I have posted photos of the engine in the first standard production coach with the new Cummins on my blog Drive Alpine. All coaches now in production use the new engine. Anecdotal feedback from the team that drove the test coach with the new engine to Arizona and back is that they did not "notice" any difference in mileage compared to the "old" engine.

There is also a photo of Bubba (my new coach) the day before it left production and moved to "prep". One of these days I might well actually own an Alpine. Then EAT MY DUST, TED.

Thanks for the pics. Norm!

Is this the new 425 hp Cummins?
Did they have any feedback on the noise levels of the diesel particulate filter and exhaust?
Also any feedback on vehicle acceleration/performance?

I hope you get an flawless coach soon!

Since their explanation is that the DPF works similarly to a catalytic converter-- I can't think of a reason it would affect noise levels-- but that was not discussed within my earshot.

The explanation on the horsepower factor for the 425 was that the net hp will be the same as the 400-- which would indicate to me the performance would be the same-- though I personally did not specifically ask that question.

When we were in Hilton Head the Cummins Rep indicated that the exhaust would be quite quiet. No more throaty sound. Performance was to be almost the same. So NORM, check the dust you may be eating. I am happy for you that it has come with an engine. You might have considered the new optional engine.

Ted: Actually, it did not come with an engine. Fortunately I found a coach out back awaiting delivery to a Dale & Dixie G..something, so we swiped that one and left a mule tied to the D&G unit (Will they ever be surprised this Wed.). Hay is cheaper than diesel and the "exhaust" can be used to produce ethanol-- so they should be OK.
