Why the lower HP/Torque in a CC - Dodge Diesel

Remudadoc · 10-19-2009, 06:57 AM

I have a brand new, 4500 with a custom hauler bed for pulling a large horse trailer. Why do the CC's have lower horsepower and torque than the 3/4 and one tons? That seems completely backwards to me.

I don't get that either. And to top it off when the new bodystyle comes out the chassis cab is rumored to have urea injectin where the 2500/3500 pickup versions dont. Why would the engine with the lower hp/tq rating need more emission equipment then the higher hp/tq version?

It is likely because of type of use the majority of these trucks get. A large percentage of them are probably used for fleets, and the focus there would be fuel economy not peak hp. And that type of use may also bring a lot more time spent idling, so that is probably the reason for the urea. With more idling, that would cause a lot of passive DPF problems. So a lower peak hp/tq and the addition of urea probably solves the economy and emissions issues for the fleet customers, and other customers can still use the trucks without problems. I'm considering a 4500 for towing a heavy gooseneck, so while I'm frustrated with the two things mentioned in this thread (lower peak output and urea), I think I understand why.

The 2010 C&C will have urea beacuse of the extended idleing of some fleet trucks especially in cold weather. The lower rating is for reliability and better emissions, the C&C exhaust system is very much different that the pickup and has had less problems.

The reason for this is because cab and chassis trucks are marketed as commercial vehicles, which causes them to fall under different epa regulations than private use vehicles.
