what was the relationship between auto union and nsu
Auto Union As well as acting as an umbrella firm for its four constituent brands (Audi, Horch, DKW, Wanderer), Auto Union is widely known for its racing team (Auto Union Rennabteilung, based at Horch works in Zwickau/Saxony). The Silver Arrows of these two German teams (Mercedes-Benz and Auto Union) dominated not only GP car racing from 1934 onwards but set records that would take decades to beat, such as the fastest speed ever attained on a public road (at 432.7 km/h (268.9 mph), unbroken as of 2013).[3] After being reduced to near ruin in the aftermath of World War II, Auto Union was re-founded in Ingolstadt, Bavaria in 1949, ultimately evolving into the modern day Audi company following its takeover by Volkswagen in 1964 and later merger with NSU Motorenwerke in 1969.
