The BMW X4 came to be in 2014 as a coupe version of the popular X3. Although sporting a sloping roofline and a redesigned rear end, the X4 is actually an X3 underneath, using the same chassis and drivetrains. The purpose of this crossover was to offer customers a sportier looking X3, as well as expand the company’s SUV lineup to four models. Unlike most Bimmer, the X4 has yet to gain a proper M version, although BMW did launch an M40i for the 2016 model year. In 2017, rumors that an X4 M might be underway began to turn into reality with more prototypes spotted on public roads. Come 2018 and the first-ever M version of the crossover is getting closer and closer to its official debut.
