Founded in 1909 by August Horch in Zwickau, Germany—he named it “Audi,” the Latin for “listen,” after legal issues prevented him using his surname . In 1932, Audi joined with Horch, DKW, and Wanderer to form Auto Union, adopting the four interlinked rings logo to symbolize the four brands . Now part of Volkswagen, Audi is known for luxury vehicles, the slogan “Vorsprung durch Technik,” and innovations like quattro AWD .
