Whats the X5, power ratio between front and rear ?
 

For example, when accelerating is the power split evenly between the front /rear wheels in a perfect 50/50 ratio.



I thought BMWs were more rear-wheel favored cars , yet wondering how BMW implemented the 4WD system on the e70?

not sure. isnt each axle operates independently? so whichever wheel has the most traction gets more power?

The standard drive distribution for the E70 on high-traction surfaces is 40% to the front and 60% to the rear. Away from normal operating conditions, and depending on available traction, throttle input, steer angle, etc, the X-Drive system can distribute the drive front to rear as it sees fit - up to 100 percent either way.
