Zavolzhye Engine Factory

The Zavolzhye Engine Factory (in Russian, Zavolzhye Motorni Zavod, ZMZ) was a Soviet automotive engine producer.

The plant was begun 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 2,445 cc (149.2 cu in) 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 70 hp (52 kW; 71 PS) at 4,000 rpm and 123 lb·ft (167 N·m) at 2,200 rpm. The first engine was assembled 4 November 1959; by December 1968, ZMZ had produced one million examples.

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.
