To many, the 5 Series is considered the world’s most successful business sedan. So you know the top-end M550i version won’t cut any corners in terms of styling. Rolling on 20-inch light alloy wheels, the new M550i M aerodynamic package adds an M rear spoiler with Gurney flap on the boot lid, accentuating the sporty, dynamic lines of the new BMW 5 Series, at the same time as optimizing the airflow around and over the car, while a group of features are finished in a metallic Cerium Grey, including the M Performance bars on the front air intake and the two Air Breathers at the sides plus the exterior mirror caps and the kidney grille surround.
