Why is it called Audi?

The name "Audi" derives from the Latin translation of the surname of the company's founder, August Horch. In German, "horch" means "listen," and the Latin equivalent is "audi." Thus, when Horch founded his new car company in 1909 after leaving his first company, he chose the name Audi as a nod to his legacy and the meaning of his last name.
