[PAR] [TLE] Hispano-Suiza 12Z [SEP] The 12Z, designated Type 89 by the company, was the final evolution of the series of Hispano-Suiza V-12 aircraft engines.  The Z model had just entered production when France fell to the Germans during World War II.  A small number were produced during the war but the German occupation government would not allow full-scale production to start.  After the war small numbers were built to equip new designs, but the rapid introduction of the jet engine ended further development. [PAR] [TLE] Hispano-Suiza 12Y [SEP] The Hispano-Suiza 12Y was an aircraft engine produced by Hispano-Suiza for the French Air Force in the pre-WWII period.  The 12Y became the primary French 1,000 hp (750 kW) class engine and was used in a number of famous aircraft, including the Morane-Saulnier M.S.406 and Dewoitine D.520.  Its design was based on the earlier and somewhat smaller, 12X.  A further development was under way, the 12Z, but ended due to the German occupation of France.
