Cadillac One


Entering into service on January 20, 2009, Cadillac One is a common name for the Presidential State Car of United States President Barack Obama. Unlike previous presidential limousines, it is not at all based on a production vehicle. Although badged as a Cadillac, the armored limousine uses the four-wheel drive chassis and powertrain of a General Motors medium-duty truck (the Kodiak/TopKick). As it is not a production vehicle, the car borrows parts from several different vehicles in the Cadillac lineup (primarily the Escalade and STS). For security reasons, many other details about Cadillac One remain classified.
