The answer? No. Why? Because BMW does not want to hurt the lucrative pie that is the X6 M. BMW product communications manager Bernhard Ederer stated, “The question is what customers are we talking to? And are we talking to someone that is [currently] willing and able to afford [an X6M]?”
BimmerBoost can see Ederer's point but at the same time the whole reason for the X4 existing in the first place is because the X6 is a success. Would the same logic about chewing into X6 sales not follow with the X4's existence in the place? Furthermore, why even build an M4 if the customers can opt for an M6?
Obviously the M3/M4 despite being less powerful are lighter and more fun to drive. That is exactly what an X4 M would be. The argument is practice just does not hold up with the X4 existing in the first place. Additionally, with how heavy the BMW X6 is the X4 honestly makes more sense as an M model and would be more affordable.
Rather than looking at it as X6 M sales being lost BMW should look at it as having a better example of an M SUV in an X4 M with new sales gained. Also, BMW would then have an answer for the Audi RS Q3 and upcoming Mercedes GLA45 AMG. Do not rule out an X4 M just yet especially if X4 sales take off.
