Versus Diesel Comparison By Brand - 7% Grade with Trailer
an opportunity to compare the relative performance of the single rear
wheel gas pickups against their dual rear wheel diesel counterparts
on the 7% grade.
not an apples to apples comparison (primarily because of weight and
rear axle and rear track differences between the 3/4-ton and 1-tons),
but it provides some indication of the scenarios where each type of
engine excels. You can see the patterns from manufacturer to manufacturer
are almost identical, regardless of the truck / engine / transmission
as we noted during the level 1/4-miles at Milan and MPG, look at how
close the time and speed curves are for the Ford trucks. They were
near identical up the 7% grade. In contrast to the Dodge and GM oil
burners, the 6.8-liter V10 gas engine was faster moving up the grade
than the 6.4-liter V8 diesel.
