Mercedes-Benz is accelerating its rollout of battery-powered autos in a race to meet tighter emissions rules as European buyers turn away from fuel-efficient diesel cars.
 
 In a 10 billion-euro ($10.8 billion) project, the world’s largest luxury-car maker intends to release 10 new electric vehicles by 2022, three years earlier than a target announced at the Paris auto show in September. The expedited time frame reflects the urgency facing manufacturers as they brace for a shift away from traditional automotive technologies. Combustion engines would continue to be refined for a “transitional period,” Mercedes parent Daimler AG said on Wednesday.
