Introduced in 2013, the 4 Series is one of the company’s newest nameplates and marked the end of the 3 Series Coupe, which it replaced in the brand’s catalog. The renamed two-door also adopted a new, evolutionary design inside and out, and received a lineup of brand-new and revised engines. The high-performance version was also rebadged from the M3 Coupe to the M4 and ditched the naturally aspirated V-8 engine for a turbocharged, inline-six powerplant. The M4 also brought the GTS badge back into showrooms in the form of a more powerful, track-focused, limited edition model. In 2017, the German brand launched yet another limited-edition, high-performance variant, the M4 CS.
