Fully Armoured Luxury SUV - Conquest Knight XV unveiled at the 2008 SEMA Show in Las Vegas.

Highest-Protection vehicles, engineered to resistance level B6/B7, provide effective protection against the threat posed by terrorist attacks. Their armour is designed to resist rifle-launched projectiles from military weapons which have a velocity almost twice that of bullets fired from a revolver. They also offer resistance to shrapnel from hand grenades and explosive charges.

The first special-protection models from Mercedes-Benz differed from those of later years not only with regard to their design and performance, but also in terms of their technical basis. Instead of having a self-supporting body structure, which is now the norm, their bodies were mounted on strong frames. The weight of the protective steel plates therefore called for less extensive design changes than is currently the case.
