Obama's Limo is massively over-engineered, and is in theory able to operate as a Mobile life-support system and armoured cell capable of withstanding all but the most well-equipped and determined attack. (via)
the vehicle is fitted with military grade armor at least five inches thick, and the wheels are fitted with run flat tires … The doors weigh as much as a Boeing 757 airplane cabin door. The engine is equipped with a Eaton Twin Vortices Series 1900 supercharger system. The vehicle’s fuel tank is leak-proof and is invulnerable to explosions. The car is perfectly sealed against biochemical attacks and has its own oxygen supply and firefighting system built into the trunk. … two holes hidden inside the lower part of the vehicle’s front bumper … are able to emit tear gas The vehicle can also fire a salvo of multi-spectrum infrared smoke grenades as a countermeasure to an Rocket-propelled grenade (RPG) or Anti-tank missile (ATGM) attack and to act as a visual obscurant to operator guided missiles. … The limo is equipped wit
h a driver’s enhanced video system which allows the driver to operate in an infrared smoke environment. This driver’s enhanced video system also contains bumper mounted night vision cameras for operation in pitch black conditions. Kept in the trunk is a blood bank of the President’s blood type. Interestingly, there is no key hole in the doors. A special trick, known only to Secret Service agents, is required to gain access to the passenger area. Furthermore, the entire limo can be locked like a bank vault.
They've thought of everything? No? Millions of dollars worth of high security hardware were defeated by nothing more complicated than a speed-hump or pothole. (via)
The president's fucked when he comes to the UK then, if he hopes to drive around central London in "the Beast". If the designers of the vehicle had any sense (of course they don't, they're American & American cars are all badly-designed crap, even it seems, the President's), they'd have taken a leaf out of the Soviet book. In order to avoid such "beachings", inevitable in a long-wheelbase vehicle, some variants of the BRDM series of Scout cars in service with light motor rifle units had a pair of 'belly wheels' to aid, in this instance in trench crossing, but they'd help negotiate a speed-bump too.

Such a simple system would help the limo get round narrow, potholed or steep European roads without beaching, and without leaving its occupant looking like a dick.
