US carmaker General Motors Co is scaling up its investment in electric cars and autonomous driving from 2020 through 2025 to $35 billion, which is around 30 percent up from its previous budget of 27 billion.

"We are investing aggressively in a comprehensive and highly-integrated plan to make sure that GM leads in all aspects of the transformation to a more sustainable future," said GM Chair and CEO Mary Barra.

"GM is targeting annual global electric car sales of more than 1 million by 2025, and we are increasing our investment to scale faster because we see momentum building in the United States for electrification, along with customer demand for our product portfolio," she said.

The carmaker unveiled its vision of a world with zero crashes, zero emissions and zero congestion nearly four years ago. It said the additional investment will create greater competitive edges.
