Last month, the U.S. Environmental Protection Agency proposed a historic set of vehicle tailpipe emissions standards, aimed at making two-thirds of all passenger cars zero-emissions by 2032, along with 46 percent of medium-duty trucks (such as delivery vans) and 25 percent of heavy-duty trucks such as 18-wheelers. The proposed standards, which would phase in over… Continue reading Electrifying Standards: U.S. Joins EV Race to Zero

Little Robots Learn to Drive Fast in the Real World
Without a lifetime of experience to build on like humans have (and totally take for granted), robots that want to learn a new skill often have to start from scratch. Reinforcement learning is a technique that lets robots learn new skills through trial and error, but especially in the case of learning end-to-end vision based… Continue reading Little Robots Learn to Drive Fast in the Real World
“Liquid” Neural Network Adapts on the Go
In the realm of artificial intelligence, bigger is supposed to be better. Neural networks with billions of parameters power everyday AI-based tools like ChatGPT and Dall-E, and each new large language model (LLM) edges out its predecessors in size and complexity. Meanwhile, at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), a group of researchers… Continue reading “Liquid” Neural Network Adapts on the Go
Hyundai Making (Tesla) Killer EVs on the QT
In the booming business of electric cars, you expect innovation and ingenious features to hail from luxury land: Lucid, Rivian, Porsche, or Tesla. Driving the new Hyundai Ioniq 6 sedan highlights the rise of an underdog that was almost wholly unforeseen: South Korea’s Hyundai Motors, and its Kia and luxury Genesis brands, are cranking out… Continue reading Hyundai Making (Tesla) Killer EVs on the QT
Modeling Electric Motors and Drivetrains
There has been an exponential increase in the demand for electric vehicles, with hybrid and electric cars expected to account for a considerable portion of car sales in the near future. Designing efficient motors is critical for increasing range, reducing battery capacity requirements, and improving power density and costs. Register now to attend this free… Continue reading Modeling Electric Motors and Drivetrains
Automotive Radar Object Simulation for Validation
This is a sponsored article brought to you by Rohde & Schwarz. Homologation and validation of new vehicle models today require millions of test kilometers to be driven under different environmental conditions, on different types of roads in various countries around the world. Due to the increased complexity of automated driving (AD) and advanced driver-assistance… Continue reading Automotive Radar Object Simulation for Validation
Fast Food, Fast Charge
It sounds so obvious: Public EV chargers should be located in public, where people tend to gather. The reality has often been otherwise, with too many chargers tucked into desolate parking lots or seemingly random locations. And since even the speediest DC chargers take roughly 30 minutes to juice up an EV, drivers and passengers… Continue reading Fast Food, Fast Charge
Aviation, the Unlikely Road to Long-Range EVs
Of all the elements in the periodic table, silicon has the highest capacity for combining with lithium. It can hold ten times more lithium ions than the graphite anodes common in today’s lithium-ion batteries. Several carmakers and battery startups are looking at silicon anodes for the next generation of long-range, lightweight EV batteries. And now… Continue reading Aviation, the Unlikely Road to Long-Range EVs
The Staggering Scale of the EV Transition
Over the last 20 or so years, contributing editor Robert N. “Bob” Charette has written about some of the thorniest issues facing the planet at large and engineers in particular. For IEEE Spectrum, he’s dug into software reliability and maintenance, the so-called STEM crisis, and the automation paradox, examining those complex topics through the eyes… Continue reading The Staggering Scale of the EV Transition
Lightning Eyes 10-Minute Charging for Its Motorbikes
Lightning Motorcycles is already known for record-setting speeds. In 2011, the company’s LS-218 SuperBike set a land speed record for production electric motorcycles at the Bonneville Salt Flats in Utah, with a 347.55 kilometer-per-hour (215.91 mile-per-hour) average run and a 351 km/h (218 mph) peak. That SuperBike topped every internal combustion engine motorcycle en route… Continue reading Lightning Eyes 10-Minute Charging for Its Motorbikes
