I can attest to that, though not apples-apples comparison as I have a wagon. Neighbor has a B6 FWD Passat while I have a B6 4-Motion. He is considerably faster (aside from my initial launch benefit). Additional weight and drivetrain losses certainly show.Side note, met a dude at RDM with a stanced b6 4motion 3.6 and we lined up quite a few times just for fun and i always beat him. The 4mo is like 600lbs heavier or something
