Looking at between a 3500 and 5500 Ram and would like to get a 5th gen body style. Wondering when they are going to release the new tin.
Love my 2016 Ram 2500.Looking at between a 3500 and 5500 Ram and would like to get a 5th gen body style. Wondering when they are going to release the new tin.

I dont think its far fetcheched to see the end of the Ram/Cummins relationship.
Ram dont need them like they did in the past. Fiat is capable of building a diesel engine just like they dis for the 1500 series.
errmmm.... The Fiat (FPT, Fiat Power Train, formerly Iveco, Industrial Vehicle Company) 6.7 liter used in Case and New Holland tractors, is built with the tooling bought by Fiat from Case IH when the old IH plant in Neuss am Rhein, Germany, was closed and Maxxum production moved to Doncaster, GB with engines built by Cummins UK instead of by Case IH.
Fiat and Cummins had a joint venture on this engine, after an earlier deal between Fiat and Nissan to replace Fiats aging small truck engines, didnt yield result before the 1996 TIER 1 emission stage. The Iveco Tector 5.9 engines used in the EuroCargo trucks were identical to Cummins 6BT5.9
Later, when Case was sold to Fiat subsidiary New Holland, Fiat stopped paying royalties to Cummins because they now owned Cases share in the Consolidated Diesel Corporation, the Case-Cummins joint venture that developed and built the B and C series Cummins engines. Cummins was pissed off about this and patented all modifications done to the 5,9 to make it a 6,7 (look up Google Patents: many Cummins patents seem totally pointless because they specifically apply to -modifications- to the B series engine design: pointless, unless you know Fiat also owns the rights to the original B series design through Case IH) so the Cummins engine had its bore and stroke enlarged from 102x120mm to 106x124mm, where the Fiat version of the same block, had 104x132mm bore and stroke.
Although i dislike Fiat products for their shabby plastic parts and electronics (New Holland tractors, Iveco trucks) i like their 6.7 over the Cummins, only because of the emission strategy: FPT uses just clean air, no EGR nor DPF, just DEF. And because t breathes clean air, they can do the same power and even better transient response, with just a wastegated turbo, and no variable turbo.
Caterpillar Marine also has a joint venture with FPT for this engine, the 500hp versions for powerboats, Cat cannot get that much power from a Perkins based 7.2 liter engine with their EGR/DPF based emission technology. Instead they rebadge FPT marine engines, which do it much easier by not cramming exhaust gas back into that little (for the power) engine, rated at 500hp at 3000rpm.
So short said, Fiat replaced the Cummins in the Case tractor line with their own extrapolation of the original Case/Cummins B series engine, and undoubtedly when the spirits are ripe, the Ram truck will also get its Cummins replaced by a Fiat built B series engine...
