That is what Autocar says. The car is still very good and exciting, but it is more about acceleration and torque now. The problem is when you want that final edge when pushing it that the old M cars would deliver as you wound them out toward redline and whipped them into a corner, braking then executing a perfect downshift with instant throttle response, the new cars just don't deliver.
The reviewed states we have lost a bit of nimbleness and excitement in favor of a more everyday usable experience. This all coming from a female reviewer in the video by the way. She does state it likely will only be the M Purist who cares. She likely is correct.
