Abstract: A body structure of a passenger car, and especially of a convertible, features at least one side door on each longitudinal side of the vehicle. The side door, when closed, connects to adjoining fixed pillars via hinges at one end and via a lock assembly at the other end. For improved crash resistance of the body structure of a passenger car, and especially of a convertible, with a rear engine in the event of a head-on collision, a buttress assembly is installed between the rearward rim of the side door and the adjoining lock-side pillar. The buttress assembly effectively holds the side door in its closed position in the event of a head-on collision, while at approximately the level of the buttress assembly, the side door is braced by a hollow strut that extends in the longitudinal direction of the vehicle.

Abstract: A motor vehicle, particularly a passenger car, having an extendable air guiding device and at least one elongated additional brake light in the rear area. An additional brake light arrangement is provided at reasonable cost, which can be used for a coupe version as well as for a convertible version of a motor vehicle provided with an extendable air guiding device. On a vehicle body part disposed in front of the air guiding device, a first additional brake light is arranged and, on a transversely extending, rearward edge area of the extendable air guiding device, a second additional brake light is arranged. According to the position of the rearward-side air guiding device, at least one of the brake lights is connected which is visible from the rear at the time.
