DETROIT (Reuters) - Faraday Future plans to begin testing prototype self-driving electric vehicles on California roads later this year after winning approval from the state, an industry source said on Tuesday.

The China-backed, Los Angeles-based startup plans to begin building and selling electric vehicles next year in the United States, but has not disclosed details of its self-driving program.

A spokesperson from the California Department of Motor Vehicles on Tuesday confirmed that Faraday had been approved to test self-driving vehicles on public roads on June 17.

Faraday is one of several Chinese-funded startups hoping to challenge Tesla Motors Inc in premium electric vehicles.

Like Tesla, Faraday also hopes to add self-driving capability to its vehicles, but has not provided a timetable. Faraday has been testing prototype vehicles for the past year at private facilities, according to the source familiar with the company’s program.

Jan Becker, senior director of automated driving at Faraday’s San Jose tech center, said in an early June interview with Reuters that the company’s electric vehicles would have “state of the art driver assistance systems.” Such systems provide the foundation for full self-driving capability.

Becker declined to give specifics on the company’s plans to add self-driving capability, but said such systems, when introduced, would offer automatic over-the-air software updates similar to those provided by Tesla.

California previously approved 13 companies to test autonomous vehicles on public roads, most recently two Silicon Valley startups, Zoox and Drive.ai, funded by venture investors. The state’s Department of Motor Vehicles also has approved testing by Cruise Automation, which was acquired earlier this year by General Motors Co.

Other approved testers include Alphabet Inc's Google, Tesla, Volkswagen AG VOWG_p.DE, Daimler AG's Mercedes-Benz, Nissan Motor Co, BMW AG, Honda Motor Co and Ford Motor Co, and auto suppliers Robert Bosch [ROBG.UL] and Delphi Automotive.
