When it comes to improving fuel efficiency, simply making an engine smaller is a fairly direct way to get results. It's the approach that many automakers have taken in recent years. They have downsized engines across model lines, usually adding turbochargers at the same time to match the power output of the larger-displacement engines that they... VW suggests engine downsizing is done; emissions rules are the reason
When it comes to improving fuel efficiency, simply making an engine smaller is a fairly direct way to get results. It's the approach that many automakers have taken in recent years. They have downsized engines across model lines, usually adding turbochargers at the same time to match the power output of the larger-displacement engines that they... 
With a judge set to weigh in on the settlement VW Group negotiated with its 3.0-liter V-6 diesel owners, Volkswagen seems to have settled most of the U.S. legal claims stemming from its diesel-emission cheating scandal. Total costs in the U.S. alone are now more than $20 billion, and among other penalties, VW has pleaded guilty to three felony... 
Volkswagen today announced that it had reached a settlement with owners of Audi, Porsche, and VW vehicles fitted with its 3.0-liter V-6 diesel engine. Different remedies apply depending on the vehicle's model year: 2009 through 2012 cars will be bought back, while 2013 through 2016 vehicles will be modified to comply with emission limits. The... 
Among his actions during a whirlwind first week in office, U.S. President Donald Trump met last week with the CEOs of U.S. automakers Fiat Chrysler, Ford, and General Motors. He met on two consecutive days with Mark Fields, CEO of Ford, in fact. Fields was part of a group of manufacturing executives who met with the president separately the day... 
The Volkswagen diesel scandal has led to much greater scrutiny on the methods regulatory agencies use to test vehicle emissions, particularly in Europe. Even before news of Volkswagen's diesel "defeat device" software broke, the European fuel-economy testing cycle was known to be overly optimistic, producing results that buyers could not replicate... 
What would you do if a small, knee-high box on wheels with a flag topping its tall antenna whirred toward you electrically on a sidewalk at 4 miles per hour? It turns out three-quarters of the pedestrians in several cities who've seen one didn't stop or even stare as it avoided them and continued on its way. That box is an electric sidewalk... 
Sergio Marchionne, CEO of Fiat Chrysler Automobiles, believes diesels will allow the company to meet future, tougher fuel-economy standards. But that faith is being sorely tested at the moment. The U.S. Environmental Protection Agency (EPA) now says the company failed to disclose software for its EcoDiesel 3.0-liter V-6 engine that could affect... 
Yesterday, analyses of the air in several parts of France contained high levels of ultrafine particles emitted by road vehicles. Among the guiltiest culprits were older diesel vehicles with minimal emission-control systems, particularly those built under the Euro 4 standard in effect through 2005. Over the last year, Paris has instituted... 
During negotiations for the Paris Climate Treaty signed last fall, a major concern among critics was whether the carbon emissions of China's sprawling and inefficient energy sector could be reined in. With China, the U.S., and dozens of other countries signing the agreement, the world's most populous country committed itself to decarbonizing its... 
For electric utilities eager to hang onto their existing coal-fired power plants, carbon-capture technology must offer an exciting chance at salvation. As the name says, carbon capture retains and stores the emissions produced by coal power plants in particular, in theory mitigating some of their environmental impact. Power plants equipped with...
