If you're a diehard diesel fan, you now have one last chance to buy a brand-new Volkswagen TDI diesel car. Well, almost brand-new, anyhow: the cars in question are 2015 models, and about 11,000 of them will go on sale after they have been modified. Once they're sold, there will likely be no more...

Despite efforts by Chevrolet to step into the void left by Volkswagen, sales of diesel passenger vehicles in the U.S. may have been permanently crippled by the VW diesel emission scandal. In Europe, however, diesel has been entrenched for decades as roughly 50 percent of the market. Even before the...

Seattle-based startup Zunum Aero has received funding from Boeing HorizonX and JetBlue Technology Ventures toward making its dream of electrified air travel a reality. Sometimes billed as the Tesla of the airplane industry, Zunum is developing a relatively small regional aircraft with about 700...

Despite some alarmist reporting, President Donald Trump hasn't abolished the EPA's vehicle emission limits. Nor has he wiped out corporate average fuel-economy rules, set by the NHTSA. So far, he's done two things: signed an executive order reopening the comment period for 2022-2025 EPA emission...

The Clean Power Plan’s future looks uncertain at best under President Donald Trump. The commander-in-chief appears to be urging American utility companies to pivot back towards burning coal to produce electricity. Ending the so-called “war on coal” is intended to create jobs in...

If you have your eyes on a used Volkswagen or Audi TDI turbodiesel, you may wind up having to pay more today for 2009 through 2015 models than you would have when they were new. At least right now, only 2015 model-year versions of VW and Audi vehicles sold with the 2.0-liter turbodiesel 4-cylinder...

The prospect of ongoing operations as usual continues to darken for the Environmental Protection Agency. According to a detailed internal budget document published in the The Washington Post, the Trump administration wants to eliminate virtually all federal funding for the agency’s vehicle...

The new U.S. president, Donald Trump, is working to eradicate every Obama policy to limit the carbon emissions that contribute to climate change.

For more than 13 years, London has collected a stiff charge from motor vehicles entering the congested core of the city during weekday business hours. Known as the congestion charge, the fee of £11.50 a day, or $14.50 (£10 with automatic payment, or $12.50) is levied from 6 am to 7 pm...

No vehicle on earth is entirely free of emissions; even electric cars charged on renewable energy have emissions associated with their manufacturing. Those emissions, however, are a tiny fraction of the carbon dioxide and other substances emitted by gasoline or diesel cars when scientifically...

Natural gas is growing as a part of the world's grid mix, because its carbon per kilowatt-hour is much lower. But methane leaks that emit large volumes of climate-change gas into the air may offset that advantage. Now, a Google Street View car has allowed researchers to pinpoint and quantify the...

Given the current political landscape in Washington, it's not unreasonable to worry about the future of U.S. efforts to combat climate change. The Trump Administration has embarked on an explicit mission to undo all Obama Administration efforts to reduce carbon emissions. Climate-science deniers in...

While renewable energy gets significant press as an alternative to coal in electricity generation, it isn't the main factor in decreasing the use of that carbon-intensive fuel. Thanks to its generally lower cost, natural gas is quickly displacing other fuels in the nation's power plants. In...

The California Air Resources Board voted Friday to confirm its stricter emissions standards for 2025, setting up a potential clash with the Trump Administration. The CARB vote reaffirms a decision by the EPA in the waning days of the Obama Administration to lock in emissions standards for vehicles...

While political control in Washington has changed, the debate over a mandate to blend specific volumes of ethanol into the U.S. fuel supply has not. Since its passage in 2007 as part of the Energy Independence and Security Act, the ethanol-mandating Renewable Fuel Standard has attracted...

The auto industry tends to oppose, viscerally and viciously, all attempts to regulate any aspect of its products or business operations for any reason. With President Trump in the White House, the industry has succeeded in getting the comment period reopened for the EPA emission standards finalized...

At the 2017 Geneva auto show, General Motors announced the sale of its entire European operations—comprising factories and the Opel and Vauxhall brands—to PSA Peugeot Citroën. German Opel and its British Vauxhall sibling have represented GM's main presence in Europe for decades...

It crops up in comments from electric-car advocates and clean-energy users fairly regularly. And it goes something like this: "Big Oil and Gas are on the verge of collapse, as clean energy and electric cars make them obsolete." Occasionally the sentiment is followed by an approving emoji. DON'T...

Fiat Chrysler Automobiles continues to be dogged by allegations that it cheated on various diesel-emissions tests. In the U.S., the company faces two lawsuits alleging that diesel vehicles use "defeat device" software to circumvent emissions tests in a similar manner to Volkswagen's cheating TDI...

As it tries to put the ongoing diesel-emissions scandal behind it, VW Group is focusing its future on electric cars. The Volkswagen brand within the sprawling German company has developed an electric-car specific platform called MEB, and has shown multiple concepts based on it. Those include the ID...
