On June 30, 2008, BMW announced plans to revive the Procar series in an exhibition event at the 2008 German Grand Prix at the Hockenheimring. The races involved ten original M1 Procars driven by several drivers who had participated in the original series as well as modern drivers. Each car included a passenger seat for a guest. The line-up included former competitors Christian Danner, Harald Grohs, Niki Lauda, Dieter Quester, and Marc Surer. Former BMW driver Prince Leopold of Bavaria, BMW Sauber test driver Christian Klien, and a current M1 Procar owner, Marco Wagner, also competed. The BMW M1 Art Car designed by Andy Warhol was involved, driven by series founder Jochen Neerpasch and with fellow Art Car artist Frank Stella as his passenger.
