GM to invest $100 million to upgrade facilities to build self-driving cars

WASHINGTON, March 15 (Reuters) - General Motors Co said Thursday it will invest more than $100 million in two facilities as it prepares to build production versions of its Cruise self-driving car next year at its Orion Township assembly plant in Michigan.

The largest U.S. automaker also said roof modules for GMs self-driving vehicles will be assembled at its Brownstown Battery Assembly plant.

In January, GM filed a petition seeking U.S. government approval for a fully autonomous car - one without a steering wheel, brake pedal or accelerator pedal - to enter the automakers first commercial ride-sharing fleet in 2019. (Reporting by David Shepardson Editing by Nick Zieminski)
