It looks as if that render was given a fifteen minute deadline hence its current X6 with 4er conceptitis detailing. Very lazy.
The new X4 determines the new approach to the sportier coupe activity vehicles, which means they will differ much more in appearance than the standard SAV.
It is not a 4er in face but it gets that added expression of dynasm like the coupe in its more sleeker and widened track and muscular haunches.
The new X6 will also differ in styling to the standard X5. Employing a more dynamic look rather than simply being a twin.
Another render of the X4. But still not as accurate yet.
The idea is familiar but the execution is very distant.
