An athletic, sporting stance separates the new BMW M3 sedan from the rest of the range, bar its two-door coupé sibling. The design of the new four-door M3 powerhouse mimics that of the coupé with one noticeable difference: the sedan has a conventional steel roof rather than a carbon fiber top. The double-kidney grille has grown wider and the flat headlight design is more aggressive than on the 3-Series range, and the M3 boasts three large air intakes below the grille. The face of the 
new BMW M3 also includes a power dome in the middle of the aluminum hood which, though longer than that of the 3-Series sedan, blends into the two front side panel
s adorned with the signature M "gills," which incorporate the M3 logo. A discreet lip spoiler features on the trunklid to optimize the car's aerodynamics and reduces lift, while a split diffuser beneath the rear bumper takes up the shape of the air intakes at the front of the car.
Inside, the five seats are surrounded by powerful contours and flowing lines highlighting the concave and convex surfaces. The horizontal lines dominating the area around the dashboard as well as the harmonious surfaces of the side linings emphasize its dynamics. The cockpit control area tapers out between the front seats into a newly designed center console, which discreetly "swings" towards the driver. The choice of colors inside the M3 Sedan help the driver concentrate on driving and the footwells, parcel shelf, headliner, A-pillar trim and the upper part of the instrument panel are all finished in Anthracite.
