IMHO, I have found the 1.9 TD to be MORE economical than the CS that it replaced. Although its cylinder capacity is larger so it uses more fuel per stroke, it can generate the same power at lower revs and throttle openings compared with the CS. Moreover, it has a turbo and the CS doesn't; the turbo basically squeezes a load more air into the system, leading to a leaner burn and greater efficiency.
It's a subjective thing and affected by many variables, but I seem to be visiting filling stations a lot LESS frequently with my AAZ than I did when I was doing similar journeys driving the glorified sewing machine that was the CS. Without having figures to back it up, I think the AAZ is more economical but even if it isn't, you are not going to suffer noticeably increased fuel bills.
A lot depends on how you drive, too, of course...
