The late 1980s marked the successful return of Mercedes-Benz to the international racing circuits following the automobile manufacturer’s departure from circuit racing in the year 1955. In 1984, Mercedes-Benz agreed to supply engines for the prototype sports cars of the Swiss racing team of Peter Sauber used in the Group C motor racing series. Four years later, Mercedes-Benz officially returned to the starting line with the Sauber-Mercedes C 9. In addition to their unique technical features, the sports cars were also given a new look with the striking silver paint, which clearly signalled that Mercedes-Benz had again entered into the competition. In the years from 1989 to 1990, the new silver arrows took home a total of 16 victories from 18 races. One highlight was the double victory at the legendary 24-hour race in Le Mans in 1989.
