Surprise, surprise, I like it.
I like the SAC idea, and the general coupe-ish shape.
Side profile looks great - coupeish & sleek, rear very dominant, the front is very aggressive.
The overall shape is very dynamic, especially the side profile - which is eg not the case in another SAC: Audi Cross Coupe with its forward-leaning rear.
Only the fascia (especially grille, hood & headlights) could be a bit less X5-ish.
