SILVER SPRING, Md. (AP) — General Motors is teaming up with Microsoft to accelerate its rollout of electric, self-driving cars. In the announcement Tuesday, the companies said Microsoft’s Azure cloud and edge computing platform would be used to “commercialize its unique autonomous vehicle solutions at scale.”

Microsoft joins General Motors, Honda and other institutional investors in a combined new equity investment of more than $2 billion in Cruise, bringing its valuation to about $30 billion.

Cruise, which GM bought in 2016, has been testing its automated vehicles in San Francisco without backup drivers. Shares in GM jumped more than 8% Tuesday morning.
