The Beast is no different with its eight-inch thick body armour plating and five-inch thick bulletproof windows which insulate the President from all sorts of threats including chemical attacks.Its doors weigh similar to those on a Boeing-757 aircraft. The eight-tonner runs on shred and puncture resistant Kevlar-reinforced tyres with steel rims underneath which ensure that the vehicle does not come to a halt even if its tyres get damaged.
