Wholesome competitors lowers the worth of client items, the economists inform us, nevertheless it additionally raises torque rankings. Nowhere is that this extra obvious than among the many Detroit Three automakers, with Ford, Common Motors and Fiat Chrysler Cars locking horns, crossing swords (preserve it clear…), and firing arrows at one another in a heavy-duty pickup conflict that’s solely heated up lately.
It comes all the way down to stump-pulling, gravel-hauling, trailer-towing twist. In 2015, the Ram 3500’s 6.7-liter Cummins inline-six turbodiesel topped the Ford F-350 SuperDuty’s 6.7-liter turbodiesel V8 by 5 lb-ft of torque — 865 to Ford’s 860. This clearly couldn’t stand, so for 2017 Ford upgraded the Energy Stroke’s torque score to 925 lb-ft, kiboshing Ram’s 2016 try to remain forward with a 900 lb-ft score.
With 2017 got here additional aggressions. This 12 months noticed GM pulling forward to second place with its 6.6-liter Duramax V8, now upgraded to 910 lb-ft, knocking Ram down to 3rd place.
Nicely, FCA’s having none of it. Only a day after Ford’s unveiling of a newly highly effective second-generation 2.7-liter EcoBoost V6 and 5.Zero-liter V8, Ram fires this salvo: a Cummins with extra grunt than another rival.
Introduced this morning, the Cummins-equipped 2018 Ram 3500 Heavy Responsibility once more tops Ford’s finest effort by 5 lb-ft, now making 930 lb-ft. Horsepower stays unchanged at 385, lower than Ford’s 440 and GM’s 445.
FCA claims the additional twist permits house owners of the most important fifth-wheel trailers the choice of avoiding Class four or 5 autos for tow responsibility. Utilizing a brand new hitch design engineered by Ram, the automaker guarantees 30,000 kilos of fifth-wheel towing capacity. In distinction, the Ford F-350’s fifth-wheel hitch can solely deal with a most of 27,500 kilos. A GMC Sierra 3500 HD tops out at 22,700 kilos.
Utilizing a gooseneck or standard hitch, the diesel HD Ram’s most trailer weight rankings stand at 31,210 kilos and 20,000 kilos, respectively. Sadly for FCA, Ford’s F-350 beats these numbers by a hair.
FCA achieves the additional 30 lb-ft of torque by means of extra air and extra gas arriving within the straight-six’s combustion chambers on the identical time. Go determine. Cummins ratcheted up the engine’s enhance limits by means of a variable geometry turbocharger, rising the gas circulation charge on the identical time.
Not all the things is thought but about this engine, so we’ll assume a carryover of the six-speed Aisin computerized. Whether or not gas economic system adjustments in any respect stays unknown, although patrons of tow vehicles for ultra-heavy trailers often don’t put fuel mileage on the prime of their checklist of considerations.
