Now that I put 1000 miles on my new to me TDi, I can start reporting to those of you who were curious about comparison of small CRD engine to another small, consumer engine from VW.
1. V10 is a bit easier to spin up and feels more like gas engine, however it has more typical diesel truck turbo whistle and more corny blow off, when I drop the pedal.
2. V10 seem to generate more oil from CCV, especially on the right bank, probably due to the CV engine rotation.
3. CRD is more economical in the city, about 20.5 mpg solid, however low gear ratio of Jeep kills it on highway, where V10 is climbing up to 25mpg at 75mph. I just came back from 200 mile trip with 2000 lb trailer on the back and ended up with 19.5 mpg at 70 mph. So, if someone wants to re-gear to 3.07 (from 3.7L version), 28mpg+ on highway are awaiting you
4. V10 is a lot more simple engine, 2v/cyl, single cam (however with some kind of VTEC to it), all gear driven, cam driven injectors (no piezo BS), no individual, deep down there butterfly valves and such... CRD is a bit over engineered, but cheaper to maintain, with no freakishly, rear mounted accessories that require engine pull for new starter and such.
Overall, I have to say that even though I am happy with Touareg, Jeep CRD is still a pure jewel for the money.
