What stood out in 2021
Editorial opinion, based on the criteria listed.
Pick: Ford F-250/F-350 Super Duty with the 6.7L Power Stroke (475 hp / 1,050 lb-ft)
Runner-up: Ram 2500/3500 with the high-output 6.7L Cummins (420 hp / 1,075 lb-ft)
Ford led on horsepower by 55 hp; Ram's high-output Cummins led on torque by 25 lb-ft. GM's L5P was rated 445 hp / 910 lb-ft. Weighing both measures together, Ford edges it. The year Ram's 420 hp rating began is not confirmed. Editorial pick; a close call. Ratings shown are the highest offered; other trims are rated lower.
Criteria: Peak rated torque; Rated horsepower
