UMW Toyota Motor (UMWT). The UMW group has held the Toyota franchise ever since. The Assembly Services plant is further supplemented by sister companies of UMW Toyota, most notably Automotive Industries (AISB) and Toyota Boshoku UMW (TBU) which manufacture exhaust systems and interior components respectively. UMW Toyota subsidiaries also supply components to non-Toyota plants in Malaysia and abroad. Additionally, Toyota is the sole foreign car company to carry out body panel stamping operations for select Malaysian-built models through its subsidiary, Toyota Auto Body Malaysia (TABM). In 2016, UMW and Toyota announced plans for a second Toyota assembly plant in Bukit Raja, with a capital investment of RM2 billion. Construction of the second plant was completed in late 2018, and operations commenced in January 2019 with the debut of the revised third generation Vios. Go Automobile Manufacturing Go Automobile Manufacturing Sdn. Bhd. (GAM) currently operates an assembly plant in Gurun with an annual capacity of 25,000 units. GAM assembles Haval and Great Wall Motors (GWM) vehicles for both domestic and export markets. Go Automobile Manufacturing is a subsidiary of Malaysia-based Go Auto Group of Companies. Go Auto is the appointed distributor, assembler and exporter of Haval and Great Wall Motors vehicles for the ASEAN region. The Go Auto plant was established in the late 2000s by MAZS Sdn. Bhd., a subsidiary of Green Oranges Sdn. Bhd. (GOSB). In mid 2011, Green Oranges imported the first Great Wall vehicles into Malaysia, and local assembly operations commenced later that year. In April 2014, Go Auto became the first company to be awarded with an Energy Efficient Vehicle (EEV) manufacturing license from MITI. The Green Oranges plant was subsequently developed into Go Automobile Manufacturing, and further investments into a second, adjacent facility increased production capacity from 10,000 units annually to 25,000 units by 2015. The Go Auto plant is located across the street from the Naza Automotive Manufacturing plant. The Go Auto plant employs a unique 'factory-in-factory' or 'Tier 0' approach, in which component suppliers or vendors are invited to directly participate in automobile assembly by setting up smaller factories within the larger plant itself. Each vendor concentrates and specialises on a specific section of the assembly line, while Go Auto supervises the overall assembly process. All vendors co-ordinate and co-operate with each other to solve problems and achieve high quality control standards. The 'Tier 0' system aims to develop and enhance local vendor
