The new presidential limousine is officially called Cadillac One, but everyone already knows it as the Obamamobile. It was built by General Motors.
The company refuses to give precise details of how it will perform its primary purpose - protecting the president.
But bulletproof glass and armourplatingare standard throughout and the car is hermetically-sealed to withstand chemical weapons.
As with previous presidential limos it is packed with electronic communication systems to allow Mr Obama to keep in contact with the outside world.
Cadillac One will debut at the inaugural parade on Tuesday. Link -via the Presurfer
