Presidential state car (United States)

The United States presidential state car (nicknamed "The Beast",^[1][2][3] "Cadillac One",^[4][5] "First Car";^[6] code named "Stagecoach"^[7][8]) is the official state car of the president of the United States. Since its introduction in 2018, the currently employed custom Cadillac known as "The Beast" is widely regarded as the most heavily fortified automobile in the world.

United States presidents embraced automotive technology in the early 20th century with President William Howard Taft's purchase of four cars and the conversion of the White House stables into a garage. Presidents rode in stock, unmodified cars until President Franklin D. Roosevelt's administration bought the Sunshine Special, the first presidential state car to be built to United States Secret Service standards. Until the assassination of John F. Kennedy, presidential state cars frequently allowed the president to ride uncovered and exposed to the public. President Kennedy's assassination began a progression of increasingly armored and sealed cars; the 2009–2018 state car had five-inch (130 mm) bulletproof glass and was hermetically sealed with its own environmental system. The current model of presidential state car is a unique Cadillac that debuted in September 2018.

Decommissioned presidential state cars are dismantled and destroyed with the assistance of the Secret Service to prevent their secrets from being known to outside parties. Late 20th-century and 21st-century presidential motorcades have consisted of 24–45 vehicles other than the presidential state car, including vehicles for security, healthcare, the press, and route-clearing, among others.
