No not that V12... but the one form the 760i is also rumoured.

Although I agree with you... the T-V8 is more likely.

More pics

That is bearing the looks of something that is ready to be released for the public.

I agree, but for a TT V8 or V10 i expect some different body kit too.

A TT V8 could be a replacement for the 4.8i X5 hence maintaining the same body style. With regards to the V10, I have my doubts about it in the X5 but probably in the X6.

I know there won't be X5 M...

But in any case that TT V8 will probably be top of the range so it must look muscular.

Isn't this the X6 V10 being tested rather than an X5 M model???

were the side skirt and body kit... i think this is more just engine and cooling testing

I really don't think the V10 will work for this monster ... it needs a higher torque figure to perform .. unless it has some sort of new transmission ... IMO of course

V8 TT is the way to go ..

Didn't Eni say that they are testing X6 M engine in X5. But how many X5s are they using to test the X6 engine.
