This was the first C11 built for the 1990 World Endurance Championship, for which it was used throughout the season. Although it debuted as the #1 car at Suzuka, it was raced as the #2 for the remainder of the season. It was raced to second at Monza by Karl Wendlinger and Jochen Mass and the Austrian/German pairing later in the year won the Spa round after starting second. Retired from active duty at the end of the year, chassis 90.C11.01 was later acquired by the ROFGO Collection.
