1912 - 1936
In 1911, production of the Hispano cars first began in Spain, but later were manufactured in France.
After World War I, Hispano-Suiza returned to automobile manufacturing and, in 1919, introduced the H6. The H6 featured an inline 6-cylinder overhead camshaft engine based on the features of its V8 aluminum World War I aircraft engines and a body design by the American coach designers Hibbard & Darrin.
Through the 1920s and into the 1930s, Hispano-Suiza built a series of luxury cars with overhead camshaft engines of increasing performance. On the other hand, in the 1930s, Hispano-Suiza's V-12 car engines reverted to pushrod valve actuation to reduce engine noise.
