Lot of erroneous information in this thread, just thought I wouldpick out this one piece of info. The Diesels definitely are sold with QD II.
Quadra-Drive II QD @ is sold on the diesel. As for the idea that they can't spin the wheels, the torque figures for the V6 diesel are very similar to the Hemi. Only the SRT 6.1 liter has more torque. 420 to 376.
