BMW came out with the official press-release for the 2007 X5 -unfortunately it's not available in English yet. It seems my information on the diesel engine was "one turbo wrong" as the X5 gets the normal 231 Hp 3.0 AND NOT the 272 Hp twin-turbo 3.0 6cylinder -although it is certain that the X5 will get this engine later. Also, the 4.7 V8 pumps out 355 Hp (and not 367 Hp) while the 3.0 petrol is good for 272 Hp (and not 265 Hp).
