Special-protection variant Mercedes-Benz M-Class Guard

The new special-protection variant of the M-Class is the latest addition to the extensive Mercedes-Benz Guard family. As with all Guard models, the armoured version of this popular SUV follows the brand-typical integrated special protection design principle. All the additional protection systems are taken fully into account right from the development phase of each model series and perfectly integrated into the vehicle's architecture. This enables all the advantages of the standard series-production vehicle to be retained, such as for instance the luxurious yet functional vehicle interior, the high level of active and passive safety, the exceptional ride comfort and the agile driving dynamics. Unlike its standard series-production counterpart, though, the Guard bodyshell has specific adaptations for the attachment of the armour elements, a front structure with reinforcing elements and modified doors. The armour itself includes: Windows of the highest optical quality Special laminated glazing with a uniform thickness all-round, polycarbonate layer on inside to protect against shards. In the un-transparent sectors perfectly tight-fitting formed special steel is used throughout. In the A-, B- and C- pillars and the firewall and roof, this steel also reinforces the passenger compartment and increases structural firmness. All the components installed comply with defined ballistic requirements, are subjected to constant ballistic control and are already correspondingly certified beforehand.

The new M-Guard meets the requirements of protection level VR4 according to testing guidelines BRV 2009 for special-protection vehicles with bullet resistance (according to Bullet Resistant Vehicles 2009). This ballistic classification designates ballistic resistance (VR = Vehicle Resistance) in terms of the weapons and calibre: in this case, among others, Magnum .357 and .44. Certification was carried out by the Ulm-based Ballistics Bureau. This independent, neutral, test ensures that the integrated protection concept is appropriate to face the hard requirements of real danger situations. The M‑Guard passed the following ballistic and explosives tests successfully:

Blasts, for example with DM51 hand grenade, according to test guidelines ERV 2010. Both in the front and in the vehicle rear, these were resisted by the M-Guard with the optional floor armour successfully

In spite of the increased weight caused by its armour, the M-Guard achieves the impressive ride comfort, great agility and extraordinary active safety of its series-production counterpart. The special-protection variant features as standard an AIRMATIC air suspension system with Adaptive Damper System (ADS) specifically adapted to the vehicle's special protection features. Stronger axle components compensate for the increased weight of the M-Guard superbly, Guard-specific torsion bars at the rear axle optimise roll behaviour in fast curves and when taking evasive action.

The M-Guard is exclusively available with tyres with run-flat capability and 5‑spoke 50.8 cm (20-inch) AMG light-alloy wheels. MOE tyres with run-flat capability make it possible to drive on safely for up to 30 km at a maximum speed of 80 km/h even if the tyre has suffered a total loss of air.

With the new ML 350 BlueTEC Guard there is a diesel power plant that is just as economical as it is agile for the first time in this segment. It offers the tried-and-tested V6-cylinder diesel engine with 190 kW output (258 hp) and a top torque level of 620 Nm. It meets the requirements of the currently strictest EURO 6 emissions standard. The V8 petrol-engine-powered ML 500 Guard with 300 kW (408 hp) and 600 Nm is available as an alternative.
