Earlier in 2017, we saw BMW launch a new limited-edition M4. It’s called the CS and slots between the standard M4 and the track-ready GTS. Essentially a GTS without the massive wing, the CS also marked the return of the famous badge that BMW used in the 1960s and 1970s. Not surprisingly, the M4 CS was very popular with BMW enthusiasts, which is why the German brand is also considering a sedan version. Naturally, it will be called the M3 CS.
