Runs well. Very smooth and quiet. Wall of torque down low when cruising so engine doesn't downshift much. When floored it punches hard, possibly Volvo's best engine, worlds better than the high output version of the 2.5T in my old V70R.
The haldex is fine for a slip and grip system. Don't see any slip before gripping. Again the 5th gen system is better than what was in the V70R (third gen)
