Saturday 12th June 1976
Four drivers, who took turns at two-and-a-half hour intervals, drove Mercedes C 111-IID from one diesel record to the next over a time-span of 60 hours at the brand-new test track in Nardo. In the end, a total of 16 new records had been established – those over 5,000 miles, 10,000 kilometers and 10,000 miles even were absolute world records, i.e. independent of the type of engine. Speed averaged around 150mph.
