The Zavolzhye Engine Factory (Russian: Заволжский моторный завод, romanized: Zavolzhskiy Motorniy Zavod, 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 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 (51 kW) at 4,000 rpm and 167 N⋅m (123 lb⋅ft) at 2,200 rpm. The first engine was assembled 4 November 1959; by December 1968, ZMZ had produced one million units. More information...
