Lyft to test self-driving robot cars at Concord’s GoMentum Station.

Lyft will put robot cars through their paces at Concord’s GoMentum Station, a 5,000-acre autonomous-vehicle testing facility, the ride-hailing company said Thursday.

“By partnering with GoMentum Station, we’re able to test our self-driving systems in a secure facility and advance our technology in an efficient way,” said Luc Vincent, Lyft’s vice president of engineering.

GoMentum Station, formerly the Concord Naval Weapons Station, has miles of paved roads winding through scrubby terrain, all secured by fences and locked gates.

While California requires backup drivers for robot cars on public roads (although soon it will allow testing without humans at the wheel), as a private facility, GoMentum has no such restrictions. Other companies testing autonomous vehicles at GoMentum include China’s Baidu, Honda, Uber and France’s EasyMile.

Another former military facility, Castle Air Force Base near Atwater (Merced County), also offers its miles of private roads for autonomous vehicle testing. Waymo, an offshoot of Google parent Alphabet, has leased 91 acres of Castle to test its self-driving Chrysler Pacifica minivans.

Lyft last year started its own self-driving division in Palo Alto, called Lyft Level 5 Engineering Center, a reference to the industry designation for fully self-driving cars. The company said it expects to have several hundred engineers there by the end of this year.

Lyft also has robot-car partnerships with several other companies, including NuTonomy in Boston, where it is testing autonomous taxi rides with backup drivers and Jaguar Land Rover, which said it will place its future autonomous cars into service with Lyft. Lyft and Mountain View’s Drive.ai said in September that they will bring a self-driving ridehailing service to the Bay Area, but they have not set a date.

General Motors invested $500 million for a 9 percent stake in Lyft two years ago and had said it would provide Lyft with self-driving cars for its on-demand rides. However, GM, whose Cruise division in San Francisco is rapidly developing new generations of autonomous cars, has been mum about its Lyft relationship for the past year.
