One question that would need to be answered. Particularly for the 0-60 time is did the lower geared truck need to shift an extra gear? Or as another mentioned traction could also be an issue.
Also, difficult to compare as these were done 4 years apart. Could simply be different shifting algorithms, weather, track condition, etc.
"Both times an F250 with the 6.2L V8 gas engine was tested. In the 2010 Shootout, they used a 2011 model, and in 2014, they used a 2014 model. Both were rated at the same 385hp/405tq."
