Really? The conversation was about an M3 with 550-600 pound feet of torque? Must've missed that.
The GTS makes about ten percent more torque than the standard M3, peaking at a slightly lower rpm. In my opinion, if this engine were in the M3 there would be no more talk about a soft low end.
Given the car's other attributes, the 4.4 liter power plant would address one of the car's (very minor, IMO) weaknesses. It would liven up the lower end considerably. It might even address the car's only other (more major) weakness, which is fuel economy. With more torque available, you could go for a more aggressive overdrive in top gear, as Porsche has recently done, and thus improve highway mileage thru reduced pumping losses and friction.
It's terrific now, but with the 4.4 and gearing changes it could in fact be the almost perfect car - closer than anyone has gotten before.
