Under patronage of state-owned automobile company

Following February 1948, a period of insensitive interventions in the soccer movement started, the contests were reorganised several times and new physical training unions and clubs came into being within the framework of the unification of Czechoslovak physical training. Moreover, an amalgamation of the biggest local clubs started in Ml. Boleslav too. A gradual and often painful process was accomplished with the establishing of one main physical training union, in which soccer players of SOKOL AZNP Mladá Boleslav and from 1950 SPARTAK Mladá Boleslav, with another two reserve teams, were also concentrated. In 1952, Spartak Ml. Boleslav got into the so-called all-state competition, which was basically the second league. With the exception of the year 1959 when it was relegated for one year, the club played continuously, even if called by different names.

In 1964, the soccer players enjoyed the new Central Stadium (municipal today) for the first time, which was officially opened for the Spartakiáda one year later in 1965. It was designed to serve not only the Spartakiáda but also as the finish of the then very popular "Freedom Race" cycling race, and the main sports ground had a clinker concrete athletics track. In 1966, TJ Spartak was renamed as TJ AUTO ŠKODA, which had 23 sports branches, including soccer. It was especially successful in soccer in the eighties when literally sponsored by the motor works (AZNP), which even took over the stadium and engaged the players chiefly as fire fighters.

In the years 1983, 1984 (trainer Petr Polák) and 1986 (trainer Jaroslav Dočklal) the Auto Škoda team finished in 3rd place and it was disseminated that at that time there was no official interest in backing up its first league admission. One success was its participation in the final of the Czech cup in the 1977-78 season when Baník Ostrava beat Auto Škoda 1:0 at home before 5,500 spectators and in the return match the rival won 2:0 on its playing field.
