What is really interesting about the QQ-Sportage video is when a front and a rear tire is slipping at the same time. The Sportage must have an open front and open rear differential. Even when the Sportage AWD is locked and sending torque equally between front and back axles, all the power ends up going to the tire with no traction, so the car goes nowhere. In the case of the QQ, the power is being sent to the tire with traction. This can be done mechanically by a limited slip differential under a traditional 4x4s. I assume that Nissan must be doing it electronically which ties in with the Intelligent Trace/Ride Control. Not bad for an affordable cross-over.
