Zavolzhye Engine Factory

The Zavolzhye Engine Factory (, ZMZ) is a Russian automotive engine producer.
The plant was founded in April 1958 to provide GAZ with engines, in particular for its new GAZ-21 Volga.
The factory's first product was a brand-new OHV engine. Unusual for the era, it had aluminum block and head, with chain-driven camshaft and compression ratio of 6.6:1; it produced at 4,000 rpm and at 2,200 rpm. The first engine was assembled 4 November 1959; by December 1968, ZMZ had produced one million units.
ZMZ became independent in 1961, and was bought by UAZ in 2001. It produces spare parts for many vehicles of Soviet origin, as well as for some Ford models.
