Formula E races to keep pace with EV technology

Formula E now has its highest number of automaker teams to date with Porsche and Mercedes-Benz joining Nissan, Jaguar, Audi, BMW, DS, Nio and Mahindra in the motorsport championship that uses only battery-powered cars.

Automakers are attracted to the series, whose sixth season began Friday and runs until July 26, because it’s a relatively cost-efficient way of marketing electric cars to viewers who mainly watch to see big-name drivers racing closely on tight street circuits.
