• GUARD: Special protection version of the new S-Class.

“For what really counts.”

Heads of state and business leaders can take this S-Class slogan literally when they entrust their lives to the new special protection version of the luxury model. Because the new S 680 GUARD 4MATIC meets the highest ballistic test level for civilian vehicles with protection class VPAM VR10, while also offering exceptional resistance against explosive charges. The certification by Beschussamt Ulm (ballistic testing authority) was carried out for the first time using so-called biofidelic dummies. With bone and soft tissue-like constructions, these test dummies imitate the human body particularly realistically. The S 680 GUARD 4MATIC is the first GUARD saloon from Mercedes-Benz with all-wheel drive and is powered by the familiar V12 (M279) with 450 kW/612 PS. The S 680 GUARD 4MATIC will celebrate its world premiere at the IAA in Munich (7–10 September 2021).

Focus on people and their safety.

The S 680 GUARD 4MATIC is one of the most customer-oriented products from Mercedes-Benz. The new S-GUARD focuses on its passengers and their protection. No other series-produced saloon fulfils the highest protection class for civilian vehicles quite as comprehensively. And at the same time, quality and durability are at series standard, thanks to extensive development and testing activities. The new S 680 GUARD is built to “protect what matters”.

Integrated protection system (iSS) reaches new level.

Mercedes-Benz has been building special protection vehicles since 1928 and thus for over 90 years. Customers of the new S 680 GUARD 4MATIC benefit from these many years of experience. The integrated protection system (iSS) reaches a new level: whereas the necessary protective materials were previously integrated into the standard bodyshell structure for the GUARD saloons, a GUARD-specific bodyshell of protective elements has now been developed. This self-supporting protective cell represents the core of the iSS. Ultimately, the (aluminium) outer skin serves as a design shell and ensures an inconspicuous appearance. In addition to the armouring, the iSS includes the adaptation of the suspension, engine and transmission to ensure handling that is virtually on a par with that of the series vehicle. Due to a parallel development process alongside the large-scale production models, the longevity of the GUARD vehicles also reaches series production level.

In addition to the unseen armouring elements, the transparent area of the windows is an integral and essential part of the protection concept. The material and thickness of the multi-layer glass “sandwich” meet the high requirements of the VR10 safety classification. The inner surfaces of the glass are coated with polycarbonate for splinter protection. Despite their comprehensive protective effect, they offer excellent visibility. And they have been integrated in such a way that they are not noticeable at first glance – another significant advantage of the integrated protection system.

Interior: design philosophy of Sensual Purity.

The interior space also benefits from the elaborate iSS concept, as the comfort dimensions largely correspond to those of the long S-Class. As with the production model, it was possible to keep the joins in the bodyshell to a minimum, so fulfilling the “Seamless” claim of the Sensual Purity design philosophy. And when it comes to comfort and appointments, the four- and five-seater versions can both hold their own with their sister models: more than 80 individualisation options are available for the S-Class, from Active Ambient Lighting and a media display featuring OLED technology through to a First-Class rear suite and rear airbag. There are almost no restrictions on trim parts and colour combinations. However, optional extras that contradict the protective purpose, such as a sliding sunroof, are not available.

Highest civilian protection class.

The testing was carried out by the Beschussamt Ulm, the only testing and certification body for weapons, ammunition and safety technology in the German state of Baden-Württemberg and one of the most state-of-the-art institutes of its kind. The new S-Class GUARD meets the requirements of the highest civilian protection class VR10 according to the standard VPAM BRV version three (Bullet Resistant Vehicles). In this test, the body and windows must withstand fire from an assault rifle using armour-piercing ammunition. The S 680 GUARD 4MATIC also meets the requirements of Germany’s Federal Criminal Police Office (BKA).

New door actuators and hydraulically operated window lifters.

The highest level of protection combined with the best possible comfort for passengers and staff, that is the GUARD philosophy. This can be illustrated with two examples. The S 680 GUARD 4MATIC, for example, features newly developed door actuators. Although the doors are very heavy due to their armouring, this electro-mechanical system means that only low operating forces are required when opening and closing. This applies not only on level ground, but also when the vehicle is on a slope. The stepless door arrest also proves its worth in this situation. The door’s sensor technology detects when and how it is to be moved or stopped. Algorithms from human-supporting robotics (cobots) are used. The system facilitates the work of the bodyguards in particular, and at the same time they can keep one hand free.

There is also a lot of intelligence in the hydraulically (instead of electrically) operated window lifters. Even if the on-board power supply fails, emergency operation is possible, i.e. closing in the event of an attempted attack. In each door there is a corresponding unit consisting of a compressor and valve block together with a pressure accumulator.

Powertrain: first GUARD saloon with 4MATIC.

The V12 biturbo power unit has been extensively revised for its use in the new S-Class generation. The exhaust gas turbochargers, exhaust manifold and air ducting were all adapted. Also new is a closed-loop petrol-engine particulate filter. The V12 has an output of 450 kW/612 PS and a displacement of 5,980 cc. The maximum torque is 830 Nm from 2,000 rpm. The most important features of the engine include an all-aluminium crankcase, a one-piece chain drive, a forged crankshaft made of high-quality quenched and tempered steel, forged pistons and a multi-spark ignition system with twelve double ignition coils.

90-year experience in special-protection vehicles.

It started way back with the 1928 Nürburg 460 model, when Daimler-Benz became the first company to begin factory-fitting saloons with special protective features to shield the occupants from gunshots and explosives. Mercedes-Benz also developed specially protected variants of subsequent luxury-class and prestige vehicles, such as the “Grand Mercedes” 770 and the 500 model. The Japanese Emperor Hirohito personally chose an armoured “Grand Mercedes” as a befitting vehicle for his own use. This vehicle was delivered in 1935.
