Very wide but only as wide as necessary.

The two-stage tailgate on the BMW ActiveHybrid X6.

To make sure the tailgate of the BMW ActiveHybrid X6 never strikes a garage roof or other obstacle, the angle of opening can be set to one of two settings. When the tailgate is in the lower position, the two-stage gas damper lets you open it fully using the pull-and-release principle familiar from ball-point pens. With the "automatic tailgate operation" option, you can even set five stages in the iDrive menu – and then open or close the tailgate from the comfort of the cockpit, just by pressing a button. This version also includes a safety feature in the motor to prevent jamming.
