Current model

The current Presidential Limousine is a 2006 hand-crafted, armored version of the stretch Cadillac DTS (DeVille Touring Sedan), first used on January 20, 2005 during the second inauguration parade of George W. Bush. The vehicle was custom built by a team formerly called O'Gara, Hess and Eisenhart, founded in Fairfield, Ohio in 1942, specializing in armoring limousines for presidents and heads of state, and now a subsidiary of BAE Systems.The Secret Service refers to the heavily-armored vehicle as "the beast".

The limousine is airlifted for domestic and international use primarily by U.S. Air Force C-17 Globemaster III. When the President travels on domestic and working international trips, Cadillac One displays the American and Presidential flags. When the President performs a state visit to a foreign country, the Presidential flag is replaced by the foreign country's flag. via
