Rosberg reckons F1 is racing toward an electric future

Highlighting fresh concerns about global warming, Nico Rosberg foresees an eventual merger between the fuel-guzzling Formula One championship and the more environmentally friendly, electric Formula E series.

The German driver retired from F1 after winning his only title in 2016, and has since invested in the four-year-old Formula E championship, which he said is now worth $870 million.

While F1 remains more attractive to sponsors and fans, the upstart series is showing increasing commercial appeal.
