What stood out in 2004
Editorial opinion, based on the criteria listed.
Pick: Dodge Ram 2500/3500 with the ISB Cummins (325 hp / 600 lb-ft)
Runner-up: Chevrolet Silverado / GMC Sierra 2500HD/3500 with the Duramax LLY (310 hp / 605 lb-ft, from mid-2004)
The Cummins 600 (325 hp / 600 lb-ft, introduced mid-year; earlier 2004 trucks were 305 hp / 555 lb-ft) matched Ford's 325 hp and led its 560 lb-ft by 40, and it came within 5 lb-ft of the new LLY's 605 while beating it by 15 hp. Weighing both measures together, it edges the LLY, but a torque-first reading would favor GM. Editorial pick; a close call.
Criteria: Peak rated torque; Rated horsepower
