The answer is three - 430PS, 440PS and 450PS.
Question is what is the point as the figures are all so close? Surely these engines all have a tolerance range of output in any case which confuses matters further with a healthy 440PS engine perhaps putting out more than a below par 450PS one?
They also make two versions of the 4.2 FWIW - 400PS and 405PS. Again why the difference and - more importantly - is there any difference really?
