Mercedes 300CD

The Mercedes 300 CD was part of a series of executive sedans built by the German automaker between 1976 and 1985, based on the W123 platform. The W123 series was the most successful Mercedes-Benz ever produced, with nearly 2.7 million cars sold during the production run. Mercedes W123 have been featured in film, a Warner Brothers cartoon (driven by Porky Pig) and a number of editions of the video game Grand Theft Auto.

The 300CD itself was powered by a diesel engine, as signified by the "D". The first generation first rolled off the assembly line in 1978 and was powered by a 77 horsepower inline five cylinder engine, known as the OM617. In 1981, that engine was upgraded to 83 horsepower. The second generation appeared later that year; a turbocharger was added, raising the horsepower rating to 125. Production of the Mercedes 300CD came to an end in 1985. Mercedes 300CD MPG was over 30, on the average.

More than thirty years later after the last model rolled off the assembly line, many Mercedes 300CD sedans are still running strong; the OM617 is widely considered to be among the most durable and reliable engines ever developed, able to go for well beyond the 600,000 mile mark before requiring an overhaul. Five cylinder engines were not new: the Ford Motor company attempted to develop one in the 1930s for use in a proposed economy model. It was also common in early aircraft rotary engines. However, the Mercedes OM617 was the first inline five cylinder engine to be mass produced and installed in a production vehicle.

A five cylinder engine offered distinct advantages over an inline six, at least at lower to mid-range engine speeds; there is a power stroke with every 144 degree turn of the crankshaft, and since every power stroke lasts 180 degrees, with five cylinders, there is always a power stroke. Such an engine loses less power due to friction than an inline six. However, because there is less overlap of power strokes, it runs less smoothly at higher RPMs than a six-cylinder motor.

In addition to the sedan configuration, the Mercedes W123 was also available as a coupe, a limousine and as an ambulance or hearse. Base models were equipped with a three speed automatic or a four or five speed standard transmission. A Mercedes Benze 4G-Tronic four speed automatic was available as an option during the last three years of production. Like the OM617, it is extremely reliable, known to operate for more than 300,000 miles.

If you are considering a used Mercedes 300CD for sale, you will want to make certain it has been properly maintained and cared for. As long as its maintained the Mercedes 300CD diesel will go almost indefinitely. Of course, you will need a source for parts in order to keep it in top conditions. As is the case for many German cars, Mercedes parts and components can be expensive. This is why it pays to check out PartsGeek.com, an online discount auto parts retailer that offers a range of automotive parts for as much as 80% off.
