The factory was built in Barcelona and soon started producing electric cars and airplane engines. In fact, Hispano-Suiza first became known as an airplane manufacturer and moved to full-time luxury car production after the First World War. The aircraft production standards, perfect engines, and dedication to details separated Hispano-Suiza from the rest of the premium car companies from the era. During the ’20s and the ’30s, beautiful bodies and powerful engines made Hispano-Suiza popular with the wealthy European customers.
