A top General Motors official is taking on a new role that underlines the auto industry’s intense push to develop and commercialize self-driving cars.
The official, Dan Ammann, will give up the job of G.M. president and become chief executive of Cruise, the division working on autonomous vehicles, the company said Thursday.
The move gives Cruise increased management heft as it prepares to start a driverless-ride service by the end of 2019. G.M. expects the service and other related businesses to expand rapidly, and Mr. Ammann said it could involve “trillions” of self-driving cars in the future.
