The OM617 engine family was a straight-5 Diesel automobile engine from Mercedes-Benz used in the 1970s and 1980s. With some Mercedes-Benz 300D/300SD diesel engines already exceeding 500,000 miles, it’s considered to be one of the most reliable engines ever produced. The OM617.912 was a 3.0 L (3005 cc) engine.
The engines came in The W114 chassis which used the straight-6 engines and were sold under the more common “230”, “250”, and “280” model names.
Although it only produced a puny 65 horsepower with top speeds hardly exceeding 85 miles per hour, it was enough to be touted as the fastest diesel car at that time with a 4-cylinder, 2.4 liter engine. By 1976, it featured the demise of production of the W115 chassis with the migration to the W123 chassis. This also highlighted the release of the more powerful version that is the 88-hp Mercedes Benz 300D.
Some diehard owners still drive their diesel Mercedes, partly because when taken care of, the car lasts far longer than most, and the 5 cylinder diesel gets about 32 to 35 miles per gallon of diesel fuel. Diehard owners tend to fix their mighty cars. That is part of the philosophy of owning a diesel car like this. Many people purchased these cars knowing they would make repairs as needs and drive the car far longer than most.
When I was kid my cheapskate cousin had a 1959 Mercedes, a 1.9L 190D 50hp version of the diesel with the new unibody W 121 chassis. It was hard pressed to go 70 MPH, yet it got almost 50 miles per gallon of diesel. Of course, at that point in my life, a big block Chevy was more interesting.
Diesel engines are not new, we are employing them more and more in our modern vehicles. Mercedes had a good head start on everyone else. That being the case, plenty of modern vehicles are using diesel power now, partly because they get better fuel mileage than the comparable gasoline engine and partly because diesel engines are more environmentally friendly.
