At Tech Day, China’s version of GM’s EV Day, GM has announced major advancements coming to its vehicles in China.

China is GM’s largest market. As a result, the company took the opportunity to outline major initiatives that it plans to bring to fruition in the Chinese market.

Among those advancements is 5G connectivity, which the company plans to implement in 2022. GM plans to have all Cadillac and most Chevrolet and Buick models connected by then, with connected services provided via over-the-air updates.

GM also plans for 40% of its new vehicle launches in China to be electrified models within the next five years. The company has already vowed to invest more than $20 billion in electric and automated vehicles by 2025. GM plans on bringing together 5G, AI, big data and smart cities to help make its plans a reality.

“As GM’s largest market and a global center of innovation, China will play a crucial role in making our vision a reality,” said Mary Barra, chairman and CEO of GM. “With our joint venture partner SAIC, we are blending global insights and scale with local market expertise to redefine what is possible for our customers and for society.”
