From Truck Yeah!: The 2015 Ford F-250 Super Duty is aesthetically similar to its predecessors; but "she's got it where it counts." Sort of. New for this year is a revised version of the 6.7 Power Stroke diesel that cranks out an ass-haulin' 440 horsepower and 860 lb-ft of torque– all the juice you can buy in this class right now.
