The Soriano-Pedroso was a French automobile manufactured in Biarritz from 1919 until 1924. Built by two Spaniards the Marques de San Carlos de Pedroso and the Marques de Ivanrey Ricardo Soriano Sholtz von Hermensdorff, the original models were Ballot (automobile)-engined 1131cc and cars. The men next built a Ruby-engined cyclecar, and designed the prototype for a straight-eight; their main product, however, was marine engines.
