With a best-in-class performance, the 2021 Ram 3500 is hard to beat in terms of diesel output. While the 2021 Sierra 3500 puts up a decent fight, it doesn't hold a candle to this beast. Growling under the hood of the Ram 3500 is a 6.7-litre H.O. turbo-diesel I-6 motor mated with a 6-speed automatic transmission. Showcasing brute strength, this unit can generate 420 hp and a jaw-dropping 1,075 lb-ft of torque. With the proper equipment, it can even pull 16,828 kgs (37,100 lbs) with ease. On the other hand, the Sierra 3500 is fitted with a 6.6-litre turbo-diesel V8 that makes 445 hp and only 910 lb-ft of torque. Paired with a 10-speed Allison automatic transmission, its maximum towing limit with a gooseneck attachment is about 7,443 kgs (16,410 lbs). That is nowhere near the monstrous Ram.
