The new Mercedes-Benz S 680 GUARD 4MATIC - Further technical refinements - new door actuators and hydraulically operated window regulators

The highest level of protection combined with the best possible comfort for passengers and personnel - that is the GUARD philosophy. This can be illustrated with two examples. The S 680 GUARD 4MATIC, for example, has newly developed door tractors. Although the doors are very heavy because of their armor, this electro-mechanical system allows low operating forces during opening and closing. This applies not only on level ground, but also when the vehicle is parked on a slope. This is also where the stepless door locking system proves its worth. The door's sensor system detects when and how it is to be moved or locked. Algorithms from human-assisted robotics (cobots) are used for this. The system makes work easier for the bodyguards in particular, while at the same time keeping one hand free. The hydraulically (instead of electrically) operated window regulators also contain a great deal of intelligence. Even in the event of a power failure, they can be operated in an emergency, i.e. in the event of an assassination attempt. Each door is fitted with a compressor, valve block and pressure accumulator. Other special equipment designed specifically for the S 680 GUARD 4MATIC includes a fire extinguishing system with automatic triggering function and an emergency fresh air system that protects occupants from penetrating smoke or irritant gases and supplies them with fresh air. Other special GUARD options include extensive authority equipment such as siren, flashing lights and radios, as well as an endangered person alarm system.
