'Vorsprung durch Technik' is one of the most enduring marketing slogans in the automotive industry – and one that has truly given expression to Audi’s focus.

It was first used in 1971 to showcase the technical diversity of the NSU range, then encompassing water-cooled front-drive, air-cooled rear-drive and rotary-engined models. But it really came into vogue in the 1980s with the radical Audi Quattro. At one point, the slogan was featured on the largest illuminated advert in Europe.
