Kompressor (stylized as KOMPRESSOR) is a marketing name for forced induction (supercharged) Mercedes-Benz engines. The term is not widely used by other motor manufacturers. The first Mercedes supercharger was developed in 1921 by a Daimler-Benz team with assistance from Ferdinand Porsche. Mercedes became the first manufacturer to install superchargers on some production models. The designation "K" on Mercedes usually means "Kurz", or short, but can mean "Kompressor".
