President-elect Barack Obama's new ride has arrived -- and it's a beast.

As first reported by FOXNews.com last November -- and Tuesday by The Detroit News -- a new model of a presidential limousine made by General Motors Corp. has been delivered to the Secret Service and will make its debut on Inauguration Day.

The vehicle, referred to by the Secret Service as "the beast," will reportedly feature heavy armor that is at least 5 inches thick and comes complete with run-flat tires, bulletproof glass and a completely sealed interior to ward off a chemical attack, among many other high-tech security features.

One news agency, noting its 8-inch-thick doors, said the limo can withstand a "direct hit from an asteroid." But GM spokeswoman Joanne K. Krell laughed off the comments.

The new limousine also includes larger windows and better visibility for the president, a spokesman for the automaker told the paper.

Cadillac has previously disclosed that the limo's interior is made of hand-stitched leather and includes a 10-disc CD player.

"The president is not riding in a medium-duty truck, nor he is riding in a sedan," a GM representative told the Detroit News, it is a "unique" vehicle.

The armored 2009 Cadillac Presidential Limousine will make its debut at Obama's Jan. 20 inauguration in Washington.

The Secret Service and GM say they'll reveal more about the custom vehicle's specifications next week after training with the new limousine at a facility near Washington.

Older-model presidential limos will remain in use for the vice president and traveling world leaders. The previous model, a modified Cadillac DTS, was introduced at President George W. Bush's second inauguration in 2005.
