It approved the constitution of the company Diesel Nacional, SA, with a duration of 45 years and a capital stock of 75 million Mexican pesos, which was contributed by the private sector and government, with the latter being the majority shareholder.

In 1962, the Mexican government imposed limitations on the automotive industry, which included tariff barriers on the importation of vehicles entering Mexico, for both freight and passenger transportation, as well as obtaining their components from abroad.

Other policies served as important factors for the export of freight trucks to several Latin American countries starting in the 1970s.

In 1974, the Maquiladora Automotriz Nacional Company (MAN) was formed to assemble pickup trucks with the DINA brand.

Due to the growing demand and diversified in its line of products, from 1976 different commercial divisions were created within Diesel National SA, remaining as the main controller and forming a decentralized parastatal corporate group.

Reasons for this were unfair competition practices by other companies, with prices below actual cost, and the consolidation of previously imposed tariff restrictions.

During that decade DINA Autobuses reached their sales peak, led by CEO Miguel Ángel Anguiano Rodríguez.

Thus, from 1988 to 1989, the corporate liquidation process of DINA was carried out, which ended with the sale of the existing companies in the group (trucks, engines, plastics and buses) in a stock package.

In 1989 the parastatal Diesel Nacional, S.A. (trucks, engines, plastics and buses) was acquired by Consorcio Grupo G S.A. de C.V., owned by the Rafael (†), Armando, Guillermo, Alfonso and Raymundo Gómez Flores brothers, from Jalisco.

The Gómez Flores family was a shareholder in Mexicana de Autobuses S.A. (MASA), through Motor Coach Industries (MCI).

During the first years of privatization, it maintained commercial relations with partners who had obtained agreements during its stage as a parastatal company.

That same year, Grupo G acquired the assembly plants of Motor Coach Industries to facilitate exports to the North American market.

In April 1999, the production, assembly and sales of its own range of HTQ (High Technology and Quality) of chassis and trucks in Argentina began: D1416, D1721 and D1725.

At the end of the 1990s the company had several subsidiaries and operating groups: In 1997 new models of buses and trucks were built in the Sahagún plant, based on their own designs and entirely Mexican.

On October 28, DINA filed a claim for breach of contract with Western Star Trucks with the International Chamber of Commerce for US$110 million.

In February 2001, the resizing of the company DINA Trucks for the resumption of regular operations without the Western Star contract was evident.

On September 11, 2001, the DINA Trucks plant in Ciudad Sahagún, Hidalgo, was shuttered due to the termination of a 52-year union with the Federal Government.

The government of the state of Hidalgo led by Manuel Ángel Núñez Soto, took charge of the assets of the company, only of DINA Camiones, liquidating its 559 workers in the year 2002.

In 2001, to avoid bankruptcy, a group of administrative staff of Grupo Empresarial G, owners of the company remnants, carried out the financial restructuring of DINA Camiones.

Subsequently, problems arising due to the cancellation of the contract with Western Star Trucks, was settled by legal means.

By increasing their participation in the Mexican market once again, DINA resumed exporting units to some countries in Central America, where certain models of the company currently circulate.
