Apparently it used the 617 NA engine that they must have just developed. With a turbocharger and intercooler they were able to get 190HP. Just an interesting fact as Im sure you all know this existed and they had a diesel but I for one never knew it used a 617. Maybe someone should call up an old team member and ask how they did it?

Also anyone got pics of the engine bay of this oil burner?

The C111-III made about 230hp.

Cool... It would be nice if they came out with a modern version...

I want to know how they got that 617 to pump 170kw out for 12 hours non stop (and managed 14.7mpg)

More fuel, more boost and the usual oil cooled pistons and oil coolers.

I imagine they did all the things they did on the production turbo motor and then some, but I imagine it was simply the same stuff taken to a higher level.

And then it took them 10 years to give us the turbo diesel car. Amazing. Know wonder these engines are so great

The 300SD with a turbo 617 came out 2 yrs later (1978)

I thought the 617 powered C111 was made in 69

In 1976, Mercedes-Benz decided to disprove the old prejudice - and what could have been better suited to providing counter-evidence than a C 111 with diesel engine? The engineers installed a three-liter naturally-aspirated compression-ignition engine with five cylinders in the C 111-II for the first tests. In the car, now called C 111-IID, the OM 617 LA engine developed as much as 190 hp, thanks to turbocharging and intercooling, as opposed to the 80 hp output of the production engine which powered the Mercedes-Benz 240 D 3.0 (W 115, Stroke Eight) and, at a later stage, other models. In June 1976, the C 111-IID reached spectacular speeds on the test track at Nardo near Lecce in Italy. In the course of 60 hours, four drivers established a total of 16 world records - thirteen of these applying to diesel-engined cars and three to cars in general, irrespective of their type of engine. During the tests, an average speed of 252 km/h was recorded, and Mercedes-Benz proved impressively that diesels also have sprinter qualities.

Looks nice in person doesn't it. Let me see.....Ah! Here they are.

The orange road car version was in the gift shop. The silver test car was located in the Hall Of Concepts on the wall. Good old fashioned aeromodding for yer.
