A8 D3 Sport - 3.0 or 4.2 TDI?

[M5Sime]

Hi all,

Does anyone have opinions on the merits/pro's/con's of the two diesel engines..

Clearly the mpg is similar, the V8 is more powerful and is heavier in the nose...

What in the real-world is the best engine for the A8? Does the V6 3.0 feel a little underdone?

Model year would be circa 2006/7 likely.. I think they tweaked the 3.0 V6 and I know the 4.0 TDI moved to the 4.2..

Any other general advice on these superb cars (Warranties, running costs etc)

Cheers

Thanks guys!

Both of you are advocating the remapped V6 then, over the V8. So the standard product is not that sufficient?

The V8 official MPG is not that far off that of the V6 (and has so much more power). Thanks for the tip on the 4.0 v8. I was not planning to go for this one

Hi UKDennis,

Thanks for the comments! Have you tried the 4.2 V8?

Have you heard the Bose vs the B&O? I managed to find a youtube clip of the 5th gear test (crap) where they tested the two (well sort of).

Any other pearls of wisdom you can share?

Cheers

Hi Chaps,

What about the topic of warranties and general care and attention with these beasts!

Any must have options?

All in all, supreme motorway vehicle that is nimble on the twisty bits. Good economy and performance, understated absolute luxury.

Thanks for the info and description! I even see that some of them have Sky Digital TV with a small receiver on the boot lid I guess (or was this just the D2s)...

I am definitely not being put off by any of the comments fo far! :-))

I still get 28mpg out of mine on the motorway consistently doing 85 leptons per hour.

Hi.... And you have the 4.2 V8 Petrol? or the TDi and get 28mpg..

I plan to drive it briskly for 110 miles of motorway and some A roads each weekday... Are the official figures of 30 and 33 mpg for the V8 and V6 diesels respectively achievable?

Thanks

Thank you all for the comments in this thread! Certainly does help. seems the V6 TDi is the most parsimonious, but the V8 TDi the most tempting :-))

I wonder if these need a remap to deliver better economy?
