FCA’s Ram Truck division has revealed that the brand’s 2016 model year Ram HD will feature an upgraded 6.7L Cummins turbodiesel producing a peak 900 lb-ft of torque – an increase of 35 lb-ft, distancing Ram’s closest competitor by 40 lb-ft. Rated horsepower, for now, remains unaffected.
In addition to the added muscle, the Ram 3500 will be available with up to a 39,100 lbs. GCWR and a maximum tow rating of 31,210 lbs, an increase of 1,210 lbs over the 2015 model. To sweeten the pot, Ram Truck’s entire line of pickups (1500, 2500, 3500) have tow ratings substantiated by the SAE’s J2807 standards and the 6.7L Cummins will continue to be covered under a 5 year, 100,000 mile warranty.
You may recall that Ram’s current diesel lineup is tiered, with the most powerful of three Cummins engine options available only in the Ram 3500. There’s been no comment on whether or not the 900 lb-ft Cummins will become standard, or if it will remain a High Output option reserved for 1 ton pickups. It will undoubtedly be mated to the Aisin six speed automatic transmission.
Squeezing more performance from the 6.7L Cummins was accomplished through recalibration of the engine, specifically targeting fuel delivery and turbocharger boost. In order to maintain reliability and durability in the new configuration, the 11.8” rear axle was revised. Engineer’s increased the ring gear’s bolt count from 12 to 16 in addition to using hardened bolts and stronger materials all around.
Heavy duty pickup models from both General Motors and Ford Motor Company are expected to undergo serious changes in the near future. In particular, GM is rumored to be working on their 6.6L Duramax, which many believe has become dated – the 397 horsepower, 765 lb-ft torque engine received its last major upgrade for the 2011 model year. Meanwhile, the engineers at Ford are hard at work on an aluminum bodied Super Duty.
FCA reports that production of 2016 model year pickups will begin in the 3rd quarter of 2015, while they are expected to hit dealer lots in the 4th quarter of 2015.
