Short of riding around in a tank, among the highest levels of protection while motoring are provided by armored Mercedes-Benz. The German automaker has been protecting heads of state and captains of industry for 80 years now, and to mark the anniversary has officially released the new S600 Pullman Guard limousine, which was initially announced way back in February 2007.

Based on a stretched version of the standard, off-the-shelf S600, the Pullman is engineered right off the assembly line to withstand handgun fire, grenades and explosive charges to the stringent B6 and B7 ballistic protection standards. The extra weight of all that armor is pulled around by Mercedes' top-of-the-line 517-hp 5.5-liter twin-turbo V12 and is further supported by run-flat tires, a self-sealing fuel tank and integrated fire suppression system. Of course, the stretched limousine can be specified with all manner of luxury equipment, coddling its occupants in security and opulence. All that protection and luxury surely doesn't come cheap, but for wealthy public figures under threat, price is presumably no object. However, Mercedes also offers an armored E Guard and G Guard as well as the standard-wheelbase S600 Guard.
