The Hispano-Suiza 12-15 made its debut in 1907. The car featured a small four-cylinder engine with an output of around 15hp. Like many cars of the day, it found itself in various body configurations. Other models quickly surpassed the car's power within even a year, and by 1912 the car seemed out of date compared to the Hispano-Suiza Alfonso XIII model, which produced 64hp.
