Electric cars may be all the rage, but for now, all but a tiny fraction of the 250 million vehicles on U.S. roads burn gasoline or diesel fuel. One of the ways that new vehicles are boosting fuel efficiency is the use of what are called "start-stop" systems, which switch off the engine while the car is stopped. Now, as the Department of Energy... Start-stop systems on U.S. light trucks doubled to one in five in a single year
Electric cars may be all the rage, but for now, all but a tiny fraction of the 250 million vehicles on U.S. roads burn gasoline or diesel fuel. One of the ways that new vehicles are boosting fuel efficiency is the use of what are called "start-stop" systems, which switch off the engine while the car is stopped.

The dominant news at the 2018 North American International Auto Show in Detroit was about pickup trucks. Ironically, the Detroit automaker with the fewest electrified models on sale was the only one to bring hybridization to a new truck, in the form of its brand-new 2019 Ram 1500. Fiat Chrysler Automobiles has lagged GM and FOrd on the... 
Public concerns over diesel cars, and their ebbing sales, have become a well-documented phenomenon in Europe after decades of popularity. When the VW diesel scandal exposed deliberate cheating, and real-world testing revealed that no virtually no diesels certified for sale actually met emission limits, automakers across the industry adopted rapid... 
OK, reporters of the world, it's time for a little chat. We know—believe me, we know—that you are cranking out a whole lot of copy, with much less support than you used to have, on far tighter deadlines, to feed a voracious, anonymous online audience whose clicks get you paid. But it's time to discuss the very, very important... 
Today's political climate has made for fluid motion in regulations, and corporate average fuel economy targets haven't been left out. Suppliers and automakers have already begun investing heavily into vehicles to be sold in 2022 through 2025, which will include various fuel-saving and emission-reducing technologies. However, that unsettled... 
Some are almost unnoticeable, others make the car shudder each time they activate—but start-stop systems are here to stay. First rolled out in Europe and Asia, where crowded city driving requires cars to spend more time at a standstill, they switch off the engine when the car's not moving. When the driver starts to lift a foot off the brake... 
Sometimes interesting predictions come buried inside a completely different topic. Take, for example, an investment note on the auto-parts supplier Continental contained in a roundup of industry research, market analysis, and news items issued yesterday by investment bank UBS. It contains the prediction that diesel engines' share of the global... 
Plug-in electric cars are slowly becoming more common, but internal-combustion engines will remain a significant presence on the world's roads for decades to come yet. That means automakers will continue trying to squeeze ever-greater efficiency out of these engines, making them more complex in the process. This will almost certainly include a...
