New presidential limo is unveiled - and it can withstand rocket and chemical attacks. It's official call sign is Cadillac One, but it will always be known as the Obamobile. But his Secret Service agents have already been familiarising themselves with the machine they call 'The Beast', built by General Motors in Detroit and based on a Cadillac chassis.
Despite the protection afforded by Cadillac One, the Secret Service will be taking no chances when Mr Obama is sworn in as the 44th president. A three-mile security perimeter will be thrown around the U.S. Capital, with no vehicles allowed inside, to prevent a car bomb attack.
