The roof folds or rises in about 22 seconds, not only for added safety, but also for better visibility and a greater sense of space and light for passengers. Since the roof is equipped with an enlarged front window and side windows, the view has improved by 38% compared to the previous 3-series convertible.

The unique way of folding the roof also allows you to maximize the available space for the trunk. With a raised roof with a capacity of 350 liters beckons, and with a lowered roof, the trunk can hold up to 210 liters of luggage. For the first time in the world, the backs of the rear seats of a 3-series convertible can also be folded to get additional storage space. An end-to-end loading system with a transport bag can also be specified as an option, allowing longer or bulkier items to be placed, and it can be used even when lowering a folding metal roof. For greater practicality, the folding roof can be electronically lifted out of the luggage compartment so that longer items, such as golf clubs, can be secured before they are re-folded.
