Electric car competition heats up at Shanghai auto show.

Global and Chinese automakers are set to unveil over a dozen new electric SUVs, sedans, and muscle cars at the Shanghai auto show, their first full-scale sales event in four years in a market that has become a workshop for developing electrics, self-driving cars, and other technology. Established global brands face intense competition from Chinese rivals, who have invested billions of dollars in subsidies to buy an early lead in an emerging industry. The ruling Communist Party is winding down government support and shifting the burden to automakers by requiring them to earn credits for EV sales.
