Audi was founded in 1909 by engineer August Horch in Zwickau, Germany, as a successor to his earlier Horch company. Notable models include the prewar Type 35 racing car, the postwar 1965 F103 series that relaunched the brand, the enduring 1969-introduced 100/G series (later A6), and the modern A4 and Q5 lines that define Audi’s core in luxury sedans and SUVs. Today, Audi is a pillar of the Volkswagen Group, selling across Europe, North America and Asia with a growing electric portfolio led by the e-tron crossover. The four-ring logo symbolizes Audi’s Auto Union heritage, and its slogan “Vorsprung durch Technik” underlines a long commitment to tech-driven refinement.
