Compression ratios At issue is the engines’ compression ratio, which compares the volume of the cylinder when the piston is at top dead center with the volume when the piston is at its closest to the crank. Under the 2014–2025 rules, this was set at 18:1, but for 2026 onward, it has been reduced to ..

When the traffic lights went out, Waymo’s robotaxis got a little too cautious at intersections. With no red-yellow-green to cue drivers, the rule is to treat the intersection as a four-way stop. Indeed, Waymo’s cars are programmed to do this, but it seems the scale of the outage over the weekend was just too much ..
At the heart of the car, between the axles, lives the 85 kWh lithium-ion battery pack, which gives the Equinox EV an EPA range of 319 miles (513 km) on a full charge. Unhelpfully, GM quotes charging as “up to 36 miles of range per hour of charging” for AC level 2 charging (at up ..
“The integration of Donut Lab’s revolutionary in-wheel motor technology represents a significant leap for what PACES can offer the automotive world,” said Neil Yates, CEO of WATT Electric Vehicles. “Its motors, inverter, and software systems, perfectly complement our lightweight platform philosophy. The direct, fine control of the individual wheel speeds brings an agility and that ..
SAN FRANCISCO—Automakers are starting to follow somewhat familiar paths as they continue their journeys to electrification. Electric vehicles are, at first, strange new tech, and usually look like it. Mercedes-Benz’s EQS and EQE are good examples—with bodies that look like bars of soap worn down in the shower, they stood out. For early adopters and ..
We learned then that Ford would keep the Kentucky plant and SK On gets the one in Tennessee, which would focus on the energy storage business instead. Now, we know that something similar will happen at the Kentucky plant—Ford says it’s spending $2 billion to convert the factory to make prismatic lithium iron phosphate (LFP) ..
Then there’s the temperatures. The desert gets quite chilly in November without the sun shining on things, and the track surface gets down to just 11° C (52° F); by contrast, at the recent Singapore GP, also at night, the track temperature was more like 36° C (97° F). It’s rare to see an F1 ..
“We learned how to be more efficient because before… we were so focused on performance that we almost forgot about efficiency, about it was full performance, and we have more people now than we had in 2017, for example, in the team, but we are spending less money,” Maia told me. Bigger data The number ..
Now it’s “Hey Google” not “OK Google” to trigger the assistant, which had started feeling a little left behind in terms of natural language processing and conversational AI to other OEM systems—sometimes even AAOS-based ones—that used solutions like those from Cerence running on their own private clouds. Gemini Going forward, “Hey Google” will fire up ..
Not everything about the future sucks. Like electric cars. Sure, there’s one thing that dinosaur-burners do better—short refueling stops—but even the least efficient EV is still multiple times better than its gas equivalent. So much better in fact that it offsets all the extra energy needed to make the battery within a year or two. ..
