African nations have a very specific problem when it comes to dealing with emissions from diesel vehicles. Because of lax emissions standards, traders import fuel to these countries that is too dirty for sale elsewhere. But now a handful of African nations are taking a stand against this.

African nations have a very specific problem when it comes to dealing with emissions from diesel vehicles. Because of lax emissions standards, traders import fuel to these countries that is too dirty for sale elsewhere. But now a handful of African nations are taking a stand against this.

From small startups to major established automakers, many companies have Tesla Motors in their sights. But Lucid Motors—the California-based startup formerly known as Atieva—may have the biggest guns in its arsenal of any of Tesla's would-be rivals. The company plans to unveil its previously-teased electric "executive sedan" December... 
Today, Donald Trump nominates a climate-science denier to head the Environmental Protection Agency (EPA), Congress questions $2 billion in zero-emission vehicle infrastructure funding from the Volkswagen diesel scandal, and a new study claims it is better to recycle electric-car battery packs than reuse them. All this and more on Green Car... 
The Volkswagen diesel settlement for 2.0-liter TDI models, approved at the end of October, includes a provision for $2 billion in funds to install charging or fueling infrastructure for zero-emission vehicles. There has been considerable debate over what those funds should be used for, and how they should be administered. The vast majority of the... 
Since it was launched in December 2010, the Nissan Leaf electric car has been offered with a telematics system that relies on a cellular connection. NissanConnectEV, previously known as Carwings, lets owners monitor functions like climate control and charging remotely, and find nearby charging stations. When the system launched, it was based on a... 
If there were any doubt that president-elect Donald Trump supports fossil fuels and does not believe in the scientific consensus of climate change, his pick to head the U.S. Environmental Protection Agency should put it to rest. Yesterday, he named Oklahoma attorney general Scott Pruitt, a 48-year-old Republican, as his nominee for EPA... 
Engineers are nothing if not creative. Significant research is going into improved ways of storing electricity, including alternatives to the currently dominant lithium-ion battery-cell chemistry in electric cars. That includes using supercapacitors to substitute for storage batteries in some circumstances. DON'T MISS: Batteries from junkyard... 
Last week, we wrote about the results of a Twitter poll we put up to get a feel for what our readers like best about the site. The flipside of "most valuable" is "least valuable," so we put up the same list of choices again, this time asking survey respondents to rank their least favorite types of articles. Surprisingly, however, the results... 
Even after they have degraded too much for continued automotive use, the lithium-ion battery packs in electric cars still have significant useful storage capacity. That's led several automakers to experiment with alternative uses for these "second-life" batteries in stationary energy storage. Battery packs can store energy generated by renewable...
