As automakers develop more efficient electric motors, EVs pulling electrons from dirtier, coal-powered grids are as clean or cleaner than even the most efficient fossil-fueled cars when it comes to equivalent tailpipe emissions. But electric vehicles still have a supply-chain problem. A partnership between some of the world's largest automakers is... Ethical sourcing for electric-car minerals: Toyota, Honda, VW, Ford, others sign pledge

It's not surprising that the powertrains of electric cars differ quite a bit from traditional internal-combustion engines. Although they have fewer moving parts, the rare-earth magnets that help power electric cars can be quite complex to fabricate. So, what is there to know about rare-earth magnets—and how do automakers choose which kind of... 
One of several new electric cars and concepts at last week's Paris Motor Show was the electric version of the second-generation Smart minicar. As Smart pointed out, it's the only maker that offers the option of gasoline or electric powertrains in every model it makes. Those are the ForTwo two-seat coupe, the ForTwo cabriolet with its roll-back...
