I drove my AWD XTS and my wife's FWD Impala on some very slick surfaces today. The Impy was wheel spinning and traction control while the Caddy just moved out with barely a complaint even uphill from a stop. That Haldex unit is just amazing and I'm sold on AWD, in this part of the country anyway. Of course stopping in both resulted in about the same amount of anti-lock chattering.
