Vehicle with a movable front portion, in particular for pedestrian safety in the event of accidents

The vehicle (1) has a movable front portion (10) with a front bumper (16), a bonnet (18), and forward portions of two lateral fenders. The front portion is connected to a fixed structure with the interposition of a guide assembly (23) to slide in a longitudinal direction between a forward position and a withdrawn position under a control of an actuating assembly to obtain two different driving configurations. An independent claim is also included for a coupling assembly to connect a movable front portion to a fixed structure of a vehicle.
