercar, and each has been wrong.
The latest timeline hasn’t even been about producing the vehicle. It has been about the unveiling of a new version of the next-generation as the last prototype of what is supposed to be a “next-gen” car was unveiled almost a decade ago.
Musk has been talking about an unveiling and demonstration of the New Roadster by the end of the year.
This week, Tesla has posted a new job listing for a ‘Manufacturing Engineer, Roadster‘. In the job description, Tesla mentions working on battery manufacturing equipment for the Roadster:
Tesla is looking to hire a Manufacturing Engineer to contribute to the concept development and launch of battery manufacturing equipment for our cutting-edge Roadster vehicle. In this role you will take large scale manufacturing systems for new battery products and architectures from the early concept development stage through equipment launch, optimization and handover to local operations teams. Battery development is at the heart of our company, and this is an exciting opportunity to work directly on the central challenges for the all-new Roadster product architecture while still in its early development stages.
The comment does point to Tesla starting to set up manufacturing for the production of the new Roadster.
Since this does sound like early manufacturing development work, it would be optimistic to hope to see new Roadsters rolling off the production line by the end of next year. More likely to be in 2027.
In its updated annual installed production capacity chart, Tesla listed Roadster production as still being in the “design development” phase as of last week:
The location of Roadster production is also listed as “to be determined.”
The new job listing for a manufacturing engineer on the Roadster program mentions being based in Fremont, which could mean Tesla plans to launch production at its California factory.
Tesla next-gen Roadster
As unveiled in 2017, the new Roadster was supposed to get 620 miles (1,000 km) of range and accelerate from 0 to 60 mph in 1.9 seconds.
It was listed for $200,000, and a “Founder Series” was also offered for $250,000.
At the time, Tesla used the Roadster as a prize for its referral program when it badly needed to generate sales. A few dozen Tesla owners referred enough new sales to win one or two free new Roadsters each.
Some have suspected that Tesla didn’t want to bring the vehicle to production because it would have to deliver over 30 of them for free and hundreds more at heavy discounts due to its original referral program.
Others believe that updates to the vehicles have led to delays.
Shortly after the unveiling of the next-gen Roadster in 2017, Musk discussed adding cold-air thrusters to the supercar to deliver unprecedented racing performance and possibly even allow it to hover over the ground.
The CEO referenced demonstrating that the “Roadster can fly” on several occasions in the last few years.
Electrek’s Take
It looks like we are talking about the Roadster possibly coming to market in 2027—maybe late 2026 at the earliest.
That’s roughly 10 years after it was unveiled.
I’ll believe it when I see it. And if it does happen, I might have one or two flying Roasters for sale.

Just like it says on the tine: TV brand SHARP is following Sony into the automotive space with the new LDK+ concept that transforms into a mobile movie theater. It’s a type of concept we’ve seen before – but not like this!
The SHARP LDK+ promises to be a Living room, a Dining room, and a Kitchen on wheels – and more (the plus, obviously), building off the decidedly more blobular™ concept first shown back in 2024. This updated version, however, takes the LDK concept and brings it significantly closer to reality by basing it on Foxconn’s “Model A EV by Hon Hai Technology Group” chassis.
And, now that it’s a little bit closer to some kind of reality, it might be time to climb on the SHARP hype train and take a minute to genuinely enjoy the movie/gaming environment the company is promising to deliver with the LDK+ concept.
Get hyped, kids
Not to be overly crude here, but if you roll in a van with a sliding projector table, opaque windows, and fully reclining seats, you probably hit the “family planning” section of your local Walgreens on a regular basis. Similarly, as more and more young people find themselves struggling to afford their own space, offering a vehicle that delivers a little privacy. And even if that’s more Netflix than chill, I think it’s bound to find a few buyers.
Whether I’m right or wrong about that will remain to be seen for a while, however. The official press release is light on specs, offering the following description of the LDK+ concept …
The second iteration of “LDK+” retains the original concept while featuring both high maneuverability with its compact body and a spacious, relaxing interior. Developed based on the“Model A” EV by Hon Hai Technology Group (Foxconn), this compact minivan model offers an expansive cabin layout.
When parked, the vehicle can be used as a theater room or a remote workspace. A console box equipped with a table and projector is placed between the driver’s and passenger’s seats. By swiveling the driver’s seat to face backward, it creates a living room-like atmosphere where you can sit around with the rear seats. Pulling down the screen installed above the rear seats allows you to enjoy movies or conduct online meetings on a large display. Through Sharp’s AIoT platform, which connects AI and home appliances, the vehicle links with household devices such as kitchen appliances, air conditioning, and laundry systems. The AI learns residents’ lifestyles and preferences, creating personalized new ways of living. In addition, the system can connect with V2H (Vehicle to Home) solutions, enabling efficient energy management by integrating solar power generation and residential storage batteries.
SHARP
… but skipping automotive basics like battery capacity, anticipated driving range, and the usual horsepower and torque figures. Pricing and, perhaps most importantly, when the vehicle might see the light of day weren’t revealed, either.
SHARP LDK+ concept
All of which is to say: they’re probably never going to actually build something like this – and that’s too bad, because a new-age Honda Element/Nissan Cube-style boxy little EV would absolutely sell like hotcakes.
