Better looking than the Q5. That is not hard to do.

If the Macan is that much lower than the Q5 then the design is somewhat more compromised, in terms of utility, and as a consequence, the Audi's design is more dictated by interior volume constraints.  Hence, the significant difference in appearances.  The designers of the Q5, therefore, had more constraints than the Porsche team.
