With due respect to the "d" fellas, I too was in a dilemma and test drove both 520d and 520i constantly, even back to back before deciding on the latter. Despite the stronger initial torque well mated to the 8-spd transmission, ultimately I felt the 520i's power delivery to be more linear and more within my expectations in terms of comfort and flexibility. By the latter, I mean the ability to sustain acceleration beyond 4,000 rpms. The great thing about the Twin Scroll Turbo (which is not in the 520d) is how it doesn't run out of breath at higher rpms. This aspect in the 520i even betters the A6 2.0 TFSI which tends to go flat after 5,000 rpms. At least the A6 gets paddle shifters I think to drop a gear faster, sigh!
