Peugeot 8Aa
The Peugeot 8Aa, or L112, is a water-cooled V8 aircraft engine that equipped the Voisin VIII bombers and escort fighters built during World War I. The engine was designed to meet a 1915 request from the French armament ministry for aero engines capable of long endurance at high altitudes. Peugeot responded to the ministry’s request with a design based on their successful racing car engines.
