Ok, I think we need to clarify the use of the term "TDI" in this thread.
The one I think of is the 1.9 L engine in the VW sedans that gets close to 50 mpg. I think some folks are using the same term to refer to the high performance diesel in the Tourag, which is a totally different thing, right?
Hmm, I just checked the vw site, the only engine option they show for the Tourag is a V-8, I assume this is what other posters meant about the diesel Tourag being very scarce?
