A prominent lobbying group believes environmental remediation funds from Volkswagen diesel settlements should be spent on new "clean" diesel vehicles. The settlement for 2.0-liter TDI cars approved last year requires VW to pay $2.7 billion into a trust, managed by a third party. Volkswagen agreed...

Donald Trump won the U.S. Electoral College and swept into the White House on a varied platform that included significant promises to cut regulation and reduce government involvement in a wide variety of spheres. The day after his election, the Alliance of Automobile Manufacturers sent him a letter...

What if gasoline and diesel cars and light trucks were simply eliminated altogether from the new vehicles sold in a state? Residents of one state in the U.S. may, eventually, find out. California already leads the nation in promoting zero-emission vehicles, but the Golden State may soon take that...

Statements from the boards of directors of automakers are generally dry, dispassionate, and formal. So the language of a terse item issued yesterday by the board of Volkswagen Group was remarkable in its directness. Not to mention its inferences about the company's former CEO Ferdinand Piech, who...

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...

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...

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...

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...

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...

As seemed likely from the day Donald Trump was elected president of the United States, the country will pull out of the global Paris Climate Agreement to reduce greenhouse-gas emissions. The move had been signaled even before the election by the new president's choice of noted climate-science...

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...

Yesterday, analyses of the air in several parts of France showed it 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...

The new U.S. administration has made it clear that it does not accept the scientific consensus on climate change. From President Donald Trump down through his nominees for key roles—Scott Pruitt for EPA adminstrator, Rick Perry for Department of Energy head, and others—key elected and...

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...

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...

Transitions into new technologies always generate confusion and misinformation, and certainly that has been the case with modern electric cars. Buyers, automakers, and analysts debate their cost, suitability, real-world range, wells-to-wheels carbon footprint, and recyclability, among other issues...

Despite scientists having reached a consensus years ago, considerable debate still appears to be raging over the reality of climate change. Climate-science deniers can count several people appointed to key environmental-regulatory positions in the incoming presidential administration among their...

With auto-industry lobbyists pushing to have the Trump Administration roll back current and future emission and fuel-economy rules, automakers clearly see the new U.S. regime as more friendly to the needs of business. And it's possible that indeed, the EPA's vehicle emission limits, the NHTSA's...

The past week has not been a particularly pleasant one for advocates of diesel cars. Volkswagen agreed to plead guilty to criminal counts related to its diesel-emissions cheating and pay $4.3 billion in fines, while U.S. prosecutors arrested one of the company's executives and indicted five more...

It's been a busy week for U.S. agencies as they release information on their final actions before a new administration takes office. Yesterday the U.S. Department of Justice reportedly opened a criminal probe into the actions of Fiat Chrysler Automobiles over the emission certification of its...
