Maximum comfort and uncompromising functionality are the key features of the new BMW Z4 convertible top, with its incredible electro-hydraulic mechanism. The two-section steel roof of the BMW roadster opens automatically with a smooth movement, as each element rests on the other, forming a compact package. The rear cover of the convertible opens backwards, and after the roof is fully open or closed and the hard part is locked, the driver can open the trunk lid in the usual way. The top opens in just 22 seconds and closes in 23 seconds. The back cover is also equipped with a smooth closing function, which smoothly and automatically lowers the entire system down.

To ensure optimal use of the car's capacity in any situation, the roof and luggage compartments are separated from each other by an adjustable partition that conveniently rotates when the system is open to ensure maximum luggage capacity. Another convenient feature is that the top can be opened using a remote control if there is a comfortable access system. Like the control switch inside the cabin, for safety, the remote control button must be kept pressed during the entire opening process, since the movement of the elements will be interrupted when the button is released.
