Overview
Shinjin Motors, also spelled Sinjin Motors, was a South Korean automobile manufacturer active primarily from the 1960s through the late 1970s. Its origins lay in Shinjin Industrial Company, founded in 1954 as a producer of automotive parts. The business entered vehicle repair and rebuilding in 1958, working on vehicles used by the United States Army, and began actual vehicle assembly in 1962. The company expanded during a period when the South Korean government was attempting to establish a domestic automotive industry through import restrictions, subsidies, tariff exemptions for parts, and selective licensing. In 1964, the government designated Shinjin as an authorized automobile producer, and in 1965 the company took control of the former Saenara Motors plant in Bupyeong, Incheon. Shinjin briefly experimented with Mitsubishi technology before forming a more consequential technical and manufacturing relationship with Toyota in 1966. Toyota-based production transformed the company. The Shinjin Corona, introduced in May 1966, became one of the most successful locally assembled passenger cars of its period, while the Publica, Crown, commercial trucks, and buses broadened the company's range. Shinjin also assembled or licensed-built vehicles based on Toyota, Isuzu, and Hino products. Its success helped increase South Korean automotive output, but its privileged position attracted criticism from competing industrial groups. The government subsequently authorized additional manufacturers, including Hyundai, Asia Motors, and Kia, ending Shinjin's effective passenger-car monopoly. Toyota's relationship with Shinjin was eventually displaced by geopolitical and commercial considerations. In 1972, Toyota transferred its interest to General Motors, which formed a 50-50 joint venture with Shinjin known as General Motors Korea, or GMK. GMK produced vehicles derived from Holden and Opel designs, including the Chevrolet 1700, Record 1900, and Camina, as well as commercial vehicles. Several passenger-car products struggled because of fuel consumption, pricing, or weak performance in the aftermath of the 1973 oil crisis. Shinjin also entered the four-wheel-drive market through a 1974 alliance with American Motors. Shinjin Jeep Motors produced hardtop and soft-top Jeep vehicles under license. American Motors withdrew from the venture in 1979, after which the company became a domestic corporation and continued under the Shinjin Motors name. The Jeep operation was renamed Keohwa in 1981, acquired by Dong-A Motors in 1984, and ultimately became part of the corporate lineage that led to SsangYong Motor Company. The separate GMK business followed another path. Financial difficulties led Shinjin to sell its interest in GMK to the Korea Development Bank in November 1976. GMK was renamed Saehan Motors, and the stake later passed to the Daewoo Group. Thus, although Shinjin Motors no longer survives as an independent manufacturer, its manufacturing operations and vehicle programs contributed to the later histories of Saehan, Daewoo, Keohwa, Dong-A, and SsangYong. The brand is remembered as one of the foundational companies in South Korea's modern automotive industry.
History
Shinjin Industrial Company began in 1954 as an automotive-parts producer. It entered vehicle rebuilding in 1958, primarily handling United States Army vehicles, and moved into actual assembly in 1962. That transition coincided with the South Korean government's Automotive Industry Promotion Law, which restricted imports of assembled automobiles and used subsidies, parts exemptions, and selective licensing to encourage domestic manufacturing. After the collapse of Saenara Motors, Shinjin was designated an authorized automobile producer in 1964 and took over Saenara's plant in Bupyeong, Incheon, in 1965. Its first foreign technical experiment involved Mitsubishi Motors and the assembly of Colt vehicles, but the arrangement ended after about a year amid concerns that it did not support the government's localization goals. Shinjin then established a Toyota partnership in January 1966, approved by the government the following month. Toyota-based production began with the Corona in May 1966. The model became a commercial success and helped increase Shinjin's assets substantially. The company expanded into small cars with the Publica, luxury vehicles with the Crown, and commercial vehicles and buses using Toyota, Isuzu, and Hino technology. Shinjin's success contributed to the rapid growth of South Korea's automotive output, but its favored licensing position was controversial. The government responded by authorizing additional passenger-car producers, including Hyundai in 1967, Asia Motors in 1968, and Kia in 1971. In 1972, Toyota transferred its interest in Shinjin to General Motors. The new 50-50 joint venture, General Motors Korea, assembled vehicles based on Holden and Opel designs. Its range included the Chevrolet 1700, Record 1900, and Camina, along with several trucks. The Chevrolet 1700 suffered from high fuel consumption during the 1973 oil crisis, while the Camina was discontinued after weak sales. Shinjin's financial problems eventually forced the sale of its GMK stake to the Korea Development Bank in November 1976. GMK became Saehan Motors, later entering the Daewoo corporate lineage. Separately, Shinjin created a 50-50 Jeep venture with American Motors in 1974. Production of hardtop and soft-top Jeep vehicles began that year. AMC withdrew in 1979, leaving the operation as a domestic corporation named Shinjin Motors. In 1981 it was renamed Keohwa, acquired by Dong-A Motors in 1984, and absorbed into the lineage that later became SsangYong Motor Company. Shinjin therefore disappeared as an independent brand, but its factories, partnerships, and vehicle programs were important precursors to several later South Korean automotive companies.

Products and positioning
A pioneering domestic South Korean vehicle assembler that combined government-backed industrial development with foreign technical and licensing partnerships.
Passenger car · 1966
Shinjin Corona
Introduced in 1966 through Shinjin's Toyota partnership, the Corona was a mid-size sedan and the company's most commercially important early passenger car. It used a 1.5-liter four-cylinder engine and later received a 1.6-liter option. Production ended in 1972 after total sales of approximately 44,248 units.
Small passenger car · 1967
Shinjin Publica
The Publica was introduced in 1967 as an economical small car intended to serve an anticipated expansion of private motoring in South Korea. It was offered in two-door, wagon, and pickup forms. Despite public recognition as a small or red car, sales reached only about 2,005 units through 1971.
Luxury sedan · 1967
Shinjin Crown
Introduced in 1967, the Crown was Shinjin's first luxury-oriented passenger car. It targeted industrial executives, government organizations, and police users. The line received several updates, including the Crown Deluxe and the New Crown, and used progressively larger engines.
Bus
Shinjin Microbus
The Microbus used a Shinjin-built body mounted on a Dodge M37 powertrain and chassis because Shinjin could not yet manufacture the complete mechanical package. It became one of the earliest successful South Korean-built buses and was purchased by many bus operators.
Transit bus
FB100LK
The FB100LK was a large public-transit bus using Isuzu BR20 technology. It was offered in front-engine and rear-engine configurations and became a strong seller as Shinjin competed in Seoul's expanding urban bus market.
Four-wheel-drive vehicle · 1974
Shinjin Jeep
Produced through the Shinjin Jeep Motors venture with American Motors, the hardtop and soft-top Jeep vehicles marked Shinjin's entry into licensed four-wheel-drive production. The operation later became Keohwa and formed part of the lineage leading to SsangYong.
Passenger car · 1972
Chevrolet 1700
Introduced by GMK in 1972, the Chevrolet 1700 was based on the Holden Torana and used a 1.7-liter engine. Although it offered strong performance and reliability, its low ride height and fuel consumption hurt demand during the 1973 oil crisis. Production ended in 1975.
Luxury sedan · 1973
Record 1900
The Record 1900 was GMK's flagship sedan, based on the Opel Rekord D. It entered production in 1973 and was later updated and renamed Record Royal. The program continued after GMK became Saehan Motors.
Passenger car · 1976
GMK Camina
The Camina was launched in 1976 as a successor to the Chevrolet 1700. It retained the earlier car's chassis but adopted a smaller 1.5-liter engine and added interior equipment. The reduced output was poorly matched to the vehicle's weight, and only about 922 were sold before its 1978 discontinuation.
