The BMW mid-size 4-series sports convertible embodies the very essence of dynamics and aesthetic appeal in the premium segment. The "4" in the name of this new product line for the convertible and emphasizes not only its outstanding design, but also represents something more than its cousins BMW 3 series, putting the 4 series on a par with the larger convertibles 6 and 8 series.
New elements of the BMW 4 Series convertible are air intakes located behind the front wheel arches to reduce drag. The muscular wheel arches and wide track of the convertible give it an aggressive look with its protruding horizontal lines.
The design language of the first BMW 4 series convertible is reflected in the recognizable and elegant silhouette of the car with balanced proportions when the roof is lowered, and in the coupe–like profile of the roof line – without a central pillar - when the rigid roof is raised. The three—section folding rigid roof is distinguished by improved sound insulation with a "noise-absorbing" ceiling, which ensures silence and comfort of passengers in all weather conditions - even in winter.
The iDrive controller, conveniently located on the center console, and the armrest between the front seats provide convenience and comfort in the cabin.
