Audi traces back to 1899 when August Horch made a brand of cars called Horch to compete with mercedes.  But August Horch had a dispute with his business partners losing the rights to the Horch business. So he started a company and called it Audi which is latin for horch or hark. In 1932, Audi joined with 3 other companies creating the first 4 companies of the Auto Union which is repreasented by the overlapping rings in their logo.
