CS stands for Competition Sport. An abbreviation that only select BMW M automobiles are allowed to bear. First introduced into today's nomenclature with the BMW M4 CS F82, this abbreviation identifies special models that feature technically innovative components. The CS special models carry the tradition of iconic M special models that began in 1988 with the BMW M3 Evolution in the E30 series. Increased engine power, lightweight construction, optimized aerodynamics, sportier suspension and innovative drive components make these models special for M GmbH. In short, the CS models combine sporty dynamics of the highest standard and outstanding performance all while offering the everyday practicality that is typical of all M cars.
