So logic at Munich is comical. Here is how I imagine it playing out....
BMW marketing meeting "ok new idea. Lets take the 2 door three series and call it a 4 series? Brilliant, done!" "Oh and while we are on a role lets take the 2 door 6 series and also make it in a 4 door? Fantastic, make it so!!" "We will call it the 4 series 35 X drive IS active hybrid. It has a great ring to it!" Meeting adjourned.
BMW, why so crazy?
