As opposed to the US version, which just looks casually indestructible.

the vehicle's chassis and driveline are assumed to be sourced from the GMC Topkick commercial truck.

Most details of the car are classified for security reasons; however, it is known[by whom?] that it is fitted with military grade armor at least five inches thick, and the wheels are fitted with run flat tires that makes the vehicle drivable for a certain period of time. 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.[citation needed] The vehicle's fuel tank is leak-proof and is invulnerable to explosions.[citation needed] Due to the thickness of the glass, much natural light is excluded, so a fluorescent halo lighting system in the headliner is essential. The outside crowd is only heard through internal speakers. The car is perfectly sealed against biochemical attacks and has its own oxygen supply and firefighting system built into the trunk.[8] Unseen at a glance are two holes hidden inside the lower part of the vehicle's front bumper, which are able to emit tear gas.[citation needed] The vehicle can also fire a salvo of multi-spectrum infrared smoke grenades as a countermeasure to a Rocket-propelled grenade (RPG) or Anti-tank missile (ATGM) attack and to act as a visual obscurant to operator guided missiles.[citation needed] This is fired remotely by the USSS countermeasures Suburban which trails the limo and contains the sensors to detect the launch of such an attack.[citation needed] The limo is equipped with 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.[citation needed] Kept in the trunk is a blood bank of the President's blood type.[9][10] 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.

Dear lord.
