Ahead of its official unveiling at the Frankfurt Motor Show, the Citroen Cactus concept is previewed with this spate of leaked images showing off a futuristic crossover with a number of unique elements. They're highlighted by a system of Air Bumps -- air-filled blisters on the sides of the vehicle and around the headlights -- replacing the functionality of a traditional bumper, as well as touch pads in lieu of conventional door handles. The minimalism continues throughout the interior, where a front bench seat is complemented with a dashboard that centers most of the controls on a large touchscreen display. Check out detailed looks below.
