The architecture of the every model of the BMW 1 series is characterized by a distinctive shoulder line. This feature is particularly striking in the new BMW 1 series convertible, where it imparts the elegance that is typical of all BMW convertibles. The hood, shoulder and flat rear create a single seamless area which conjures up associations with the deck of a motorboat. Horizontal lines as well as generous and taut surfaces dominate the interior design. This is combined with the striking exterior design to create a stylish and elegant overall appearance within compact dimensions.
