Audi scale model cars document one of motorsport's most dominant chapters — five consecutive Le Mans wins from 2000 to 2004, Quattro-powered WRC glory in the 1980s, and DTM championships that defined German touring car racing across three decades. The Vroomi catalogue covers Audi R8 and R10 TDI Le Mans prototypes, the quattro S1 Group B rally car, DTM grid cars from the V8 quattro era to the RS 5, and selected road car icons — reproduced by Spark, Minichamps, and IXO at 1/18 and 1/43 in resin and die-cast formats. The depth of subject matter across different disciplines makes Audi one of the strongest single-marque collecting areas for the enthusiast with a motorsport focus. A grid that spans eras and categories with real purpose.
