[urq] Future Audi : is there a TDI planned ?

[Cody Forbes]

Valid point. Having no personal interest  in buy a brand new car ever I wasn't aware of the large entry fee. Buy one used and the economics get better. Also larger platforms that are thirstier tend to have a greater advantage from diesel I believe, ie a ~40mpg FSI Jetta becomes a ~50mpg TDI, but a 20mpg A8 FSI becomes a >40mpg TDI (according to Clarkson).

So you would have to drive 266,000 miles to make up the diesel premium!  That's assuming you pay cash for the car, not finance it.  That's a long payoff for a high upfront investment in diesel.
