SAN FRANCISCO — Cruise, the autonomous vehicle division of General Motors, unveiled an ambitious new vehicle on Tuesday that its executives said was “the beginning of the future beyond the car.”

Emphasis on “beginning.”

The futuristic electric vehicle, the Cruise Origin, has a long road to travel before any passengers will be able to hail a ride in it. Cruise would not name a time frame for its availability. It provided no details on how many vehicles it planned to produce, or whether it has begun test drives on closed tracks. It has not obtained state or federal regulatory approval to drive on roads.

“Our work is far from done,” Dan Ammann, chief executive of Cruise, said during a presentation in San Francisco.

Cruise emphasized that the Origin was more than just an idea, however. In an interview, Mr. Ammann said the company would begin producing prototypes of the Origin and test driving the car “in the near future.”
