Having owned a pretty modified 135i, I know what torque is. The N54 certainly snaps your neck on acceleration, but you never knew when it was going to happen. Plant foot... wait... Boom! The 1M has a lot of this same latency problem from the few times I've driven those at driving events.
So, there's torgue there, but it's fairly uncivilized. The S65 feels much more precise and direct in comparison. When I first got this car, the comparable lack of torque was noticeable, but the throttle response and precision feel won my heart. I just have to shift more, which I am very okay with.
My next car will likely not be a BMW, if the M4 suffers any lag at all. I'm not sold on FI on smaller displacement engines.
