"Reservation holders, it's finally time to get ready," writes long-time Slashdot reader AirHog. The EV news site Electrek reports: Aptera Motors, "the little startup that could," announced another important milestone... completing the first example of its flagship solar EV on its validation assembly line in Southern California... While the validation line at its headquarters remains a low-volume assembly process, its successful operation represents the startup's transition from hand-built validation SEVs to a more structured assembly line process that will be fine-tuned for mass production... With low-volume assembly now being validated, Aptera is starting to publicly utter encouraging terms like "EPA certification" and, better yet, that holy grail of "initial customer deliveries." Before then, however, the Aptera Solar EVs built on this low-volume validation line will be used for testing programs such as thermal validation, brake performance, and "some destructive testing." Aptera shared that its assembly and integration team has grown to become the largest at the startup, "reflecting the beginning of its transition from engineering development to testing and production execution"... As of March 2026, Aptera says it has over 50,000 reservations totaling over $2 billion in sales if all were to solidify following the launch of a deliverable vehicle. Clean Technica notes the vehicles' "generous cargo space that comes out to 60% more storage than a Honda Accord and 20% more storage than a Prius, according to the company." "Built with recyclable materials, this eco-friendly vehicle features a lightweight carbon fiber structure and no-welding assembly for maximum cost and production efficiency," Aptera adds. The emphasis on lightweighting supports the goal of engineering a car that can travel on the electricity provided by its onboard solar panels. The company currently advertises that the vehicle can travel 40 miles on solar power alone, with the battery providing extra juice as needed. Ideally, the car can keep recharging itself with sunlight, further elongating the time between charging sessions... [Its range is up to 1,000 miles with plug-in charging.] The new autocycle could also appeal to drivers who enjoy the challenge of hypermiling, which involves deploying a suite of driving techniques to minimize fuel consumption. Hypermiling can apply to gas-powered cars, but the magic really kicks in with the regenerative braking capability of EVs. Aptera's onboard solar panels add another dimension to the fun.

United Airlines has updated its contract of carriage to require passengers to use headphones when playing audio or video on personal devices during flights. Travelers who refuse could be removed from the plane or even permanently banned from flying with the airline, reports CBS News. United notes that it will offer customers who forget theirs a free pair of wired earbuds. "Don't worry if you forget your headphones for your flight," the airline states on its website. "If they're available, you can request free earbuds." You'd better hope your device still has a headphone jack... Further reading: Flying Was Already the Worst. Then America Stopped Using Headphones.

Longtime Slashdot reader linuxwrangler writes: Dark Reading reports that a team of researchers has determined that signals from tire pressure monitoring systems (TPMSs), required in U.S. cars since 2007, can be used to track the presence, type, weight, and driving pattern of vehicles. The researchers report (PDF) that the TPMS data, which includes unique sensor IDs, is sent in clear text without authentication and can be intercepted 40-50 meters from a vehicle using devices costing $100. "Researchers have discovered that most TPMS sensors transmit a unique identifier in clear text that never changes during the lifetime of the tire," the researchers pointed out. "This unencrypted wireless communication makes the signals susceptible to eavesdropping and potential tracking by any third party in proximity to the car."

If U.S. automakers turn their backs on electric vehicles, "their sales outside the U.S. will shrivel," warns Bloomberg. [Alternate URL.] They're already falling behind on the technology, relying on a 100% U.S. tariff on Chinese EVs to keep surging rivals like BYD Co. at bay.... While the American automakers "mostly understand the challenge in front of them, they don't have full plans" to confront it [said Mark Wakefield, head of the global automotive practice at consultant AlixPartners]... "Now is a great time for the V-8 engine," said Ryan Shaughnessy, the Mustang's brand manager. "We've done extensive customer research in multiple cities, looking at a variety of powertrains, and the V-8 is always the number-one choice." It isn't just customers. U.S. automakers have long been run by "car guys:" enthusiasts who live for the bone-shaking rumble of a big engine. For them, quiet and smooth EVs — even the absurdly fast ones — can't satisfy that craving. They're convinced many American car buyers share the same enthusiasm for what Shaughnessy described as "the sound and roar of the V-8." Wall Street couldn't be happier with the new direction... Ford's fortunes are also on the rise, as it's predicting operating profits could grow by as much as 47% this year to $10 billion. Ford's stock has risen nearly 50% over the last 12 months. Under the previous environmental rules, automakers effectively had to sell zero-emission vehicles in growing numbers to offset their gas-guzzlers. When they fell short, they had to buy regulatory credits from EV companies such as Tesla Inc. or face penalties. GM spent $3.5 billion on credits from 2022 to the middle of 2025. Now, according to JPMorgan Chase & Co. analyst Ryan Brinkman, GM and Ford each have "billion dollar tailwinds"... [T]he hangover from all that new horsepower could leave US automakers lagging their Chinese rivals who already build the world's most advanced — and lowest priced — electric cars. Indeed, there is much talk in Detroit about the competitive tsunami that will be unleashed on American automakers once Chinese car companies find a way to break through trade barriers now protecting the US market. [Ford Chief Executive Officer Jim] Farley even calls it an "existential threat"... "They're going to build as many V-8 engines and big trucks as they can get out the factory doors," said Sam Fiorani, vice president of vehicle forecasting for consultant Auto Forecast Solutions. "And as the rest of the world develops modern drivetrains, newer batteries and better electric vehicles, GM and Ford in particular are going to find themselves falling even further behind." The article notes GM "continues to develop battery-powered vehicles, and CEO Mary Barra said the automaker would begin offering a 'handful' of hybrids soon," while Ford and Stellantis "have plans to launch extended-range electric vehicles, or EREVs, a new kind of plug-in hybrid with an internal combustion engine that recharges the battery as the vehicle drives down the road." But while automakers may be investing in future EV vehicles, they're also "leaning into the lucre that comes from selling millions of fossil-fuel vehicles in a rare moment of loosened regulation."

Fossil fuels produce NO2, which is linked to asthma attacks, bronchitis, and higher risks of heart disease and stroke, according the EV news site Electrek. But the nonprofit news site Grist.org notes a new analysis showing that those emissions decreased by 1.1% for every increase of 200 electric vehicles — across nearly 1,700 ZIP codes. "A pretty small addition of cars at the ZIP code level led to a decline in air pollution," said Sandrah Eckel, a public health professor at the University of Southern California's Keck School of Medicine and lead author of the study. "It's remarkable." The study was done at the University of Southern California's medical school, by researchers using high-resolution satellite data, reports Electrek: The study, just published in The Lancet Planetary Health and partly funded by the National Institutes of Health, adds rare real-world evidence to a claim that's often taken for granted — that EVs don't just cut carbon over time, they also improve local air quality right now... The researchers ran multiple checks to make sure the trend wasn't driven by unrelated factors. They accounted for pandemic-era changes by excluding 2020 in some analyses and controlling for gas prices and work-from-home patterns. They also saw the expected counterexample: neighborhoods that added more gas-powered vehicles experienced increases in pollution. The findings were then replicated using updated ground-level air monitoring data dating back to 2012... Next, the researchers plan to compare EV adoption with asthma-related emergency room visits and hospitalizations. If those trends line up, it could provide some of the clearest evidence yet of what we already know: that electrifying transportation doesn't just clean the air on paper; it improves public health in practice.
