The 6.2L is a HP BEAST coming in at over 400HP in stock trim(and can be tuned to MUCH more). Most of them are also backed up by the new 6 speed auto that is an all new design(6L80E that is an all clutch pack unit like most of your euro deigned trans now have). As for the AWD, I'm not real familiar with the newer systems. Some of the older ones still used a CAD in the front end, but I have been told the new ones got rid of it. I do know that front diff failures have become common place now at around 80K miles in the AWD units as many of the DENALI and ESCALADE people HATE THEM WITH A PASSION! The transfer case's are also a pretty oddball unit and require the special SMURF oil be run in them and changed every 15K miles IIRC. It uses a hydraulicly actuated but electronically triggered clutch system in them to fully engage the front differentail even though it spins whenever the AWD is active. It is a nice unit for those who can't remember to turn 4X4 on when it is needed, but I persoanally like being able to decide when to turn it on.
