Reliability though was poor and by the end of the season, he had only been classified in five races and even in two of these, he was not running at the finish due to running out of fuel (the ARC1 was known to have the smallest fuel tank of the atmospheric cars in 1988). However, one finish was fourth on the streets of Detroit where de Cesaris managed to stay out of trouble and quietly moved into the points as the crumbling track surface and the heat took its toll on the field. Finishing fourth in the last ever F1 race in Detroit earned the team three points.
