The S60R uses a 2.5L I5 motor since at least 2004, as does the current S40, and even the new 2012 Volvo S60R T5.
Although you are wrong on just about everything you said, I will agree with you on Ford not making the 2.5L I5 in the Volvo. The T5 engine, to the best of my limited knowledge on the engine, is not the same as the Duratec I5 in the Focus RS.
