This is America damn it . . there is no longer any such thing as personal repsonsibility. It is always someone/something else's fault!
back to shit that matters:

The M offers the same utility as the regular X5, with the addition of a twin-turbocharged 4.4-litre V8 delivering 413kW at 5 750r/min and peak torque is 679Nm, available between 1 500 and 5 650r/min. BMW claim their X5 M can sprint from a standstill to 100km/h in 4.7 seconds.
The X5 M and the new X6 M are the first xDrive all-wheel-drive vehicles from BMW to sport the “M” badge. Coupled with special “M” air suspension featuring Adaptive Drive and the newly developed Servotronic power steering, the performance SUV promises very competent handling. Other high-tech features include launch control for maximum acceleration and an “M” six-speed automatic optimized for performance. Drivers can manually select gears using either paddles or an an electronic gear selector lever.
Electronically controlled, variable power distribution to the front and rear axle prevents even the slightest tendency to over- or understeer, before DSC Dynamic Stability Control is required to cut in.
BMW is referring to the new 4.4-litre motor as its “M TwinPower Turbo” unit. The name reflects the fact that the motor features Twin Scroll Twin Turbo Technology and a common exhaust manifold encompassing both rows of cylinders.
Although traction control is standard, the M Dynamic Mode (MDM) greatly reduces the aggressiveness of the system. The MDM setting allows the driver to enter a controlled drift and push the vehicle’s handling to the limit. There’s also a DSC-Off Mode for drivers seeking a more purist experience.
