Drove the 2013 A4 based Allroad last week. While the platform was very nice, I found the car a bit heavy and the 2.0T coupled to the 7-spd auto trans a bit of a letdown. Off the line performance was plagued with turbo-lag until the turbo spooled up, and then WOOSH! Same for uphill passes, each accompanied by a downshift and more WOOSH! Other than the turbo-lag though, it was a nice driver.
Having a bit of torque a-la TDI would be nice.
Audi should've put the 3 liter supercharged engine (thats in the S4, S5, A7 etc) in the Allroad. The 3.0 is a fabulous powerplant, largely unaffected by altitude with gobs of torque down low and no lag, and decent gas mileage.
