The M113 E50 engine is an unusually lightweight, compact engine (unlike its predecessor M119) was a continuation of the line of three-valve M112 engines. The engineers added two more to the six cylinders and got the M113. Due to its compactness, it was installed on all rear- and all-wheel drive Mercedes models. Each cylinder has three valves (two intake and one exhaust), and in the M113 engine, the area of the exhaust valve is 30% less than the total area of the two exhaust valves in its predecessor, in addition, it has less weight (the rod is filled with sodium).

Disadvantages of the M113 E50 engine
- The main problem of the power units of this family is the huge oil consumption.
- The main cause of the oil burner is usually hardened valve stem seals.
- Due to contamination of the crankcase ventilation, the lubricant presses through gaskets or seals.
- Also, the source of leaks is often the oil filter housing and heat exchanger.
- Another branded engine failure is the destruction of the crankshaft pulley.
