The Auto Union Grand Prix racecar turns 90 – a chapter in the “Anniversary Dates 2024” booklet from Audi Tradition tells the story. The new Auto Union racecar officially appeared at the AVUS in Berlin on March 6, 1934, with Hans Stuck at the wheel. On May 27, 1934, the Auto Union Type A, as it was named internally, debuted on the international racing scene, ushering in the thriving era of the Auto Union Silver Arrows.
