As you possible know, the gearbox is a six-speed handbook and will probably be fitted to the common M3 and M4 fashions whereas the Competitors variations will characteristic an eight-speed automated. The handbook retains an H-pattern and now means that you can swap automated rev-matching on or off as you favor, no matter which drive mode the automobile is in. To maximise stiffness and shift precision, the gearbox is doubly hooked up to the physique. Karsten believes that BMW has the most effective handbook gearboxes out there, and has determined towards optimizing the system any additional past the aforementioned stiffening. We’ll must drive the automobiles to see if Karsten is true, however our personal expertise with BMW manuals has been iffy for essentially the most half, so we hope this elevated rigidity improves the way in which it feels.
