China is known for having some of the most polluted air in the world. But officials in one Chinese city found a way to at least make that air appear cleaner, for awhile. Like many Chinese cities, Xi'an, the provincial capital of Shaanxi, in the northern part of the country, has air-monitoring equipment. DON'T MISS: Coal in China: huge problem for...

Are you driving a car or a truck? The answer may be harder to determine than you think. U.S. safety and emissions regulations generally split cars and trucks into two categories, but the line between those two vehicle types has become blurred in recent years. That's thanks to the car-based crossover utility vehicle, which now represents one of the... 
The rise of electric cars has led many analysts to make predictions about the future of the oil industry. ExxonMobil and OPEC have both made statements indicating confidence that the majority of vehicles on the world's roads will continue to be powered by fossil fuels for the next few decades. But Shell recently made a prediction that is a bit... 
Faraday Future plans to put an electric car into production within two years at a brand-new factory with a stated price tag of $1 billion. So far, this ambitious plan has had the backing of Chinese billionaire Jia Yueting, and his LeEco tech empire. But now LeEco may be running out of cash. DON'T MISS: Faraday Future imperils electric-car factory...

Over the past few years, China has made impressive strides in renewable-energy investment. The promotion of renewable energy will only become more important as China works to meet its commitments under the recently-ratified Paris climate agreement. But the country's reliance on coal for electricity generation still poses a huge problem for these... ![Tesla Model S at Supercharger site in Ventura, CA, with just one slot open [photo: David Noland]](http://images.hgmsites.net/tmb/tesla-model-s-electric-car-road-trip-upstate-new-york-to-southern-california-photo-david-noland_100500011_t.gif)
A major perk for Tesla Model S and Model X owners has been free access to the carmaker's network of Supercharger DC fast-charging stations. But after January 1, new Tesla buyers won't get that free access. Tesla will charge anyone who buys one of its cars after that point for use of Supercharger stations, a move it says is meant to emphasize use... 
The Volkswagen diesel scandal convinced European regulators to switch from laboratory emissions testing to tests that involve actual, on-road driving. This could prevent automakers from deploying "defeat device" software like the kind used by VW on laboratory tests, as well as produce results that more closely align with what consumers can expect... 
Toyota has been a confirmed naysayer on long-range battery-electric cars for two decades. Instead, hydrogen fuel cells have been its zero-emission technology of choice. In that context, a new report suggesting Toyota will start building significant numbers of battery-electric cars is quite stunning indeed. DON'T MISS: Now Toyota can make electric... 
While Volkswagen has received approval from U.S. and European authorities to take some steps to address diesel cars with emissions-cheating "defeat device" software, the diesel scandal is still expanding. A German probe into whether VW should have notified investors of the "defeat devices" earlier now includes the chairman of the company's...
