IEEE Spectrum’s transportation protection this yr coated breakthroughs in electrical autos, batteries, charging, automation, aviation, maritime tech and extra. Readers adopted the race to rebuild U.S. magnet manufacturing, rethink EV-charging structure, and reinvent automotive software program. They tracked China’s dash towards five-minute charging, the rise of high-power house chargers, and the push to automate airports. Our most-read tales additionally explored next-generation navigation, zero-carbon delivery fuels, record-size electrical vessels, and early street exams of solid-state batteries. Learn on for our roundup of the transportation tales revealed in 2025 that readers discovered most compelling.

The most-visited transportation publish of the yr targeted on america’s efforts to rebuild a home provide of neodymium-iron-boron (NdFeB) magnets—important elements for EVs, wind generators, HVAC techniques, and plenty of army techniques. MP Supplies has begun trial manufacturing at its new Texas plant, with plans to ramp as much as between 1,000 and three,000 tonnes per yr and provide firms like Basic Motors. Different U.S. tasks from e-VAC Magnetics, Noveon, USA Uncommon Earth, and Quadrant are additionally rising.
However these efforts are dwarfed by China’s uncommon earths trade: China makes 85 to 90 p.c of NdFeB magnets and 97 p.c of the underlying uncommon earth metals, with particular person Chinese language companies producing tens of hundreds of tonnes—way over all non-Chinese language crops mixed. China additionally has huge unused refinement and manufacturing capability, protecting world costs low.
MP Supplies’ distinctive mine-to-magnet technique may provide intelligence and supply-chain resilience, however competing with China’s subsidies and scale will likely be extraordinarily tough. The U.S. Division of Protection might pay a premium for “friendly-nation” magnets, however cost-obsessed automakers like GM would possibly resist increased home costs.

A powerful public EV-charging community is crucial for mass electric-vehicle adoption, particularly for drivers who can’t reliably cost at house. But at the moment’s fast-charging stations are costly and complicated largely due to one function: galvanic isolation—the transformer-based security barrier that protects towards electrical shock when floor connections fail. This isolation {hardware} accounts for roughly 60 p.c of charger power-electronics price and about half of energy losses, making quick chargers expensive to construct and keep. The authors of this piece—veterans of AC Propulsion, whose early expertise influenced the Tesla Roadster—argue that galvanic isolation is now not crucial.
The authors suggest a brand new method they name direct energy conversion (DPC): get rid of the isolation hyperlink totally and substitute it with: (1) a double-ground system with ground-continuity detection to forestall shock hazards, and (2) a buck regulator to deal with voltage mismatches between the grid and the EV battery. Eradicating isolation would simplify chargers from 4 power-conversion levels to only one (plus a buck regulator if wanted). This might reduce charger {hardware} prices by greater than half, enhance effectivity by 2–3percent, allow less expensive fast-charging stations, permit EV onboard chargers to develop into highly effective sufficient for Stage 3 charging, and speed up enlargement of public charging infrastructure.The authors argue that simplifying chargers—and shedding previous assumptions about galvanic isolation—is the quickest path to an reasonably priced and dependable EV-charging community, which is important to broad EV adoption.
BYD has unleashed megawatt-class EV charging in China, delivering 400 kilometers of vary in 5 minutes—triple the facility (and thus triple the velocity) of at the moment’s finest U.S. setups. A Han L sedan briefly hit 1,002 kilowatts on BYD’s new 1,000-volt platform, which makes use of 1,500-V silicon-carbide chips and redesigned lithium iron phosphate batteries to allow secure, ultrafast charging. BYD’s vertically built-in method—constructing automobiles, batteries, and chargers—lets it scale rapidly and preserve costs low. The corporate has already deployed 500 megachargers and plans 4,000 extra, pushing China far forward as rivals like Huawei and Zeekr race to match speeds as much as 1,500 kW.China makes 85 to 90 p.c of NdFeB magnets and 97 p.c of the underlying uncommon earth metals, with particular person Chinese language companies producing tens of hundreds of tonnes—way over all non-Chinese language crops mixed.

Whereas BYD is amping up public EV charging speeds in order that including vary takes now not than filling a petroleum automobile’s gas tank, one other firm is pursuing a charging technique that makes higher use of the time when autos sit idle—which is more often than not.

Airports are rolling out a wave of latest automation to hurry journeys from curb to gate. Copenhagen Optimization’s Digital Queuing lets vacationers reserve safety occasions, with machine-learning fashions adjusting slots and staffing in actual time. Digital Bagtags generate paperless baggage tags through NFC, whereas Idemia’s biometric techniques confirm id with a fast face scan. Smiths Detection’s X-ray diffraction machines establish supplies by molecular “fingerprint,” decreasing false alarms. Amazon’s Simply Stroll Out outlets allow cashierless purchases, and Avidbots’ Neo robots autonomously scrub terminal flooring. Even boarding will get smarter with techniques that flag passengers attempting to leap the queue.Eradicating galvanic isolation may simplify chargers from 4 power-conversion levels to only one. This might reduce charger {hardware} prices by greater than half, enhance effectivity by 2–3percent, and allow less expensive fast-charging stations.
