New X5 G05 Xdrive5.0i by specs is heavier than predecessors F15 and E70 with the same engine N63B44. It has 650N/m torque and 462 hp and specified acceleration 0-100 km/h is 4.7 sec.
Against E70 X5M with engine S63B44O0 and 555 hp and torque 680 and WITH THE SAME acceleration 4.7 seconds ???? G05 is not lighter than X5M E70.
How it can be ? Anybody can explain how 462 hp accelerates equally to 555 hp basically with the same engine, with less torque and with almost equal weight ?
