From 1983 to 1985, Borgudd raced only on occasion, including his taking part in the 1984 and 1985 Macau Grand Prix. In 1985 he returned to race a Formula 1 car, an Arrows A6, in the new Formula 3000/F1 combined championship finishing 10th in the Vallelunga race. He entered 5 races that season, but the rebuilt F1 cars were not competitive compared to the specified F3000 cars. Although he took part in the 1987 24 Hours of Le Mans, and in 1989 had an outright win in the Willhire 24 Hour, a minor touring car race where he drove a Ford Sierra, the Swede made his mark in truck racing the following years. In 1986 and 1987, Borgudd was champion in Divisions 2 and 3 of the European Truck Racing Championship, respectively. The following years, success was more fleeting, although the Scandinavian driver managed to finish the 1992 Class B championship in third place.
