Reminds me of the records Mercedes diesels broke in 1976 in the 617 powered C-111.
Wondering where to go next with the project, Mercedes struck upon idea of using diesel engines to set speed records and the engineers were sent back to their labs to sort it out. The engine suggested was the five-cylinder three-litre naturally aspirated diesel from the 240 D 3.0 and 300 D, an engine with plenty of potential for raising performance.
With a Garret turbocharger and an intercooler, the production engine’s output of 80 hp was boosted to a proud 190 hp to power the C 111-II. It was rolled out for a record attempt at the brand-new test track in Nardo on June 12, 1976. Four drivers, who took turns at two-and-a-half hour intervals, drove this car from one diesel record to the next over a time-span of 60 hours. 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. The diesel had proved its ability to race.
