Interesting competition. It looks like the 6.0 put out the best stock time with the D-Max not far behind, although it states the PSD was run later in the day with a headwind, which would explain it's slightly lower speed. It seems that all the Big 3 Diesels are fairly well matched against each other, with the Cummins having more grunt down low, and the PSD and DMAX being better highway pullers. I agree though that it isn't very real world, but a good article still.
