Here is a video of the 2014 Acura RLX with Precision All-Wheel Steer (PAWS) on an autocross style course that was set up at Sonoma Raceway. See PAWS in action and compare side by side with a 2013 BMW 535i.
from observing the results of this video the Acura RLX PAWS system seems to work very impressively around turns. You can see the differences at the "turn ins". The rear kind of gives out to alleviate from over steer and carves in to the turn.
