Correct, and my point wasn't that it couln't be done. My poitn was that it might de delayed while they figure out how to shoehorn an oil cooler into the existing X5 layout... assuming that the new X6 might have one already designed-in.

I don't know, but am merely speculating.

Doesn't anyone know if the X6 twin turbo engine has an oil cooler?
