The N52 gives 240 HP instead of 260 HP in the previous platform. How is this increased quickness possible, especially with the increased 2011 X3 dimensions, i.e. length, width, etc?
Easy it has more torque at a lower RPM, 230 vs 225 and tuned for a broader torque spec. Plus the 8 speed Gear box.

0-60 Torque and gearing is what matters. The old X3 might accelerate better from 100+ where you need the extra HP to overcome aerodynamic drag. However if the new X3 is significantly more aero the new one might still win.
