RichReg:
I also stand as being corrected. I noticed that on the US web site for the new 5 series, thay are talking about, for the first time they have incorperated DI with the 335 turbo, so they now must have the ability to do both. The NA DI engines could actually be brought here now but they would not be able to run in the lean burn mode, and subsequently not take full advantage of the fuel economy benefits. In lean burn mode the exhaust tempertures are much higher and they must use low sulphur fuel.
