The Andrea Moda fashion company, owned by Andrea Sassetti, had bought the Coloni team, which had failed to pre-qualify at every race of the 1991 season. They had signed ex-Footwork driver Alex Caffi, and Enrico Bertaggia, who had driven for Coloni during the 1989 season, and had brought the Judd-engined Andrea Moda C4B to South Africa. This car was an adaptation of last season's Cosworth-powered Coloni C4. Caffi drove in the second of Thursday's acclimatisation sessions, although the car's battery failed on the first lap. Bertaggia did not run, and it was unclear if a second C4B had been built, or brought to Kyalami. However, a Stewards' Meeting on Thursday afternoon ruled that Andrea Moda was a new team, not a continuation of Coloni, and were therefore liable to pay a $100,000 guarantee according to Article 41 of the Formula One Sporting Regulations. The stewards also noted that the C4 cars were originally built, and had been raced, by another constructor, i.e. Coloni, not Andrea Moda, thus the cars were likely to be ineligible, as a new team must use an original chassis. In any case, failure to pay the guarantee meant exclusion from the event.
