Two days ago, the U.S. Environmental Protection Agency issued a ruling that existing limits on tailpipe emissions of carbon dioxide for 2022 through 2025 should remain in place. The EPA's carbon limits correspond exactly to NHTSA standards for corporate average fuel economy, and the EPA decision was widely (if incorrectly) reported to be about... EPA keeps car-emission rules to 2025; what happens under Trump?

Even before the Volkswagen diesel scandal, diesel passenger cars were never popular in the U.S. But in other parts of the world—especially Europe—diesels have been the de facto choice of many buyers for decades. Increasing concern over air pollution and the VW scandal are beginning to change that, though. DON'T MISS: Paris weekday ban... 
The U.S. Environmental Protection Agency (EPA) has decided to maintain existing Corporate Average Fuel Economy (CAFE) standards through 2025. Enacted by the Obama Administration in 2012, the standards call for automakers to achieve a fleet average of 54.5 mpg (equivalent to about 38 mpg in the real world) by that year. The decision follows the... 
Stricter global emissions standards may finally force the majority of established automakers to get serious about electric cars. But while automakers build more electric cars to meet emissions standards, the extra cost of developing these new models may eat into profits. That's the conclusion of a new report from global investment bank Morgan... 
As the Volkswagen diesel scandal lumbers onwards, German media outlets have often broken the latest news and revelations from deep inside VW Group. While the German auto giant had hoped at first to have the issue largely wrapped up by now, the scandal first publicly revealed in September 2015 shows no signs of abating. The updates to... 
The combination of Tesla and SolarCity is already promoting its potential synergies, albeit in a location far away from the mainland United States. The island of Ta'u in American Samoa is located more than 4,000 miles from the U.S. West Coast, and typically relies on imported diesel fuel to generate electricity. With no local sources of fossil... 
Here's an electric vehicle that really, truly stinks. While automakers are moving in the direction of more electric cars, several companies are also making efforts to electrify commercial vehicles. The humble garbage truck will be the next to be electrified—which, if nothing else, will eliminate the unpleasant noise from huge diesel trucks... 
Fiat Chrysler Automobiles (FCA) and engine supplier Cummins are the latest companies to be accused of hiding excess diesel-exhaust emissions. A class-action lawsuit filed against the two companies Monday accuses them of conspiring to conceal illegally-high levels of emissions in Dodge Ram 2500 and 3500 diesel pickup trucks manufactured between... 
There's been considerable debate among advocates of battery-electric and hydrogen fuel-cell cars over which technology is better for the environment. While neither vehicle type produces any tailpipe emissions, their overall emissions vary depending on the fuels and processes used to generate electricity or produce hydrogen. A new study indicates... 
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...
