Audi history: from August Horch to quattro, the A8 and e-tron

By CarWhere Research · Updated

Audi began in 1909, when August Horch founded a new carmaker and named it with the Latin translation of his surname. In 1932 Audi, DKW, Horch and Wanderer merged as Auto Union, the origin of the four rings. Volkswagen revived the Audi name in 1965, and quattro all-wheel drive followed in 1980.

  1. 1899

    August Horch founds his first company

    August Horch, who had managed motor-vehicle production at Carl Benz in Mannheim, founded A. Horch & Cie. in Cologne on November 14, 1899. He moved the business to Zwickau in 1904 and turned it into a corporation.[1],[2]

  2. 1909–1910

    Horch becomes Audi

    After leaving his first company in 1909, Horch founded a new carmaker in Zwickau. Barred from using his own name, he used its Latin translation: "horch" ("listen!") became "audi." He delivered the first Audi-badged car in May 1910, and Audi won the Austrian Alpine Rally three years running from 1912 to 1914.[2],[3]

  3. 1932

    Auto Union and the four rings

    On June 29, 1932, Audi, DKW and Horch merged, and Wanderer's car division joined them, to form Auto Union AG, Germany's second-largest carmaker. The four interlocking rings stood for the four founding companies.[1],[2]

  4. 1934–1939

    Silver Arrow racing

    Auto Union's mid-engined Grand Prix cars, designed under an agreement with Ferdinand Porsche, debuted at the Avus in May 1934. In October 1937 Bernd Rosemeyer became the first driver to exceed 400 km/h on a public motorway.[1]

  6. 1958–1965

    Daimler-Benz, then Volkswagen

    Daimler-Benz took over about 88 percent of Auto Union in April 1958 and the rest in 1959. Volkswagen bought the company in 1965, the same year the first post-war Audi, with a four-stroke engine, revived the Audi name.[1],[3],[4]

How to check a Audi's factory build

Standardized 17-character VINs began with model year 1981[42]. For a 1981-or-later Audi, CarWhere can check a VIN for licensed factory build data and, when it exists, list the equipment the vehicle was built with in plain English: see the Audi build sheet by VIN. Coverage varies by VIN and model year. Earlier vehicles are identified by their original serial number, vehicle data plate and engine stampings instead.
