GM to invest $300m in Toyota and Daimler partner startups

General Motors will invest $300 million in Chinese autonomous driving startup Momenta to develop self-driving technologies for future models in China, its first such tie-up in the world's biggest car market.

The company is also backed by SAIC Motor, GM's leading Chinese partner, as well as Toyota Motor and Daimler AG.

Momenta is among the few companies that hold a permit for gathering high-definition maps in China, a key tool in autonomous driving technologies.
