Audi Tradition
Audi V8 Avant 3.6 prototype (1989)
Built at the insistence of Ferdinand Piëch as a fully functional, road-approved family car for his wife Ursula Piëch, it remains one of the most unusual and storied vehicles ever produced by the brand.
Auto Union Type A (1934)
In 1933, Auto Union commissioned Ferdinand Porsche to design a racing car capable of competing under the newly introduced 750 kg Grand Prix formula, which limited vehicle weight but placed no restriction on engine displacement.
