Southwest Research Institute (SwRI) has upgraded its hydrogen-powered heavy-duty internal combustion engine (H2-ICE) with a state-of-the-art turbocharger. The upgrades have significantly improved performance across the board, making the engine competitive with current long-haul diesel engines focused on fuel economy while maintaining near-zero tailpipe emissions....

The next time you board a commercial flight and are told how to sit in the brace position for an emergency landing, consider this: did you know that international plane safety testing only requires adult male crash test dummies?... Read more

As America's aging roads fall further behind on much-needed repairs, cities and states are turning to artificial intelligence to spot the worst hazards and decide which fixes should come first.... Read more

More expensive cars emit lower levels of pollution—meaning that motorists owning cheaper, higher-emitting vehicles contribute disproportionately to their local urban air quality problems, a new study reveals.... Read more

A research team affiliated with UNIST has introduced a gel-like material that could extend the lifespan and enhance the safety of high-voltage electric vehicle (EV) batteries designed for long-distance driving.... Read more

Waymo is hitting the highway. The company said starting Wednesday its robotaxis—already a common sight on some city streets—are expanding their routes to freeways and interstates around San Francisco, Los Angeles and Phoenix. And in the Bay Area, riders can now get dropped off or picked up curbside in driverless... Read more

Aviation currently contributes about 2.5% of total global carbon emissions, and with air travel demand expected to double by 2040, cutting those emissions has become a pressing priority. One path forward is sustainable aviation fuel, a low-carbon alternative made from feedstocks such as used cooking oil and crops. But despite... Read more

Major Western ride-hailing platforms like Uber and Lyft sketched a gradual path toward introducing self-driving cars at this week's Web Summit in Lisbon, with infrastructure, developing regulation and passengers' preference for human contact weighing on the brakes.... Read more

Picture an electric car that could go 600, 700 or even 1,000 miles on a single charge. That's much farther than the longest-range electric vehicles on the U.S. market, according to Car and Driver magazine—and twice as far the official rating for the long-range, rear-wheel-drive Tesla Model 3, which has...

Southwest Research Institute (SwRI) has developed a method to automate the calibration of heavy-duty diesel truck emissions control systems using machine learning and algorithm-based optimization. The latest diesel aftertreatment systems often take weeks to calibrate. SwRI's new method can calibrate them in as little as two hours.... Read more

Hypersonic planes could fly from Sydney to Los Angeles in just an hour. What's standing in the way of such ultra-fast planes becoming reality is our understanding of how the turbulence they generate as they fly at such high speeds impacts their design. Now, a new study suggests that building... Read more

A research team has developed an extrapolation-based Doppler resolution enhancement algorithm for frequency modulated continuous wave radars. The algorithm improves system performance, offering an advancement that is superior to existing ultra-high-resolution technologies.... Read more

Autonomous vehicles (AVs) have been tested as taxis for decades in San Francisco, Pittsburgh and around the world, and trucking companies have enormous incentives to adopt them.... Read more

The Société de transport de Montréal (STM), the city's urban transit authority, plans to make its network completely electric by 2040 by adding 140 electric buses to its fleet annually to meet this target. It's an ambitious goal, made more challenging by the extreme swings in the city's weather every... Read more

Car enthusiasts will pay hundreds of dollars for stereo systems that will improve the sound quality in their cars. However, the inherent directionality of speakers and complex shapes of car cabins can exacerbate sound disparities between the drivers and passengers, no matter how advanced a speaker system....
