OAO "Serpukhov Motor-car Factory" is the biggest engineering plant in Moscow region. The factory is specialized in "Oka" cars production and sale, as well as their spare parts.

Nowadays OAO "SeAZ" countinues the glorious working traditions of many generations, being supported by its long-term experience, and starts realizing new projects with confidence.

The "Serpukhov motor-car factory" was founded July 7th, 1939. 

That day two orders were signed: by the People's Commissar of General Engineering Industry and by the head of "Glavmotoveloprom", concerning production of small capacity motorcycles.

From 1939 to 1995 the factory produced motorcycle-cars of different modifications.

From the beginning of 1980th the factory enters the period of its development: new car prototype was designed and produced, and it got "Oka" name and anticipated the car produced nowadays.

In 1985 the USSR Council of Ministers issued a decree "About creation of new capacities for production of a new model of extra-small car at "AvtoVAZ" and "KamAZ" corporations and at Serpukhov Motor-car Factory, all belonging to the USSR Automotive Industry Ministry".

The Serpukhov factory was significantly rebuilt for the new tasks. The leading enterprises as well as foreign companies were entrusted with the equipment for production and assembling: Durr, Bollhoff and PPG. In 1989 in the context of this program realization, the factory started assembly of the first cars of the extra-small class. At the time the factory entered to "AvtoVAZ" corporation.

In the middle of 1995 "AvtoVAZ" corporation fully transferred the "Oka" assembly to "SMZ". The factory’s name was changed to "Serpukhov Motor-car Factory" ("Serpukhovsky Avtomobilny Zavod" – SeAZ).

In 2005 OAO "SeAZ" became a member of  the "Avtokom" industrial group.
