Larry,

You probably already know this, but I wanted to point out that the critical spec on the engine is the torque spec. It will tell you more about the drivability of the coach than the horsepower spec. My cat C-12 is rated at 1550 lbs-ft of torque and (Im told) is rated at 505 HP. I have heard of other C-12 engines rated at 320HP. Same engine with different software. In some of the newer coaches the C-15 cat produces 2050 lbs-ft of torque.

I found a short article about torque vs. hp. http://www.rvtechlibrary.com/engine/power.php

Others may want to jump in here..but the bottom line is that I have never heard anyone say that their coach was underpowered. (Cat, Cummins, DD) They all will push your bus down the road.

Find a Newell at the right-price point and you will probably learn to love your engine whatever its color (Blue, Yellow or Red).

Hi Bill,

Yes...I fully agree with your point regarding torque and have been trying to find the HP/torque specs for the different engines that Newell has offered over the years. I have found HP info but haven't come across torque values yet.

I have experience with all 3 diesel manufacturers (albeit marine service) and my only comment would be that DDs have always seemed to be leakers...maybe not an issue for OTR. This is not something that would make me rule out a DD however.
