Elon Musk is expected to announce details of Tesla’s robotaxi project Thursday, including a possible foray into self-driving semitrucks.

According to reports Wednesday, Tesla’s “We, Robot” event will kick off the electric vehicle company’s venture into robotaxis. Mr. Musk is expected to unveil the Cybercab and announce that Tesla’s Full Self-Driving technology will be coming to semitrucks.

The Cybercab is rumored to have butterfly-wing doors, two front seats and a steering wheel. Tesla plans to integrate the Cybercab with a ride-hailing app, which will let customers call the robotaxi like they would an Uber or Lyft.

The timeline for the robotaxi program hasn’t been made public, and industry experts expect Mr. Musk to provide details at Thursday’s event.

Tesla fans also expect the CEO to provide details of the company’s plans to let Tesla owners use their cars as robotaxis. In the past, Mr. Musk has implied that Tesla owners could rent out their cars on the ride-hailing app when not using them.

The “We, Robot” event is scheduled for 7 p.m. Pacific time at Warner Bros. Hollywood Studio in California.
