"Driving around with the windows up and the air conditioning or heat on is definitely the worst scenario, according to our computer simulations."

New liquid-fueled fuel cells outdo the voltage of conventional hydrogen fuel cells. Researchers call it a "game changer."

A new kind of concrete could let roads and bridges "heal" after cracking. That could cut down the costs and frequency of road repairs.

A new wireless charging technique could keep robots, drones, and, one day, potentially moving cars juiced up, researchers say.

Auto emissions are key to the creation of "ultrafine particles," which have been linked to health problems and birth defects, researchers say.

Smart cars are vulnerable to cybersecurity breaches, some of which could even be lethal. Companies need to catch up to protect consumers, researchers say.

Flash freezing car batteries offers a way to transport them in a safer, cheaper, and more environmentally friendly way, researchers say.

A better understanding of how catalytic converters break down could help pave the way for better versions that last longer and cost less to fix.

Since the rise of ride-sharing apps like Lyft and Uber, traffic accident deaths have gone up, new research finds.

"The misperception was that they would potentially fatigue faster and become a safety risk to other drivers.... I'm here to say that's just not true."
