There’s electricity in the air at the China auto show in Shanghai this week, as the battery-car brigade rolls into town like never before.
Established global makers and dozens of local startups are rushing to showcase electric-vehicle models in a push led by China, the world's largest car market. But there’s a dark side: While companies have plowed billions of dollars into development, projected EV sales may not be enough to keep the assembly lines moving, suggesting only a few companies will survive when the dust settles.
Here are some of the sleekest, most technologically advanced models on display at the Shanghai showcase.
