 I have ordered a 2018 X3 but decided to switch to the 2018 Q5 during last minute.   It was a 3 year lease.   The pro. Better cabin material,  technology was very advance, cabin noise is low during cruising, car handing was good, technology is not intuitive.The Bad.ABS activation at 24/25 MPH produce 2-3 clicks that driver can feel thru the gas pedal and can be heard by passenger.  Pre-sense is way too sensitive for NYC.  On numerous occasions,  while parallel parking.  The car breaks itself for no reason.  I was going less than 5 MPH with absolutely nothing behind or on the side.   This wouldn't be a problem if it can be permanently disabled but this requires going thru the 5-6 steps in the menu system to disable it every time the car starts.The RMP/throttle seems low when car is in reverse.   While releasing the break in reverse (without stepping on the gas) you can feel the car vibrate as it was going to cut out.  Obviously it doesn't cut out but surely it shouldn't vibrate.Honestly, I felt my switch over from the X3 to Q5 was a bad choice.   I end up paying more on a monthly basis thinking the 2018 Q5 was a step up.  In technology sense it was a step up, but my expectation of the basic car functions was missed.   Bottom line.  New isn't always better.  I think Audi rush the release for the major model change.
