Fully agree. I just don't get the often narrow minded view that diesel = towing. In fact...it doesn't. It usually means torquey and uber fuel efficient and IMO the V6 TDI is just the best road going diesel of all time. Just because its a diesel doesn't mean its built to be a Peterbuilt.You have to be realistic and have realistic performance\towing expectations about what you are using, for what purpose.
The V6 had sufficient grunt for light towing, and plenty for moving the "pig" that is the Touareg.
Clearly, if you add a massive wind brake to the existing pig, or another pig that's just as heavy or heavier, your experience will deteriorate.
For weekend\occasional towing of some toys or a TT, it's sufficient and acceptable. If you're doing full time heavy\big loads, then you could definitely use something with +35-50% the TQ. Given the capability and MPGs that it delivers, it is my opinion that it's a very well suited engine for the vehicle that it resides in.....
You need to use the right tool for the right job.... if you need to tow big, get a dually and throw the MPGs out the window.
Reminds me of the opposite view when the V6 hybrid was released and most thought it was the slow eco version...when in fact it was a flat out hot rod.
