The V12 bi-turbo 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 particulate filter. The V12 has an output of 450 kW/612 hp and a displacement of 5980 cc. The maximum torque is 830 Nm from 2000 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 twin-power ignition coils.

Features of the all-wheel-drive system, combined here for the first time with the twelve-cylinder engine, include a low system weight, optimal traction and driving safety, and the highest levels of ride comfort and driving dynamics. The standard torque distribution for this model is 31 percent to the front axle and 69 percent to the rear axle. Among other things, the all-wheel drive was adapted to the higher vehicle weight of the GUARD version with stronger side shafts.

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 body shell structure for the GUARD saloons, a GUARD-specific body shell 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 cover 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 production 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.

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 panel gaps in the body shell 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 customisation options are available for the S-Class, from active ambient lighting and a media display featuring OLED technology to a First-Class rear suite and rear airbag. There are almost no restrictions on trim and colour combinations. However, optional extras that contradict the protective purpose, such as a sliding sunroof, are not available.
