BMW Z4: Retractable Hardtop

Either and or.

The retractable hardtop of the BMW Z4 Roadster.

The first BMW roadster with a hardtop. Its sophisticated design means the characteristic low-slung appearance remains unaltered even with the top down. This is possible thanks to the optimal folding of the two aluminium roof shells in 22 seconds. With the top closed, the roof line of the roadster adopts a coupé-style silhouette, and the generous side and rear windows ensure captivating panorama views. Whichever option you choose, you can open and close the roof safely up to a speed of 40 km/h. Whether you choose to drive with the roof open or closed, it's never a question of style but always of the moment.
