Mercedes got a lot of mileage out of their OM617 diesel engine. It was a straight 5-cylinder block, and could have been built with or without a turbocharger. Popular for its reliability, the engine was put into many different vehicles. One of which was the 300TD; a 5-door wagon offered by Mercedes between 1979 and 1987. Early models were naturally aspirated, only putting out 77hp. After the addition of the turbo, power output nearly doubled to 125hp. This was a much needed improvement, since the wagon weighed almost 4,000-lbs. Most of the Mercedes-Benz 300TD parts were the same as other 123 vehicles, since they shared a lot of the same underpinnings and were built from the same platform.
