ENASA (Empresa Nacional de Autocamiones S.A.) was a Spanish vehicle manufacturing company, incorporated in 1946 having bought the automotive assets of the Spanish arm of Hispano-Suiza. It produced trucks, buses and military armored vehicles under the Pegaso and, for a short while, Sava brands. Enasa belonged to the state-owned INI industrial holding. From 1983 Enasa also owned Seddon Atkinson, which it received from International Harvester as compensation for a planned engine plant which had failed to materialize. International Harvester pulled out as the market for truck engines was contracting at the time, while there were also problems with Spain's admittance to the European Economic Community (EEC). In 1990 Enasa was sold to Iveco.
