Since its debut in 2016, this little BMW M has undergone several evolutions. From 2017 it benefits from the facelift of the 2 series. The following year it transformed into Competition, changing its tone: the 370hp three-liter N55 turbo gave way to the S55 six-cylinder biturbo of the M3 / M4, increased to 410hp. The CS (Competition Sport) version gains additional power, reaching 450hp at 6250 rpm. Even more radical than the M2 Competition, it does not lose weight. Production of the M2 CS is limited to 2200 units.
