w/o knowing much about the tech aspects of the EDGE's AWD system and what it should do and what it shouldn't do, I'll do a comparison.
I currently own and have driven Audi quattro in some shape, form or fashion for the last 13 years, prior to that, a shit load of VW (irrelevant). Now when I say drive, I mean, I have flogged the living he'll out of quattro haldex system and completely know the limits or lack there of, Audi's awd . So, after purchasing 2015 Edge Sport, I was skeptical, and declared it an inferior AWD system prior to even driving the thing.
So saying that to say this:
Thus far, I havent had much time in the snow, but I have had a chance to drive the EDGE in heavy rainfall, a few weeks back, in Hurricane Patricia remnants within the Chicago area. Im happy to report that I am completely floored by the performance of the AWD system on the EDGE. During heavy rainfall, monsoon downpour for hours, with heavy standing water on the highway, (*Luckily I was past the point of break-in) I was able to lay into the EDGE. 80-100 mph sprints, high speed long sweeping turns, quick turns, sudden breaking, you name it, I scenario tested it. There was at no point traction control taking over and applying ABS to any of the wheels, as the system never detected excessive wheel slippage or loss of control. There is one particular corner, about a half mile long wide right, full of water, 5 lanes wide and no traffic, I am always able to get the quattro to slip and jump a lane or two at the apex but this EDGE, ate it up and wanted more, dove right into the apex and hung on, even mid turn, I goosed the twin turbos and it just kept minding its own business like it was a sunny sunday afternoon.
Now, I dont condone driving like a maniac, but hey, its Chicago But I had to understand the limits and what should be expected from a performance aspect when these features will be used to avoid/prevent an accident with me and/or the family in tow. All in all, I am very impressed, I was reluctant to buy a minivanish type grocery getter, thinking the EDGE Sport could compare to the Q5, and quite happily it has, and in my opinion looks a whole helluva lot better doing so
