Follow-up review after 2K miles
 Driving in about 4 inches of unpaved snow, slush and ice: In straight lines it accelerates and stops under complete control. To test out the traction around corners, I took a couple turns at relatively unsafe speeds, close to 15 MPH. The DTS flickered and appeared to do something, but it definitely felt like I drifted out of my lane.  During sensible speeds, drifting was not an issue. Slight hesitance may be confused with skidding, but its actually DTS doing its thing to keep you on your intended path. X-drive is very capable. However, I honestly feel Subaru sets the bar when it comes to AWD technology.  Basically if you're looking for a luxury AWD coupé, look no further.
