Sometimes it can be turbulence caused by airflow from stuff like mud-flaps, the air deflectors in front of the wheels vibrating, or the airdam etc. You could try putting 'gaffer' tape vertically across these surfaces and see if it changes the sound.

^^^^ should have added... at the speeds you mentioned it could be that a wheel is very slightly out of axial balance - check and see if a weights come off. |

I have now done another 500 km to Austria and can report the following. The droning noise occurs between 70-90 mph but ceases thereafter. There are no other observations such as steering judder or judder under breaking etc. I drove long stretches flat out 140/150 mph and the car was rock solid. A real revaluation. The engine is superb and makes a wonderful noise at full throttle. There is an awful warning sound coming up when you hit the top speed limiter at 150 mph so you don't want to hot that too often.

Took their other same spec as mine out today and it made the same noise. So it's not just mine.

Yes, they did say it only seems to happen on the ones with the 22" wheels.

My AB is the SDV6, and the tyre noise on 22" wheels is quite acceptable, but as I have mentioned before on the coarse tarmac with the chippings, then you do hear some noise, but on smooth tarmac it is really ok. Yesterday I had an 80 mile round trip on the motorway at speeds of 70 ish and then maybe a little more, but there was no increase in tyre noise in that band. Several years ago I had an Audi Estate with 35 profile tyres and the tyre noise was awful so much that I couldn't wait to get rid!

My advice would be to go for the 21" wheels. Which is a shame as they look the on the 22"s i think.
