Al Holbert, who had won Le Mans three times in a Porsche 956 sports car and was fourth in the Indianapolis 500 in 1984, was a test driver but died in a plane crash in September 1988.

One of the three vehicles built is on loan to the Cité de l'Automobile - Musée National - Collection Schlumpf in Mühlhausen, but belongs to the Porsche Museum in Zuffenhausen.

One is now part of the permanent exhibition "Success story: Porsche Motorsport" in the EFA Museum for German automobile history in Amerang / Chiemgau.

Most of the CART teams, apart from Penske Racing or AAR Eagle, did not build their own car, but bought a chassis, e.g., B. from Lola, and equipped it with engines from Chevrolet, Ford-Cosworth, Judd, or Buick.

Similar to the Formula 1 World Championship at the beginning of the 1960s, it was possible to point to a victory - that of Teo Fabi on September 3, 1989, at the Mid-Ohio Sports Car Course.
