They could have kept 550nm all the way to 6500rpm to have the manual make 375kw from 6500rpm to 7200rpm like the 8AT, that would have been a lot of fun I think. What is also interesting is the power drop off showing on the 6MT once you get to 7000rpm whereas the 8AT holds power to 7200rpm (which makes NO sense)
Details in the specs page, the M3 power and torque curve is for the 6MT, the M4 is the 8AT
