He does a lot of miles, but not that many miles. Even if he were to get a 4x4 V8 and try to make up a 5k difference, it would be 210k miles to do so. Note that both of those calculations are using 89 octane fuel, if you use regular in the calculation it goes into the millions of miles for the v6, and 300k+ for the v8.
Not quite sure how you are doing your math.
I did some quick number crunching.
The current 3.0L CRD available in the EU and Oceana is rated at 23 City/33 Highway with a combined cycle rating of 28MPG.
The V6 (currently available everywhere) is rated at 16 City/23 Highway with a combined cycle of 19MPG.
The V8 is rated at 13 City/20 Highway with a combined cycle of 15MPG.
Fuel prices in the area near me are currently $3.97/Gal of Regular Unleaded and $4.49/Gal of Diesel.
With all of these assumptions I cranked out the following:
Annual Fuel estimated costs (20k miles per year):
I'd expect the CRD engine to be in line, pricewise with the V8 Hemi option (around $2,200). With that in mind, the CRD would pay for itself in about a year.
Diesel in general runs around 10-15% more per gallon than Regular Unleaded, however, a Diesel engine typically runs 30+% more efficient than a like petrol based engine.
To actually wipe out the efficiency difference in my example, Diesel would have to cost upwards of $5.15 per gallon (more so on the CRD as it's running 32% more efficient than the V6 and 46% more efficient than the V8 on the combined cycle).
So, again, not sure where you came up with 600,000+ miles, maybe the Touareg gets utterly horrid MPG... dunno.
