Plus (formerly Plus.ai) has added $220 million in new financing co-led by FountainVest Partners and ClearVue Partners, with participation from Quanta Computer Inc., Phi Zoyi Capital, and Millennium Technology Value Partners. The company’s existing investors including Sequoia Capital China, SAIC Capital, and Full Truck Alliance (FTA) also participated. This investment is an extension of the $200 million round announced last month, which was led by CPE and Guotai Junan International.

The additional funds will enable Plus to further expand its global operations and commercial deployment plans across the U.S., China, Europe and other parts of Asia for its driver-in autonomous driving solution, PlusDrive. The company is in the final stages of certifying PlusDrive for commercial operation in China.

Mass production for the PlusDrive-powered automated truck jointly developed with FAW, the world’s largest heavy truck maker, is set to start this summer. Plus is working with some of the largest fleets in the U.S. and China, such as SF Express, China’s largest logistics company, to pilot commercial freight operations. Truck makers and fleet partners recognize the multitude of benefits delivered by PlusDrive in terms of improved safety, efficiency, comfort, and sustainability.
