M-Hero Automotive Technology Co., Ltd. (Chinese: 东风汽车集团股份有限公司猛士汽车科技公司), commonly known as Mengshi Automotive Technology Co., Ltd. or M-Hero, is a Chinese state-owned subsidiary of Dongfeng Motor Corporation specializing in high-performance luxury off-road electric vehicles. The brand name "Mengshi" (猛士, literally: Fierce warrior) is inherited from Dongfeng's military vehicle line. M-Hero focuses on producing advanced electric vehicles (EVs) and extended-range electric vehicles (EREVs) for the civilian market.

M-Hero was established in 2022 as a subsidiary of Dongfeng Motor Group (DFG), a listed company under the larger Dongfeng Motor Corporation (DFM). While M-Hero operates in the consumer automotive sector, Dongfeng Mengshi (东风猛士), a separate entity under DFM, focuses on military vehicle production. The distinction between the two brands lies in their parent companies and market focus, with DFM's military operations being largely classified.

In 2023, M-Hero unveiled its first production model, the M-Hero 917, a full-size luxury off-road SUV available in both EV and EREV configurations. The vehicle boasts over 1,000 horsepower and a range of 505 kilometers (314 miles), positioning it as a high-performance competitor in the luxury EV market.

In September 2025, Dongfeng Motor Group announced that it, along with Xiangyang Holdings, Xianggao Investment, and Dongfeng Motor Limited (DFL), a joint venture with Nissan, signed an investment agreement to establish a joint venture. DFM, DFL, and the local state-owned enterprises of Xiangyang city formed this partnership. The company will collaborate with Huawei, sharing the M-Hero brand with M-Hero Technology, to develop lightweight off-road SUVs led by Yinwang under the new HI Plus Mode.

M-Hero's product lineup focuses on high-performance luxury off-road vehicles. Key models include:
