When something heavy needs to be hauled, nothing beats a diesel-powered pickup Truck. Of all the petroleum-based powerplants fitted to an automobile, the torque potential of a diesel engine is unrivaled. Here it might be useful to explain; while everyone gets so excited about horsepower, torque is the true expression of an engine’s pulling power. Torque sets a vehicle into motion; horsepower keeps it there once torque has done its job. Perusing these listings, you’ll note the best diesel trucks all post highly significant torque numbers, and further, the higher those torque numbers are the higher the posted towing and payload capacities will be. In other words, if you’re looking to do some heavy duty hauling, a diesel pickup is very likely what you need.
