If such an article had been written twenty or thirty years ago, its message would have been unequivocal - Mercedes power units may not be the most innovative, but among competitors’ engines there are unlikely to be more durable ones.

Today, Mercedes engines use a large number of technical innovations designed to reduce harmful emissions and improve performance while reducing fuel consumption. Unfortunately, this negatively impacted the legendary durability. And if nothing terrible still happens to the engine block and head, then malfunctions of the injection system or supercharger have become something common. Elimination of defects, as a rule, requires large expenses. It is gratifying that the company quickly learns from its mistakes and overcomes them quite quickly.
