Diesel pickup trucks have never been more popular than they are today and the trend is accelerating, for all the right reasons. Diesel engines deliver more torque and higher levels of fuel efficiency than gasoline engines. The most potent diesel engines now produce over 900 mind-boggling pound-feet of torque and the most efficient are capable of 30 miles per gallon on the highway.
Our list of the ten most powerful diesel pickup trucks runs the gamut from mid-size rock crawlers through jumbo sized duallys designed to make the long haul. While the United States Environmental Protection Agency (EPA) publishes fuel economy data on half-ton pickups, manufacturers are not required to release similar information for larger trucks.
