Two cars, both in the same small to medium size four-wheel drive category. Both cars offer their own advanced all-wheel drive system; the BMW X3 with xDrive, and the Audi Q5 with its Audi Quattro system. What's better?
Keep in mind both of the cars had traction control settings switched off as this was more of a test to distinguish the difference between the centre differential slip and overall four-wheel drive torque split capabilities.
The specially made four-wheel drive jig was also set up to place high demand on the front and then rear wheels, isolating the two under power.
Before Audi fans get too upset though, it's imperative that we mention this was a BMW promotion... and the ramp was setup by BMW. Still, it's interesting.
