Having driven a GMC Sierra 2500 the majority of the 1200 miles round trip between my home and Michigan over my Christmas "vacation" I can say that the Duramax diesel (particularly when mated to an Allison transmission) is an incredible beast of a machine (long story).

In fact, the Duramax should have eaten up the VW TDI and spit it out in little pieces, however, I think this video is more a sermon on the advantages of being able to maintain traction than anything else, but still...VW FTW
