The story
The division has its origins in a reorganization of the automotive companies owned by the Siberian Aluminum holding (later Basic Element), which were consolidated under the RusPromAvto consortium. RusPromAvto (Russian: РусПромАвто) was created on 7 August 2000 and combined several Russian bus manufacturers. LiAZ was added to the group in 2001.
It became known as Russian Buses (Russian: Компания Русские Автобусы, romanized: Kompaniya Russkiye Avtobusy) in May 2004, and was based in the village of Maliye Vyazemy in Moscow Oblast. In 2005, during the restructuring of the production assets of RusPromAvto, the company was incorporated into the GAZ Group.
