Gregg Merksamer at the New York Times reports President Obama will be riding in a new limousine, seen here unfinished and on a road test:


Speculating on some of the armament, Merksamer says:

[…] television clips showing George W. Bush entering and exiting the rear doors of his limos indicate that the windows are at least 5 inches thick, nearly twice the depth of what was used on presidential limousines in the 1980s and ’90s.

While I do not know what type of weapons such thick windows are designed to guard against, a half-inch of transparent armor is enough to stop a .44 Magnum round at point-blank range; at a thickness of 1.25 to 1.5 inches, the same material can withstand higher-velocity bullets fired from military assault rifles.

Were an attack to occur, the ballistic forces of bullets fired into the windows would be absorbed within a succession of glass and plastic layers, after which a flexible inner coating known as an antispall shield would keep glass from entering the passenger compartment.

The Times also has a gallery of past presidential rides. Interesting to see the progression from car to tank.
