Why do people think that this car will have more than 555 PS? The X5/6 M engine is complete and they are not going to modify it just for this car and the M6. The M5 will already have an advantage over these two hulks with respect to mass to power ratio and the addition of a superior 7 speed, 2 clutch gearbox. Look at the upcoming 1M- probably will have the 335is/Z4 sDrive35is/740i/Li engine in it, no changes. And that will be good enough for ///M status.
